MP3 to text
Convert MP3 audio to text
Upload an MP3 recording and extract its spoken English into an editable transcript. Keep the plain text or use the word timing to create subtitle files.
How it works
- Choose an MP3 file no larger than 200 MB.
- Run English speech recognition on the audio.
- Review the result and download TXT, SRT, or WebVTT.
After transcription, download plain text, SRT subtitles, or WebVTT captions from the same result.
Best fit
Use this page when the source is specifically an MP3: voice notes, interview exports, podcast excerpts, lectures, narration takes, or compressed field recordings.
Uploads use private temporary storage and generated text is not stored in the database. Review the privacy policy before using sensitive material.
What to expect from this conversion
MP3 input
Both spoken-word and mixed-audio MP3 files can be submitted, but loud music, compression artifacts, and distant voices can reduce recognition quality.
Transcript output
The result stays editable in the browser and can be copied or downloaded as TXT. Timed words also support SRT and WebVTT export.
Temporary processing
The file uses private temporary storage for transcription and is deleted after processing. Generated transcript text is not stored in the database.
