ImageOptim is a front-end (GUI) for set of tools for optimisation of PNG and JPEG images.

Optimisation makes files smaller (in terms of disk space) by finding optimal compression parameters and by removing unneccessary information, like file comments, EXIF tags and color profiles.

Indispensable. I'm looking into getting Codekit and if so I might not need this. But It's been a great tool that always shave off some more with quality retained or make images generally publishable.

Does a good job of reducing file sizes, but I've encountered several instance where it won't complete its task, indefinitely showing the cog icon next to the images being processed.
Also, the dev, for some reason best known to himself, has decided to allow the Sparkle updater to download updates without user consent, and without offering a user-facing option allowing the user to disable it. Out of the dozen or more apps I have that use the Sparkle framework, this is the only one to be so coded. After conversing with him by email and presenting what I thought were good reasons to include such a feature, the dev still refuses to do so.
Hence, only 3 stars.

"Now code-signed. (Purchased 1-year Developer ID from Apple to avoid blocking of independent software in OS X 10.8 Mountain Lion and 10.9 Mavericks.)"

Please donate to the programmer, to help them pay Apple's developer tax:

Non-code signed apps are not "blocked" in 10.8 (I can't comment on 10.9). All such apps can be permitted to launch by changing the setting in System Preferences > Security & Privacy > Allow Applications downloaded from: Anywhere. Or, you can allow such apps on an individual basis by leaving the aforementioned setting at its default and opening them by right-clicking and choosing, "Open" from the contextual menu. You will be prompted to authenticate as an admin user, and this app will now be permitted to launch like any other.

PRO: Easy to use, reduces file sizes notably, drag & drop, FREEWARE!
CONS: Slow for bigger images, ruins CMYK images, sometimes you need to do a 2nd pass to reduce even more (should be done automatically).

This is my feedback to help improve this great app! =)

Excellent and flexible image compression tool. Use it regularly for all my web projects.

You can't import (flat) Photoshop-files, no preview... and it takes time. ImageOptim will strip the icc-profile (good for websites, bad for photographers). You will save 5-9% of original file size.
No lost of quality.

Useful, usable, quick, actively developed … and free. A serious tool.

The two things I would add are:
1. A progress for the current batch
2. Some stats (can be in Console log) to say which algorithms were selected most often.

I might spend the time to figure out how but I'm sure the original dev could do it quicker.

Handled 5000+ png tiles like a pro. This app tries a variety of algorithms several times to find the optimal compression method and settings for each png (of jpg or gif).

Check out the preferences and you'll see why this is more valuable than simple guis that just pipe through a single command line tool.
