FAQ

Q: Does my image get uploaded to a server?
A: No — compression happens entirely in your browser; nothing leaves your device.

Q: Which format is best?
A: WebP usually gives the smallest files with good quality (supported on most modern browsers). JPEG is widely compatible. PNG is lossless (not good for photos if size matters).

Q: What if compression fails?
A: Try a different format or lower quality. Very large images may take longer or cause memory issues in older browsers.
