## FAQ

### What quality should I choose?

70% to 85% usually halves the file size with no visible loss. For less demanding uses 50% to 60% works too.

### Why is PNG compression weak?

PNG is lossless, so browsers cannot compress it lossily. Convert PNGs to WebP or JPG (when transparency is not needed) for big savings.

### Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

### Do I need to sign up or pay?

No. The site is completely free, requires no account, has no usage limits and adds no watermarks.
