How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a SRT from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your LRC the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Drop a file, get a converted file.

Why convert SRT → LRC

What this conversion is actually for

Reverse direction: if you already have subtitles for a music video as SRT and want to publish them as a karaoke-style LRC file (for use in Spotify lyric apps, karaoke players, or lyric databases), convert here. SRT end times are dropped (LRC only marks the start of each line) and multi-line cues are joined into one LRC line per timestamp.

A real example

You captioned a music video in SRT for YouTube and now want to contribute the lyrics to a karaoke library that expects LRC. Convert and submit.

Troubleshooting

Multi-line SRT cues come out as one long LRC line.

Intentional. LRC is a one-line-per-timestamp format. If you need to split a long line for display, edit the .lrc in any text editor and add a second timestamp for the wrap point.

About SRT and LRC

SRT, SubRip Subtitle

SRT is the simplest subtitle format: a numbered list of cues, each with a `HH:MM:SS,mmm --> HH:MM:SS,mmm` timestamp and one or more lines of caption text. Originated in 2001 from the SubRip ripping tool and became the universal default — every video player (VLC, MPV, mpv, every web video framework), every subtitle editor, and every video platform reads SRT.

How to open

Any text editor (it's just text). VLC autoloads `<videoname>.srt` if it's next to the video file. Subtitle editors like Subtitle Edit, Aegisub, and EditSubs provide visual timing tools.

FAQ

Common questions

Is this SRT → LRC converter really free?

Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert SRT to LRC?

Universal subtitle format for video players and editors. File interchange. The most common reason to convert is compatibility, LRC works in places where SRT doesn't, or vice versa.

How do I open a SRT file in the first place?

Any text editor (it's just text). VLC autoloads `<videoname>.srt` if it's next to the video file. Subtitle editors like Subtitle Edit, Aegisub, and EditSubs provide visual timing tools.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
