J I C is a Javascript Image Compressor using HTML5 Canvas & File API that allows you to compress your jpeg & png images before uploading to the server (100% client-side and no extra libraries required!)
I can't seem to get it to actually compress a png file on the demo page. I tried the attached file with the default compression ratio of 30 and the file size went from 2765KB for the source file to 4089KB for the "compressed" file. I also tried different compression ratios but they didn't seem to change anything in the output file.
