Convert SubStation Alpha (.ssa) subtitles to SRT online. SSA is the older sibling of ASS and is common in older anime releases and DVD-era subtitle files. It shares the same styling model, which means it also fails to play on many modern devices. This converter extracts the clean dialogue and timing and outputs a universally compatible .srt file.
SSA (SubStation Alpha) was the original scripted subtitle format from 1997. ASS (Advanced SubStation Alpha) later extended it with more styling and effects. Both are text-based, style-rich formats. SRT (SubRip) is the older, simpler format that stores only plain text and timestamps. Because SRT is supported everywhere, every TV, phone, console, and media server, converting SSA to SRT is the reliable way to make older subtitle files play anywhere.
The tool parses each SSA dialogue line, reads its start and end time, extracts the actual spoken text, and rebuilds it as an SRT cue. All SSA styles, margins, alignment values and effect fields are ignored, since SRT cannot represent them. The result is a clean, universally playable subtitle file with timing that matches the original.
If you are digging out old anime or DVD-era subtitle files, SSA is common. Modern players like Plex and Jellyfin can partially handle it, but smart TVs and consoles often cannot. Converting to SRT once means you never have to think about compatibility again. The tool also handles legacy encodings like Shift-JIS and GBK, so subtitles in Japanese, Chinese and Korean convert without mojibake.
SSA (SubStation Alpha) is the original format from 1997. ASS (Advanced SubStation Alpha) is its successor with expanded styling. Both convert to SRT the same way, styling is stripped, text and timing are kept.
Yes. The converter handles both .ssa and .ass files, plus VTT, SMI, MicroDVD SUB, MPL2 and ZIP archives.
Yes. Start and end timestamps are copied exactly from each SSA dialogue line. SRT uses the same millisecond timing model, so sync is preserved.
Most TVs and streaming devices only support SRT. Convert the SSA to SRT with this tool and it will play without issues.
Yes. All conversion happens locally in your browser. Nothing is uploaded to any server.
Convert SSA (SubStation Alpha) subtitles to SRT when a player or media library needs a simpler, broadly supported text format.
Supported input or output formats for this workflow are .ssa input and SRT output. The exact controls on the page determine which options apply.

SSA is the older style-rich format related to ASS. Conversion extracts dialogue and timestamps while dropping style and effect fields.
Older encodings can affect CJK text, so inspect the downloaded SRT when working with archived subtitle releases.

Open this tool, select the relevant file, choose the available SSA to SRT converter options, and download the generated result. The page keeps the workflow in the browser rather than requiring an installed editor.
Use the formats listed in the tool description and picker. .ssa input and SRT output Formats outside that list may be rejected or need conversion first.
The tool is built for browser-side processing. Your file is selected by the browser and the result is downloaded locally rather than being described as a server upload.
No. Subtitle tools create or modify subtitle output only. The video itself is not edited, re-encoded, or downloaded by this workflow.
Open the downloaded file with a text editor or your video player. Confirm that cues are present, timestamps make sense, and the filename matches the video when automatic loading is useful.
Before archiving the SRT, play it against the first and last ten minutes of your video. If every cue is off by the same amount, or the gap widens over time, send the file through our subtitle sync tool to fix the offset or rescale the timeline — conversion preserves timestamps, so any mismatch was already in the source or comes from a frame-rate assumption.
To understand what the conversion kept and dropped, compare the formats in SRT vs VTT vs ASS subtitle formats, then follow how to add subtitles to a video for loading the SRT in your player of choice.
