What is an SSA file?
SSA (SubStation Alpha) is the predecessor to ASS and shares the same [Events] / Dialogue structure, along with support for custom styling. Like ASS, it's less universally supported than SRT, so converting is often necessary before using SSA subtitles elsewhere. SSA files are less common today than ASS, but they still turn up in older subtitle archives and some legacy fansubbing and karaoke projects, which is why this converter supports both formats through the same reliable parser.
How to convert SSA to SRT
- 1Upload your .ssa (or .ass) file by dragging it in or clicking "Choose file".
- 2The tool reads the [Events] section and converts each Dialogue line.
- 3Timestamps are converted from centiseconds to SRT's millisecond format.
- 4Preview the result, then copy it or download the .srt file.

- Make older SubStation Alpha subtitles compatible with modern players.
- Upload subtitles to a platform that only accepts SRT.

FAQ
- What's the difference between SSA and ASS?
- ASS (Advanced SubStation Alpha) extended the original SSA format with more styling and positioning options. Both share the same Dialogue line structure, so this tool handles them with the same reliable engine.
- Will timestamps be accurate after conversion?
- Yes, timestamps are converted from SSA's centisecond format to SRT's millisecond format with full precision.
- Are styling tags removed?
- Yes, override tags used for color, position or font are stripped since SRT doesn't support them, but the dialogue text is kept intact.
- Is my file uploaded anywhere?
- No, everything is processed locally in your browser.
- Can I convert a .ssa file with this tool, or only .ass?
- Both. This tool accepts .ssa and .ass files through the same engine, since the Dialogue line structure that matters for conversion is shared between the two formats.
