The best picture application tools

Save bandwidth and accelerate your site’s opening with these absolute giveaway tools

When you’re looking to boost your website’s performance, some would suggest we burst true into a minute research of any page: a HTTP requests you’re making, any redirects involved, a position of scripts and character sheets, and more.

But while there’s no doubt that examining these issues can help, it’s critical to cruise a basis first. In particular, are we certain that any graphics you’re regulating are wholly optimised for a web?

You’ve substantially already done certain to name a suitable format for any picture as good as gripping a distance (in pixels) to a minimum. Maybe you’ve reduced a JPEG peculiarity environment as many as we can. (Although if you’re not utterly assured in your believe of a fundamentals afterwards a Designer’s Guide to Image Compression might help.)

The hapless existence is that, no matter how delicately we pattern your images, a graphics apparatus you’re regulating will not save a finished files in a many fit way. And so flitting those images by a application apparatus can revoke their distance considerably.

Exactly how many we can save is wily to contend for certain as it depends unequivocally many on your source graphics. Some JPGs might usually dump by 50-100 bytes. It’s not startling for unchanging web graphics to be dense by 10-40%, though, with no detriment of picture peculiarity (and lossy application techniques, maybe shortening colours or reencoding JPEGs can cut record sizes even more).


Which programs are a best, then? Good question. To assistance yield an answer we’ve pitched 18 of a tip contenders opposite any other.

The bulk of these are Windows-based lossless application collection as they’re a many engaging (reducing record distance yet shortening picture peculiarity is a unequivocally appealing idea). But we’ve also enclosed lossy application options, Mac programs and web services, so there unequivocally is something here for everyone.

We afterwards asked any package to restrict a same sets of GIF, PNG and JPG images, any of that were tangible web graphics we’d found on a operation of genuine sites, and done a note of a savings.

We checked a programs for other issues, too. Were they easy to use? How discerning was a application process? And how reliable? Could a module infrequently boost an picture size, for instance?

And a formula were unequivocally engaging and mostly a genuine surprise. Keep reading to find out what we discovered.

The programs

1. AdvanceCOMP 1.15

Platform: Windows

An ancient authority line apparatus with a smallest of help, AdvanceCOMP isn’t accurately going to seductiveness to a normal PC user.

If you’re not put off by collection files, though, it’s easy to use.

A elementary line like ‘for %a in (“C:PNG FileFolder*.png”) do advpng -z -4 “%a”‘, for instance, will means a module to request a lossless application algorithm to any record in your folder, replacing a strange with a (hopefully) smaller version.

However, a finish formula are unsatisfactory with a exam PNG web graphics dropping by an normal of 14.2% (only one apparatus here did worse).

That is of march intensely improved than doing zero during all, though. And if we wish to mix several collection together to get a extent PNG application afterwards AdvanceCOMP might be means to play a part.

2. Caesium 1.4.1

Platform: Windows

Caesium is a elementary open source apparatus that helps we to restrict PNG, JPG and BMP formats.

It’s an easy module to use. Click a Add program, name your images, name an Output folder, click Compress and you’ll have your formula within seconds.

BMP application isn’t of seductiveness to us, and a program’s JPG record isn’t anything special, either. There’s no lossless option; it usually reencodes a record during your selected peculiarity setting.

Caesium does yield support lossless PNG compression, nonetheless this has a vital limitation. It can usually outlay 24-bit files, so if you’re regulating anything else afterwards your images will substantially grow in size.

And a program’s formula clearly illustrated a problem, with many of a exam PNG web graphics indeed augmenting in size. Fortunately, we can tell Caesium not to write a record in that case. But even afterwards a altogether distance of a images fell by a unequivocally handicapped 1.2%. Clearly many people will be improved off elsewhere.

3. FILEminimizer Pictures 3.0

Platform: Windows

FILEminimizer Pictures takes a some-more impassioned proceed to picture application than many of a competition. By default it might change formats, resize images, re-encode JPEGs with a reduced peculiarity and frame out metadata in an bid to cringe your pictures. Although, fortunately, we can adjust many of this in a program’s settings.

