Ship ASS/SSA as WebVTT for web players. Timing and plain text are kept; ASS effects are not.

Files stay in your browser. Nothing is uploaded to a server.

Only timing and plain text are kept. ASS/SSA styles, positions, and effects cannot be carried into SRT/VTT/SBV.

How it works

Fansub / Aegisub → course or site player
Finished ASS needs to run on an HTML5 player, LMS, or CMS that only accepts VTT.
Deliver dialogue without ASS chrome
You keep a styled ASS master, but the public web version should be plain timed text as VTT.
Preview on the web before release
Quickly get a VTT from ASS to test in a browser player without rebuilding the whole site pipeline.

Please noteASS styles and effects are stripped. VTT receives timing and readable text only.

Are my files uploaded?

No. Conversion runs in your browser. CueConvert does not require an account and does not upload subtitle files for conversion.

Are ASS styles / effects preserved?

No. When converting to SRT / VTT / SBV we keep timing and plain text only, and we tell you upfront.

Does a batch cost extra?

No. A batch is free, with no account, same as one file. Successes download as one zip. Failures are listed on their own.

Will timing and text stay accurate?

We aim to keep readable text and timing. After convert, use the preview to check cues, then download VTT.

What if Chinese text looks garbled?

We try to detect file encoding automatically. If it still looks wrong, re-save as UTF-8 locally, then drop the file again.

Can I convert VTT back to ASS?

Yes. Use the reverse link below this page when that route is live, or open it from the Tools menu.
