Great tool that is easy to use. A must for anyone looking to optimize the size of files (particularly for the web).

This file optimization tool is the best and most complete you will find on the Internet! Because it optimizes better than any other program I know, and it does not matter whether JPG, PNG, PDF, it swallows just about all file types! In addition, it is constantly supplied with updates and further developed for years! There are many optimization levels, from low to high optimization, and thus from low to high compression rate. It can also compress many files losslessly if needed, and it can also remove metadata if needed. It can compress all file types mixed in one go! No other open source program has so much distros and features inside and is so damn awesome too! I am really excited about this masterpiece of innovative programming art!

It is the most comprehensive suite of optimization that I've seen to this date. It's better than e-Mage, PNGGauntlet, PNGOptimizer, Caesium, CaesiumPH, and RIOT. It is great and I do not hesitate to give it five stars. However, it is not perfect. As of this writing, it is difficult to resize the app's columns. Also, the app stores its settings in an awful place, i.e. the root of the user profile. (It should have stored it in a proper subfolder in the AppData\Roaming folder.) But, in comparison to its competitors, these are minor issues.

Very-very useful software for me!

Vraiment un super outil, j'ai eu de très bon résultat pour réduire des pdf fait via smartphone qui pouvait atteindre jusqu'à 10Mo. Traitement par lot, garde le même nom des fichiers. Excellent travail, merci d'avoir choisi une licence libre.
