LRC to SRT Converter
FileFlip converts LRC to SRT 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 SRT?#
- 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 SRT 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 SRT file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting LRC to SRT lose quality?#
No. Subtitle cues are text, and converting LRC to SRT rewrites the same timings and the same lines in the target's syntax. Anything SRT 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 SRT actually does to the file#
Converting LRC to SRT 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 SRT file?#
An SRT file numbers each caption in order and gives it a start and end timecode measured in hours, minutes, seconds and milliseconds, with the line or lines of dialogue printed underneath and a blank line separating one caption from the next.
Use SRT when the file needs to open in the widest possible range of players and sites and doesn't need positioning or styling.
Convert away from SRT when the destination needs something SRT cannot hold, such as WebVTT's on-screen cue positioning or ASS's karaoke timing and typesetting.
LRC to SRT questions people ask#
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.
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.
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.
What program opens an SRT file?
An SRT file opens in essentially any video player, including VLC, and in dedicated subtitle editors like Subtitle Edit and Aegisub. Because it's plain text, it also opens in Notepad or TextEdit, though it will display raw timecodes rather than a preview.
