LRC to SSA Converter
FileFlip converts LRC to SSA entirely inside your browser, using FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an LRC file to SSA?#
- Drop your LRC file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to SSA and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the SSA file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting LRC to SSA lose quality?#
No. Subtitle cues are text, and converting LRC to SSA rewrites the same timings and the same lines in the target's syntax. Anything SSA has no syntax for, such as positioning or styling, is dropped rather than degraded.
Is it safe to convert LRC files online?#
Yes, because nothing is uploaded. FileFlip converts LRC files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What LRC to SSA actually does to the file#
Converting LRC to SSA runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, rewrites the cues as text in the target's syntax, keeps cue durations.

What is an LRC file?#
An LRC file pairs a song's lyrics with a [mm:ss.xx] timestamp at the start of each line, meant to sit alongside an audio file of the same name so a music player can display the lyrics in time with playback rather than caption a video.
Use LRC to display synchronized lyrics alongside a song in a music player, not as a caption track for video.
Convert LRC to a video subtitle format only when the lyrics are being repurposed as on-screen captions, such as for a lyric video.
What is an SSA file?#
An SSA file is a SubStation Alpha v4 script split into a Script Info section, a Styles section defining named formatting templates, and an Events section holding every line of dialogue with its timing, style reference and positioning, the same three-section layout ASS later extended.
Use SSA only when working with an existing v4 script or a tool that hasn't moved to ASS; a new styled subtitle is better authored directly in ASS.
Convert SSA to ASS to pick up transparency and the fuller set of override tags, or convert to SRT when the destination can't render styled subtitles at all and losing the styling is acceptable.
LRC to SSA questions people ask#
What is an LRC file used for?
An LRC file synchronizes a song's lyrics with its audio, showing each line at the moment it's sung. It's a music-player sidecar file, named to match its audio track, not a subtitle format for video.
Why won't my video player show an LRC file as subtitles?
LRC was built for music players to display lyrics against a song, so most video players don't look for or parse it as a caption track the way they would an SRT or VTT file. Converting the lyrics into a video subtitle format is the reliable way to caption a video with them.
Can LRC highlight lyrics word by word?
The base LRC format only times whole lines, but its extended A2 variant adds a <mm:ss.xx> timestamp before each word inside a line, letting a compatible player highlight lyrics word by word for karaoke-style display.
Is SSA the same as ASS?
No, but they're the same lineage. SSA is SubStation Alpha version 4, and ASS (Advanced SubStation Alpha) is version 4+, an extension of the same three-section format that added an alpha channel for transparent colors, a numpad alignment system and karaoke tags SSA doesn't have.