In use, a module follows a common format. Once you’ve forked it to your source files, selected an outlay folder, maybe configured an choice or two, one click is adequate to start optimisation. And it’s sincerely quick, so you’re not kept in torment for unequivocally long.

How good does it do? That sundry depending on format – during slightest for a tests. PNG application rates were zero special during 26.8% (some lossless collection do better); GIF application was a some-more normal 16.5%; yet a JPG web graphics forsaken in distance by 39.3%, a largest tumble in this group.

Whether this arrange of rebate is adequate to transparent compromising picture peculiarity is another matter. FILEminimizer Pictures module is versatile, configurable and easy to use, though, and if that’s some-more your priority afterwards it might be value perplexing a module for yourself.

4. FileOptimizer 2.10.135

Platform: Windows

There’s no jealous FileOptimizer’s ambition. Not usually can it restrict JPG, GIF and PNG images, yet it can also work with executable files, archives, Microsoft Office documents, PDF files, and a list goes on.

Surprisingly, though, there’s no boost in complexity. In fact, a module has one of a many candid interfaces here: drag and dump your images onto FileOptimizer, right-click, name Optimize and that’s it.

This morality has a down side as your source files are transposed by a program. The originals are sent to a Recycle Bin so sojourn recoverable, for a while during least. But this could be a problem.

Of march it’s application that unequivocally matters and here is where FileOptimizer delivers some good results.

For instance, a module shrank a PNG exam graphics by 42.2% – a best lossless application opening in this group. JPEG and GIF application rates were some-more customary during 17.7% and 15.9% respectively, yet there’s still a lot to like about FileOptimizer generally if we can also use it to restrict other downloads on your site.

5. ImageOptim 1.4.0

Platform: Mac

ImageOptim is a Mac apparatus that optimises GIF, JPEG and PNG images by behaving as a front finish for a horde of other applications: PNGOUT, AdvPNG, Pngcrush, extended OptiPNG, JpegOptim, jpegrescan, jpegtran, and Gifsicle.

The module is all about lossless application – stealing comments, colour profiles and so on – rather than re-encoding or shortening a series of colours. As a outcome it won’t cut record sizes by utterly as many as some of a competition, yet during slightest we don’t have to worry about any detriment in picture quality.

ImageOptim’s front finish works well, too. Drag on a singular file, a group, a folder or whatever, and it immediately starts compressing any picture and displaying a results. The module isn’t a fastest apparatus around, yet unless you’re giving it thousands of HD JPEGs that’s substantially not going to be a problem.

The finish formula were solid, yet not spectacular. Our GIF web graphics were reduced in distance by 16.2%, PNG’s by 17.8%, JPGs by 18.3%.

You can do improved elsewhere with sold tools, then. But if we usually wish a single, elementary Mac-based tool, that can hoop GIFs, JPEGs and PNG files, afterwards ImageOptim looks like a unequivocally essential choice.

6. JPEGmini Lite 1.4.1

Platform: Mac

JPEGmini is an engaging Mac app with a two-pronged proceed to timorous JPEGs.

First, it uses a intelligent algorithm to figure out how many an picture can be dense yet manifest effects (so a module isn’t lossless, yet it’s not usually re-encoding during some bound peculiarity setting, too).

And afterwards a module uses a possess JPEG encoder to try and broach a many restrict files possible.

There’s copiousness going on in a background, yet zero of this is manifest to a user. Just drag and dump your cinema onto a module (a extent of 20 per day in a giveaway version) and it’ll reinstate a originals with dense versions.

The formula here can change greatly. Our JPG web graphics saw tiny reduction, 8.2%, yet when we presented a module with 25 vast digital photos they forsaken by 71.3% and with tiny apparent peculiarity loss.

For elementary web graphics JPEGmini doesn’t do anything too amazing. The application possibilities ramp adult intensely as your images get larger. If your graphics are on a massive side afterwards it’s unequivocally value giving a module a hearing to see how it works for you.

7. jStrip 3.3

Platform: Windows

jStrip is a lossless application apparatus for JPEG files, that removes non-essential information: thumbnails, comments, colour profiles, additional bytes during a commencement or finish of a file, and assorted other pieces and pieces.

