Frequently asked questions

How do I convert a WEBM file?

Drop the file into the window, pick the target format, and download the result. No account required.

Do I need to install anything?

No. It runs in your browser. A Windows installer is available separately if you prefer one.

What if the format I want isn't listed?

Every engine's capabilities are merged into a single graph, so unlisted pairs are chained automatically through intermediate formats along the least-lossy route.
