SyncMySubsConvert SRT to ASS
Turn a SubRip .srt file into an Advanced SubStation Alpha .ass file with a clean default style. Drop it below and it converts instantly in your browser.
From plain text to a styled format
SubRip (.srt) holds only plain text and timing, while Advanced SubStation Alpha (.ass) can carry fonts, colours, positioning, and effects. Converting .srt to .ass wraps your subtitles in a minimal, valid .ass file with a single default style, which you can then restyle in an editor like Aegisub. Your timing and text come across unchanged, so it is a safe starting point for adding styling later.
FAQ
What styling will the .ass file have?
A single default style, white Arial with an outline. Converting from .srt can't invent styling that was never there, so it gives you a clean, valid .ass base that you can restyle in an editor like Aegisub.
Does the timing or text change?
No. Your cue timing and text are copied across exactly. Only the container format changes, from SubRip to Advanced SubStation Alpha.
Is anything uploaded?
No. Everything runs locally in your browser, with no server and no account, and it works offline.
