OptiPNG recompresses PNG files to decrease their size. This process is lossless, meaning the contents of the images are exactly the same once decompressed. OptiPNG can work on several formats, including #TIFF and #GIF, outputting an optimized PNG version of whatever input is given. OptiPNG can also verify the integrity of an image and recover metadata.
