Drop in the audio file
MP3, M4A or WAV · up to 2 GB or 3 hours
or drag and drop it anywhere hereA subtitle-ready workflow
Start from audio, finish with a cue file.
Subtitle timing is treated as a deliverable. Untimed text remains useful, but it is not converted into invented cues.
Review before export
Readable captions need more than accurate words.
Check fast exchanges, names and long sentences against the recording. The editor keeps each cue close to its source so the exported file is easier to trust.
Upload the source and let the batch workflow create the private project.
Replay the first minute and any section with quick speaker changes.
Use SRT broadly or WebVTT for an HTML video player.
Questions, answered
MP3 to SRT questions
Can I convert any MP3 directly to SRT?
When the speech provider returns verified sentence timing, the project can export SRT or VTT. Without timing, it remains available as TXT or Markdown.
Can I edit the captions before downloading?
Yes. Review the transcript against playback and correct the text or cue boundaries before exporting.
Does this download audio from a URL?
No. Upload an audio file you own or have permission to process.
Is the original file public?
No. Projects remain private to the account and exports are files rather than public transcript pages.
