Convert MP3 to text in your browser
Podcasts, lectures, interviews and phone recordings are often stored as MP3. Drop an MP3 here and TidyTranscribe will decode it, run speech recognition on your device and show the text as it is recognised.
Long MP3 files are processed in segments, so you can start reading before the whole file is finished. Export the result as plain text for notes, or as SRT if you need timestamps.

FAQ
Is there a size limit for MP3 files?+
There is no fixed limit. Very long recordings take longer and use more memory, so for files over an hour a desktop computer with Chrome or Edge is recommended.
Does it work with other audio formats?+
Yes. Besides MP3 it accepts M4A, WAV, OGG, OPUS, FLAC and WEBM audio, as long as your browser can play the file.
Is it really free?+
Yes. Transcription runs on your own device, so it costs us nothing and is free for you.
Is my audio uploaded?+
No. The model is downloaded once and cached; your files never leave your browser.
Which browser works best?+
A recent Chrome or Edge on desktop uses your GPU and is fastest. Other browsers fall back to CPU mode.
How long can a file be?+
There is no hard limit, but long files take longer on slower devices. Start with the Fast model.
