Questions

How do I convert MTS to WEBM?

Drop your MTS file on this page, or choose it. Anyfile converts it on your device in a moment and the WEBM downloads straight away. To change it first, open it in the video editor.

Is my MTS file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Will I lose quality?

WEBM is a compressed format, and Anyfile saves at high quality, so the difference is very hard to notice.

Can I convert several MTS files at once?

Yes. Drop them together and you get one ZIP with every WEBM inside.
