How mp3 to srt works
Upload your MP3
Drop in the MP3 – Pepys prepares the audio automatically, no setup required.
Pepys times the cues
AI transcribes the speech and breaks it into cleanly timed subtitle lines with start and end timecodes.
Download your .srt
Grab the .srt to pair with your video in any editor or player – or export VTT, TXT, Markdown, DOCX, PDF, or JSON too.
Plenty of workflows start from audio: you've got the MP3 of a talk, a voiceover, or a podcast, and you need an .srt to caption the matching video. Pepys does it in one step – upload the MP3 and get back a standard subtitle file with every line timed to when it's spoken, ready to drop onto your timeline.
The subtitles sit on top of an accurate, timestamped transcript, so the timing is honest and the words are right. It works in 99+ languages with auto-detect, there's nothing to install, and you pay only for the minutes you transcribe – credits never expire and we never train on your audio.
Clean paragraphs. No more um's and ah's.
The left is what Pepys hands back – logical paragraphs with the filler stripped out, punctuated and readable. The right is the raw, one-line-per-segment dump most transcribers leave you with.
um so yeah everyone keeps telling you to like lead with your best line right but uh honestly if you give away the whole answer in the first second you know there's basically no reason for anyone to keep watching so the hook isn't kind of the smartest thing you say it's like a loop you open that they need to close and um that's the part that actually keeps people around

Mp3 to srt – questions, answered
How do I convert an MP3 to SRT?
Upload your MP3 on this page – the first 60 minutes are free, no card. Pepys transcribes it and gives you a timed .srt subtitle file to download in minutes.
Will the SRT timing line up with my video?
If the MP3 is the same audio as your video, the .srt cues line up out of the box. The timecodes come straight from the transcription, so each line is timed to when it's spoken.
Can I get the subtitles in another language?
Yes – language is auto-detected across 99+ languages, and you can translate the finished transcript before exporting it as an .srt.
Can I also get a VTT or plain transcript?
Yes. The same transcript exports to VTT for the web, plus TXT, Markdown, DOCX, PDF, and JSON – choose whatever your workflow needs.
