Questions

How do I convert SRT to ASS?

Drop your SRT 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 SRT 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 SRT files at once?

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