About these formats
TTML
TTML is a W3C XML standard for timed text. It supports rich styling, regions, animations and accessibility metadata, and is the format Apple Music ships synchronised lyrics in (TTML 2 with Apple's iTunesTimedText profile). It also underpins SMPTE-TT for broadcast captions and is exported by professional subtitling suites such as EZTitles, Subtitle Edit and FAB.
Full TTML guide →SRT
SRT was created for the SubRip ripper utility and is now the lingua franca of subtitling: every video player, every YouTube uploader, every editing suite reads it. Each cue is a numbered block of plain text bracketed by a start→end timestamp written as `HH:MM:SS,mmm`. Styling is generally limited to a few HTML-style tags (<i>, <b>, <font>).

Questions
How do I convert TTML to SRT?
Paste your TTML into the input box, or open a file from your device. The converter runs in your browser and produces SRT instantly. Click Download to save it.
Is this free?
Yes — no signup, no credits, no upload. Conversion happens entirely on your device, so the file never leaves your browser.
Are timestamps preserved?
Yes. Timestamps round-trip from TTML into SRT with millisecond precision.
What if my TTML has styling or positioning?
Only what both formats can express survives a conversion. SRT keeps the timings and the text; formatting that SRT has no equivalent for is dropped rather than approximated.
