Frequently asked questions
Does this upload my subtitle file?
No. Parsing and conversion run locally in your browser.
What happens when converting LRC to a subtitle format?
LRC normally stores start times only. The tool uses the next lyric timestamp as the cue end, with a short fallback duration for the final cue.
Are ASS styles preserved?
No. This lightweight converter preserves timing and text, but emits a simple ASS style when ASS is the target and removes ASS override tags when converting to plain subtitle formats.
