FAQ
Frequently asked questions
Which format compresses best?
JPG usually gives the smallest file for photos. WebP is often smaller still at the same visual quality. PNG stays lossless but compresses less — use it only when you need pixel-perfect output or transparency.
Is Compress Image free?
Yes, and there is no sign-up, watermark or daily limit — everything runs in your browser rather than on a metered server.
