Questions

How do I convert M2TS to MKV?

Drop your M2TS file on this page, or choose it. Anyfile converts it on your device in a moment and the MKV downloads straight away. To change it first, open it in the video editor.

Is my M2TS 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.

Can I convert several M2TS files at once?

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