Questions

How do I convert SSA to VTT?

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

Is my SSA 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 SSA files at once?

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