Not All PNG Compressors Are Created Equal
SEPTEMBER 15, 2011
Not All PNG Compressors Are Created Equal. The image on the right is less than 1/2 the size of the original image on the left. 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. But know that file size isn't the only thing affected.
