What happens when converting ASS to LRC?

Advanced SubStation Alpha content is parsed into a unified millisecond timeline before being exported as LyRiCs. Valid timing and subtitle text are preserved.

LRC output stores only each subtitle's start time because the format does not support end times.

Complex ASS / SSA style tags and positioning are removed while visible text and timing are converted.

Source file format

ASS · Advanced SubStation Alpha

ASS, or Advanced SubStation Alpha, is an enhanced successor to SSA. It can precisely control subtitle fonts, colors, positions, animation, and karaoke effects.

File structure: ASS files are organized into sections such as Script Info, V4+ Styles, and Events. Subtitle cues are usually stored as Dialogue lines that reference predefined styles.
Common uses: ASS is commonly used for anime subtitles, visual subtitle effects, complex typesetting, karaoke, and video workflows that require precise presentation control.
Conversion notes: ASS can express much more styling than SRT, LRC, or TXT. When converting to a simpler format, this tool preserves visible text and timing but not complex styling, positioning, or animation.

Target file format

LRC · LyRiCs

LRC, short for LyRiCs, is a synchronized lyrics format. A timestamp before each lyric line lets music players reveal lyrics as a song progresses.

File structure: A typical LRC line uses a [minutes:seconds.fraction] lyric-text structure. Files may also contain title, artist, album, and offset metadata, and one line can carry multiple timestamps.
Common uses: LRC is commonly used by music players, desktop lyrics displays, mobile music apps, karaoke lyrics, and tools for creating synchronized song lyrics.
Conversion notes: Standard LRC normally stores only the start time of each lyric line. When converting to a subtitle format, an end time must be inferred from the next valid lyric timestamp.
