When to Convert
Common scenarios where this conversion is useful
Repurposing anime song lyrics for music players
Anime opening and ending songs often have ASS subtitle files with lyrics. Converting to LRC lets you load those lyrics into music players like foobar2000 or Dopamine.
Extracting dialogue for karaoke apps
If you have ASS files with timed text content, converting to LRC lets karaoke software display the lines in sync with audio playback.
Building lyric databases from existing subtitle archives
Large subtitle archives in ASS format can be batch-converted to LRC to populate music lyric databases and apps that rely on the lightweight LRC format.

Frequently Asked Questions
LRC is a simple text format for syncing song lyrics to audio. Each line starts with a bracketed timestamp like [01:23.45] followed by the lyric text. It is widely supported by music players and karaoke apps.
No. LRC does not support styling. ASS styling tags (\N, \b, \i, \c and others) are stripped, and only the plain text content and timing are carried over to LRC.
ASS positioning tags like \pos and \move are stripped during conversion. LRC has no concept of screen positioning — all lines appear as sequential text.
LRC is designed for audio/lyrics players, not video players. For video subtitle use cases, you are better off converting ASS to SRT or VTT. LRC lacks the timing precision and feature set needed for video subtitles.
foobar2000, Winamp, Dopamine, MusicBee, Quod Libet, and most Android music player apps support LRC. Apple Music and Spotify use proprietary formats but many third-party iOS players support LRC.
Yes. Files are uploaded over HTTPS and automatically deleted from the server after the LRC is ready for download.
LRC timestamps use [MM:SS.xx] format where xx is centiseconds (1/100th of a second). ASS timestamps use centiseconds as well, so timing precision is maintained during conversion.
Subtitle files are plain text and typically very small. The 50 MB server limit is not a practical constraint for ASS files.
Yes. ChangeThisFile supports LRC to ASS conversion for round-tripping between formats.
Yes. All dialogue lines are extracted regardless of which style track they belong to. The style information is stripped, and lines are ordered chronologically in the output LRC file.
