Not All PNG Compressors Are Created Equal
SEPTEMBER 15, 2011
Not All PNG Compressors Are Created Equal. Here's two versions of a Jing logo from one of our press releases. If the PNG compressor doesn't optimize color depth, or uses non-aggressive DEFLATE compression it can produce PNG's that are up to 90% bloat. Optimizing the PNG's in the Camtasia Relay PC recorder resulted in a ~7% (302KB) file-size reduction. Keep in mind that the Relay recorders are relatively small apps and use a relatively small number of PNG's.
