LRC to SRT converter
Convert LRC subtitles to SRT. Drop in a file or paste the text — the conversion runs inside your browser and nothing is sent to a server.
LRC vs SRT
The synced-lyrics format for music players: foobar2000, Poweramp, car head units and karaoke apps all read it. Each line simply starts with an [mm:ss.xx] tag. There is no end time and no multi-line cue: one timestamp, one line. SRT, by contrast: The most widely supported subtitle format: VLC, Premiere Pro, DaVinci Resolve, PowerDirector and virtually every player read it. Each cue is a number, a `HH:MM:SS,mmm --> HH:MM:SS,mmm` line, the text and a blank line. Milliseconds are separated with a comma.
How to use it
Choose a subtitle file or paste the text, then press Convert. Files saved as Shift_JIS or UTF-16 are detected and decoded automatically, and the output is always UTF-8. You can pick CRLF or LF line endings so the file opens cleanly in Windows editors too.
What changes in the conversion
LRC has no end times, so each line ends where the next one begins (the last line gets four seconds). An [offset:] tag is applied if present.
Frequently asked questions
Are my subtitle files uploaded anywhere?
No. The conversion runs as JavaScript inside your browser, so the file contents never cross the network. That matters for subtitles, which are effectively the script of a video that may not be public yet. The page also keeps working offline once loaded.
Is it free? Do I need an account?
It is completely free with no sign-up and nothing to install. There are no conversion limits and no file-size cap beyond your browser memory.
Can it read a file that shows up as gibberish?
Yes. Shift_JIS, EUC-JP, UTF-16 and UTF-8 with a BOM are detected automatically. If you already pasted garbled text, load the original file in the Fix subtitle encoding tool instead.
Will the timings drift?
No. Times are held as whole milliseconds internally and rendered in the SRT notation on output. Rounding errors do not accumulate.
