SRT to ASS

Turn a plain SRT into a basic ASS/SSA file you can open in Aegisub or a fansub workflow.

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

Output is a basic editable ASS (default style). Fancy effects are not invented — add them later in a tool like Aegisub.

How it works

Start styling in Aegisub
You have timing and text in SRT and want an ASS file to open in Aegisub before adding styles, karaoke, or positioning.
Fansub / encode pipeline entry
A simple SRT needs to enter a soft-sub or encode workflow that expects ASS as the working format.
Keep a default-style ASS for later
You do not need effects yet — only a valid ASS container with a default style so you can decorate it later.

Please noteCueConvert creates a basic ASS (default style). Add karaoke, positioning, or effects later in a tool like Aegisub.

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?

Output is a basic editable ASS with a default style. Fancy effects are not invented.

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 ASS.

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 ASS back to SRT?

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