About this timestamp formatter

Different platforms format chapter timestamps differently. YouTube wants `0:00 Title` with the first marker at exactly 0:00. Apple Podcasts wants its own ID3 CHAP frames. Spotify shows whatever you put in the description. This tool takes one canonical paste and outputs each platform's preferred format so you don't have to copy-paste-edit per place.

Pure text manipulation — no audio required. Type or paste your timestamps, pick a target, copy the result.

Timestamp formatter FAQ

Why does YouTube need 0:00 as the first chapter?

YouTube's chapter UI requires the first marker at exactly 0:00 with at least 3 markers in total, and each chapter must be at least 10 seconds long. The formatter warns if your input violates these rules.

Does this make ID3 chapter markers?

No — for embedding actual ID3 CHAP frames into the MP3 file (so podcast apps show jump points), use our Chapter Markers tool. This is just text formatting.

Can I include speaker names?

Yes — anything after the timestamp gets passed through. `12:34 Guest 1: opening pitch` works fine.

Is the data sent anywhere?

No. We don't analyse, index or keep your data.
