MP3 to Text Converter: Free Online Transcription
Turn any MP3 into an editable transcript with timestamps. It runs in your browser, so your audio is never uploaded to a server.
How to convert MP3 to text
Add your file
Click Choose MP3 file or drop the audio onto the box.
Pick language and accuracy
Leave language on Auto detect, or select it for better results.
Convert
Press Convert to text. The first run downloads the speech model once, then it is cached.
Copy or download
Edit the transcript, copy it, or save it as TXT or SRT subtitles.
Why use this MP3 to text converter?
Typing out interviews, podcasts, lectures and voice notes by hand takes hours. This tool uses an AI speech model (OpenAI Whisper) that handles accents, background noise and many languages, and produces a transcript you can search, quote, translate or publish as an SEO-friendly article.
Private by design
Audio is processed inside your browser. Nothing is sent to our server.
Accurate AI
Choose the Accurate or Best model for clear punctuation and fewer errors.
Timestamps and subtitles
Export an SRT file for YouTube, Vimeo or video editors.
Works on every device
Use it on desktop, tablet or phone with a modern browser.
Tips for the best transcript
Use clear audio with little background noise, select the spoken language instead of Auto detect, and choose the Accurate model. For long recordings, keep the tab open until conversion finishes. Always proofread names and technical terms.
Frequently asked questions
Is the MP3 to text converter really free?
