Common questions
Is styled conversion lossless?
No. This tool preserves cue text, multiline Unicode text and millisecond timing for a limited compatible subset. It normalizes line endings and timestamp notation. Advanced formatting and metadata are rejected rather than silently discarded; check appearance in your target player.
