Download the converted copy and keep the original separately.

Limits to know

Browser support can vary for newer or device-specific image formats.

FAQ

Common questions about browser-only file conversion.

Are files uploaded to a server?No. Selected files are processed in the browser, and converted results are not stored on a server.

What should I do if processing is slow?Lowering FPS, output size, color count, or processing duration reduces browser memory use and processing time.

Can I use it on mobile?Yes, but desktop browsers are more stable for large files.
