MP3 to SRT, locally
MP3 is the most common way audio reaches you — a podcast export, a voice memo, a lecture recording. This tool reads it in your browser and writes out an SRT you can use anywhere captions are accepted.
Because nothing is uploaded, there is no queue and no daily cap. Run it as many times as you like.
FAQ
Does the audio quality of the MP3 matter?
Yes. Low bitrate files and recordings with background noise produce more errors, so budget a few minutes to proofread the output.
How long does a 10 minute MP3 take?
Around 16 minutes on a typical desktop. The estimate is shown before it starts.
Can I get a plain transcript too?
Yes — TXT is included alongside SRT and VTT, and the zip contains all three.
Do I need to register?
No account, no email, no quota.
