YOGA Image Optimizer is a free tool to convert and optimize JPEGs, PNGs and WebP image files. Simply Drag & drop images, click on “Optimize”, and you're done!

With YOGA, you will be able to save about 30 % of space on JPEGs and 20 % on PNGs. On WebP images, you will only save few percents... but converting a JPEG to a lossy WebP can reduce image size to a half and converting a PNG to a lossless WebP can save you 35 % on average.

Please note that image optimization can be slow and may require a lot of RAM, especially for JPEGs. For example, the JPEG encoder needs 300 MB of RAM and 3 min per Mpix (PNG and WebP encoders are less resource hungry).
