This free online WebP compressor converts your lossless PNGs or high quality JPEGs into lossy WebPs with the smallest filesize possible.
There are a lot of articles about online image compression tools in the net, most of them are very superficial. Usually they end with a simple: "It generates smaller pictures, so it's got to be better."
Learn why such statements are most of the time meaningless, understand the technical background, and find out which tool you should use as of today.
A small but nice update at Compress-Or-Die. compress-or-die.com/analyze now shows the estimated quality for all quantization tables contained in a JPEG. To improve the privacy for all of us, I now also use Matomo instead of Google Analytics and have completely removed Addthis.
