Questions

How do I convert VTT to ASS?

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

Is my VTT 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 VTT files at once?

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