FAQ
Can image compression be completely lossless?
PNG can often be optimized without visible loss, but JPG and WebP usually trade a small amount of detail for a much smaller file. The goal is no noticeable quality loss for the final use.
Which format should I use for websites?
WebP is usually the best first choice for websites. Use JPG when you need older compatibility and PNG when transparency is required.
