Load an MP3, WAV, or M4A file and export the result as plain text, SRT subtitles, or WebVTT captions.

FAQ
- Is my audio uploaded to a server?
- No. All processing runs locally in your browser. Your audio file never leaves your device.
- What audio formats can I transcribe?
- You can transcribe MP3, WAV, and M4A files. These cover most recordings from phones, voice recorders, and editing apps.
- What output formats are supported?

- Is it free?
- Yes. The Audio Transcriber is free to use with no account, no watermarks, and no time limits.
- Why is a desktop browser recommended?
- Speech recognition is computationally heavy. A desktop or laptop has more memory and processing power, so transcription is faster and more reliable than on a phone.
- Does it work offline?
- Once the page and the speech model have finished loading, transcription can run without an internet connection.
- How accurate is the transcription?
- Accuracy depends on audio quality, background noise, accents, and speaking pace. Clear recordings produce the best results, and you can edit the text before exporting.
