Yahoo! Smush.it is a famous tool for web designers. It’s often considered as the best image optimization tool, but it has some limitations. One of the promising open source alternative is Trimage Image Compressor.

Conclusions from The Test
- Smush.it won most the times (11 for Smush.it and 6 for Trimage)
- Smush.it can compress GIF files while Trimage can’t
- Trimage can compress large files, Smush.it only can process up to 1+ MB file sizes.
Although the total result sizes for Trimage is 8,488,015 is smaller compare to Smush.it 8,840,422 but if we exclude the large file (that can’t compressed by Smush.it), Trimage will lose (Trimage 5,300,179 vs Smush.it 5,226,997).
For getting smaller result Yahoo! Smush.it is the winner, but if it fails to compress or give 0 saving you may try to use Trimage Image Compressor.
