pngcrush is an excellent batch-mode compression utility for PNG images. Depending on the application that created the original PNGs, it can improve the file size anywhere from a few percent to 40% or more (completely losslessly). The utility also allows specified PNG chunks (e.g. text comments) to be inserted or deleted, and it can fix incorrect gamma info written by Photoshop 5.0 as well as the erroneous iCCP chunk written by Photoshop 5.5.

Version 1.7.34 introduced a bug in which a file was opened for each trial compression but never written or closed. After a system-dependent number of trials, pngcrush was unable to open a file for the next trial and exited. This release fixes that bug.