The information mislaid per record will generally be tiny as there’s no re-encoding. This was quite conspicuous when we presented JStrip with some high fortitude JPG photos. Those files were so vast that a module could usually revoke a distance by around 1%.

If a files you’re looking to restrict are already small, though, a rubbish is expected to be distant some-more significant. And certain enough, when we upheld a representation JPEG web graphics by jStrip, they fell in distance by an normal of 16.1%.

The module isn’t perfect. By default it will reinstate a images we mention with dense versions, for instance, so you’ll need to remember to work with copies. But differently jStrip is a discerning and easy proceed to marginally revoke a distance of your JPEG images.

8. OptiPNG 0.7.3

Platform: Windows

OptiPNG is a renouned authority line-based lossless PNG application tool, frequently reused within other packages (such as PNGGauntlet, see later) to hoop optimisation tasks for them.

The module is a tiny improved documented than many identical packages, so don’t indispensably be put off by a authority line nature. The download comes with a PDF record explaining a several switches and options, for instance, that is useful (although you’ll still need copiousness of picture optimisation knowledge to wholly know this).

And a results, even with a default application settings, seem to be unequivocally excusable with a exam PNG web graphics dropping in distance by a corpulent 32.2% on average.

If you’re looking for an easy life, afterwards PNGGauntlet provides a simpler, GUI-based proceed to try a module (and improved altogether compression). But if you’re looking to mix a series of authority line collection to broach a best probable formula afterwards OptiPNG might be value including.

9. PNGGauntlet

Platform: Windows

PNGGauntlet is an engaging tool, radically a frontend for 3 other open source programs (PNGOUT, OptiPNG, DeflOpt) that do a genuine application work.

In operation it works many like a competition. Drag and dump in your source images, name an outlay folder, click a “Optimize!” symbol and wait.

And wait, and wait, and wait, maybe. Presumably since it combines a work of 3 tools, PNGGauntlet can be intensely slow, holding 50:44 to restrict 25 hi-res photos in a PNG format.

The formula are impressive, though. In a PNG Web Graphic test, a module shrank a 50 images by an normal of 41.3% and even a photos forsaken by 7.75%.

Is this unequivocally adequate to transparent a opening issues? We’re not sure, yet if we need a peculiarity PNG application apparatus afterwards PNGGauntlet unequivocally should be on your shortlist.

10. PNGOptimizer 2.2

Platform: Windows

At a tiny 146KB download, PNGOptimizer is a smallest module here, so it’s no genuine warn that a interface is a tiny basic. Or that it concentrates on PNG files.

You do get a startling series of application options, though. PNGOptimizer can mislay interlacing, for instance; keep, remote or reinstate a credentials colour; and mislay content or a image’s earthy measure in pixels.

And a module can even import GIF, BMP or TGA files, saving them to PNG according to your selected options.

You still don’t get a some-more modernized options accessible with some of a foe and that was manifest in a exam results. PNGOptimizer usually nude an normal 3.6% off a hi-res PNG photos.

The module did many improved on web graphics, though, achieving an normal 39.8% application rate. If we usually wish a tiny and elementary PNG-crunching apparatus afterwards PNGOptimizer might be good enough.

11. PNGOUTWin 1.5.0

Platform: Windows

PNGOUT is one of a best picture application collection around. Unfortunately, it’s also rather ungainly to use, being command-line formed and with no collection estimate support. But if that’s a problem afterwards we could always opt for a blurb frontend, PNGOUTWin.

The module is rarely configurable. You can use PNGOUTWin to overwrite your strange images, or save a outlay to a new folder. And there are options to safety record times, adjust a application level, optionally keep some (or all) PNG chunks, and more.

It’s also easy to use. Drag and dump your images onto a module window and it immediately starts a application process, regulating mixed threads to work on several images during a same time.

And a formula are also excellent; a PNG web graphics were reduced in distance by 40.5% (not bad during all for lossless compression).

