Personally, I like the psydk PNGOptimizer https://psydk.org/pngoptimizer for PNG files and FileOptimizer for JPEG files. The latter will work on all kinds of files but is exceptionally slow on PNG files. You can mess with the settings so it doesn't take so long but I don't bother. Source: almost 2 years ago
