ImageOptim does a great job, but it should be noted that transparency (especially with a gradient fade) is a tough job for any image optimizer. By reducing the size of your file, you’re potentially losing out on some of the quality in more demanding areas of the image. It’s best to test before committing your site to any of these solutions. JPEGmini is clean, quick, and remarkably consistent. It can reduce images by up to 5x, though the typical reduction we’ve seen hovers around 1.6x, which is still pretty impressive given the quality retention on either side of the optimization process. Just drag your JPEG files into the window and watch them shrink. JPEGmini only works with JPEG files, so you’re out of luck with this tool if you wish to optimize PNGs or GIFs. The original files are replaced with optimized copies, though you can configure it to create a second file in order to preserve the original. Unlike ImageOptim, JPEGmini is commercial software.

There is a free (Lite) version available which gives you basic optimization tools.

You’ll probably want to throw down the $20 for the full version to make the most out of your experience. #IMAGEOPTIM FASTEST SETTING FULL VERSION# Kraken is one of those solutions that is just too handy to leave off the list. Boasting better compression rates than Yahoo! (also a great alternative), its Web interface makes it handy in a wide variety of situations. You can use the free Web interface to great effect, though there is a paid version that gives you the ability to upload larger source files (up to 4 MB). Kraken’s price plans are a little confusing. You’re paying a monthly subscription for a set number of images and source maximums. The reason it made its way to this list is simply because of its Web interface and reasonably good performance. You can choose between lossless and lossy output files and throw together an optimized site from virtually any computer with a browser.

The tool uses a predefined threshold and determines how far it can compress.Ĭhime back in with your final results/preference. From experience, the feature I think is unique is the automatic one click processing. Notice how it doesn't compare itself to other software, it just promotes itself. Most hate it because it tries too hard to sell itself when other free open source tools also exist and do the same. I also read on a few other forums users' opinions of jpegmini. Extremely handy! I only wish it showed more of the tool's internal options. I used to have a script for compressing PNGs with PNGOUT but now RIOT allows to process them in batch. I tried the tool the user posted on this thread but it produced some weird results, on a few images it cropped the picture by a few pixels. Messing with the Chroma and Luma channels is something nearly every jpeg compressing tool does and I'd like to know which one I'm using to compare their features. I liked RIOT very much but I wish it showed which external tools it uses besides the PNG ones. Hopefully being open source means others will step up with with cool new ideas. I'm sure there are a ton of optimizations to be made, but to be totally honest my math and C programming skills are not the best. if it's a picture of clouds then lower the quality slightly and if it's an intricate building then increase the quality a bit. One thing I would like to add is some measure of overall image complexity, e.g. what's the average pixel value, how do the pixels vary, what's the relationship between the original variance and the reference block variance, etc. The algorithm I use is SSIM, which works by measuring relationships between pixels in 8x8 blocks, e.g.

I haven't read the patents (and won't due to possibly tainting my own code with information from them). JPEGmini actually uses some custom patented algorithm for perceived image quality. That's much better than throwing away too much.

Luckily it errs on the side of caution and throws away less data than JPEGmini. I think the groups of solid colors are problematic. Thanks! Feel free to contribute the bat file if you think it'll be useful for others.