Unfortunately for a author, there are now giveaway PNGOUT frontends, such as PNGGauntlet, that also make it unequivocally easy to use a module (and indeed grasp even improved application levels by mixing it with other tools). And so, while PNGOUTWin is an considerable tool, it’s substantially not value a $14.95 (personal licence)/ $29.95 (corporate) seeking price.

12. PUNYpng

Platform: web

Far some-more versatile than a name suggests, PUNYpng is a web use that can indeed request lossless application to GIF and JPG images, as good as PNGs and we can open an comment for free, too. It’s a tiny restrictive; we can usually upload 15 images in a batch, any no some-more than 150KB in size.

Although, if that’s not an issue, it’s elementary to use. Click an Upload Images symbol on a site, afterwards wait as a cinema are uploaded and compressed. A news explains what’s happened and we can download a full set as a ZIP file.

The giveaway comment relates lossless application only. PUNYpng delivers means formula here and typically reduced a several exam record sets by between 16 and 32%.

But compensate from $2 a month and we can ascent to a PRO account, that adds a lossy application choice and allows we to upload some-more and incomparable files.

Is it value it? We still cite a preference of customer software. If we need a web service, though, and won’t be influenced by a restrictions, PUNYpng is both effective and easy to use.

13. RIOT 0.4.6

Platform: Windows

While RIOT is free, it’s one of a usually programs here that will try to implement additional module during a setup process. Be certain to transparent a applicable checkbox during designation if you’re not interested.

But with that con out of a way, all else is unequivocally straightforward. A purify and transparent interface creates it easy to restrict sold GIF, PNG or JPG images and review a formula while a collection interface processes mixed files during unequivocally high speeds.

Unfortunately, what you’re not removing here is lossless compression. RIOT is some-more about shortening a series of colours in your image, re-encoding JPEGs with a revoke peculiarity value, and so on.

Despite this, a module still managed to make some of a exam images intensely larger. (You’ll need to check RIOT’s outlay delicately before we use it.)

The module still did well, though, in sold with a GIFs, that it managed to revoke by an normal of 42.8%. Its impassioned configurability meant RIOT deserves a closer look.

14. ScriptJPG

Platform: Windows

ScriptJPG is one of a some-more obsolete packages here, being radically usually a Windows book that acts as a front finish to several authority line tools. Drag and dump your JPGs onto a script, name your application options (either lossless or a sold JPEG peculiarity setting) and ScriptJPG will cut down a images for you.

That’s a plan, anyway. For some reason, tt didn’t work as advertised with a JPG web graphics and never even displaying a starting menu. We’ve no thought because and, of course, one problem with ScriptJPG’s rather elementary proceed is we don’t get any useful blunder messages.

We were means to exam a package on a JPEG photos and here a book was sincerely successful. Its lossless application choice cut a distance of a images by roughly 10%.

If you’re a technical form afterwards ScriptJPG might be of interest. You can diagnose problems as they stand adult and maybe revise a script, customising a application parameters to fit your possess needs.

If we cite an easy life, though, we’d hang with one of a GUI-based equivalents. There are copiousness of some-more absolute alternatives and, of course, they’re many easier to use, too.

15. ScriptPNG

Platform: Windows

As you’ve substantially already guessed from a name, ScriptPNG is a cousin of ScriptJPG: a Windows collection record that uses 4 utilities to cut your PNG files down to size.

As with ScriptJPG, it’s a unequivocally bare-bones approach. Drag and dump your images onto a record and a authority prompt opens with 9 probable application options. Choose a one we need and a module is off, crunching any record in spin (and replacing a strange images with a output, so make certain we have a copy).

An additional problem we had is that pngout.exe kept crashing. The book didn’t seem to care, yet we were forced to manually tighten a blunder dialog any time it happened.

For all that, application formula were impressive. Our PNG Web Graphics mislaid adult to 40.1% of a bulk.

We still cite a some-more full-featured optimisation tool, on balance. But there’s no doubt that a scripting proceed does give we a outrageous volume of control. If we don’t like something ScriptPNG does, or wish to supplement some new apparatus or option, usually revise a record accordingly.

