Frequently Asked Questions

Which video formats are supported?

The tool converts between MP4 and WebM, the two formats browsers can re-encode natively. Output depends on your browser's capabilities.

Is there a file size limit?

There is no fixed limit, but very large videos take longer and use more memory since everything is processed locally in your browser.

Are my videos uploaded to a server?

No. Conversion runs entirely on your device, so your videos never leave your computer or phone.

Why did my conversion fail?

Some browsers limit which codecs they can encode. If MP4 output fails, try WebM, or use a desktop browser like Chrome for best results.
