LRC to WebVTT Converter
FileFlip converts LRC to WebVTT 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 WebVTT?#
- 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 WebVTT 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 WebVTT file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting LRC to WebVTT lose quality?#
No. Subtitle cues are text, and converting LRC to WebVTT rewrites the same timings and the same lines in the target's syntax. Anything WebVTT 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 WebVTT actually does to the file#
Converting LRC to WebVTT 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 a WebVTT file?#
A VTT file is a WebVTT text track: a WEBVTT header followed by timed cues, each with a start and end timecode and one or more lines of text, optionally carrying position, size and CSS-style settings that place and format the text on screen.
Use WebVTT for subtitles served to an HTML5 <video> element, where the browser reads the track natively and honors its cue positioning and styling.
Convert WebVTT to SRT when the destination is a player or device outside the browser that only expects plain, unpositioned captions.
LRC to WebVTT 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.
What is a WebVTT file used for?
A WebVTT file supplies the captions or subtitles for an HTML5 video, loaded through the <track> element so the browser displays them without any extra plugin. It's the format browsers expect natively, the way SRT is the format most desktop players expect.