16. Smush.It

Platform: web

Most picture application web services are heavily restricted, yet Yahoo’s Smush.It is a singular exception. You’re singular to files of adult to 1MB in size, yes, yet differently a complement will upload as many images as we need. There’s no registration, no comment creation, no daily quotas. Images are crunched them with a accumulation of tools, permitting we to download a formula in a ZIP file.

If there’s one problem with this proceed it’s that you’re unequivocally removed from application collection themselves. You can’t configure or tweak them in any way. The formula we see are what we get and there’s zero whatsoever we can do to change them.

That’s something of an emanate with JPGs as Smush.It usually managed to revoke a exam images by around 1%.

PNG application was some-more effective during 35.3%, though, while a GIFs mislaid an considerable 23.9% (the best lossless application opening here).

On change we still cite a leisure and configurability of a internal tool, yet if a preference of an online use suits your needs afterwards Smush.It might be a essential choice.

17. TinyPNG

Platform: web

Similar to Smush.It, TinyPNG is a giveaway web use that can optimise images for you. Just drag and dump your files onto a web page, it’ll restrict them during speed and yield links for downloading.

The complement has some annoyances. The 2MB record distance extent isn’t too bad, yet we can usually upload 20 files during one time, and we contingency afterwards manually download any one in turn, that isn’t a good idea.

TinyPNG also takes a clearly some-more lossy proceed to application than many of a other collection here by compliance a palette to revoke (sometimes dramatically) a series of colours in use.

Unsurprisingly, this pays off in terms of a tender figures, with a use compressing a PNG web graphics by a strong 48% – a best in this test. And in many cases you’ll find it unequivocally formidable to mark any disproportion between a source images and dense versions.

The best of a lossless collection also managed application rates of over 40%, though. And so if picture peculiarity is your tip priority – or we usually don’t wish to always be comparing graphics, perplexing to see if there’s any disproportion – afterwards one of TinyPNG’s improved competitors might be a improved deal.

18. Trout’s GIF Optimizer 2.3

Platform: Windows

Trout’s GIF Optimizer is another unequivocally tiny and unstable application tool. No designation is required; usually unzip a download and it’s prepared to go.

Features are a tiny limited, though. As you’ll theory from a name, a module is usually about GIF application and there are no tellurian pattern options of seductiveness (although we can manually optimise a palette of sold images in a accumulation of ways).

Still, this does during slightest make Trout’s GIF Optimizer unequivocally easy to run. Just import your selected photos, a distance rebate achieved for any picture is displayed right divided (it’s unequivocally fast), and we can save them with usually a few clicks.

But, unfortunately, this doesn’t make for quite considerable application results: a GIF web graphics usually shrank by an normal of usually 16.7%.

If you’re happy to take a time to manually try a colour palette options for sold images afterwards Trout’s GIF Optimizer might be value a try, yet many people are expected to grasp improved formula with another tool.


After many hours of testing, benchmarking and generally putting a contenders by a paces, one doctrine was unequivocally clear: picture application unequivocally can learn poignant and unequivocally inestimable results.

Our PNG exam files were customarily reduced by 30 to 40%, for instance, and even a JPEGs could be cut in distance by 16-18%. This was all regulating lossless compression, so there’s no rebate in picture quality; a files demeanour accurately a same, yet usually bucket some-more quickly.

The accurate formula you’ll see might change considerably, of course. But if you’ve not attempted anything identical before afterwards it’s unequivocally value holding a best of a programs for a hearing usually to see what they can do for you.

Which collection should we choose? FileOptimizer delivered a best all-round lossless opening underneath Windows, with an glorious 42.2% application rate for a exam PNG files, unequivocally means JPG and GIF results, and some other useful options thrown in (PDF compression, for instance).

But if a module doesn’t work for you, PNGGauntlet and ScriptPNG also delivered good PNG compression, and ImageOptim for a Mac managed useful JPEG and GIF compressions rates.

And, nonetheless we found a exam web services to be reduction available to use, don’t order them out entirely. PUNYpng was a best lossless JPG compressor here, while Smush.It trampled over a GIF competition, and both could be a good assistance in slicing your possess web graphics down to size.
