How to convert an MP3 to text
Have an MP3 of a podcast episode, a lecture or a voice memo and need the words in writing? This converter transcribes MP3 files, and other sound files like M4A and WAV, straight in your browser. There is nothing to install and nothing to upload: the speech recognition runs on your computer, and you get an editable transcript you can copy or save as a text file or Word document.
- 1
Choose your MP3
Drop the MP3 onto the page or click to pick it. M4A from an iPhone voice memo, WAV from a recorder, and AAC files work the same way. Files can be up to an hour long.
- 2
Start the transcription
The first time, the tool asks before loading its speech model. After that it starts straight away. It skips silence and music without speech, then writes down every word it hears.
- 3
Correct anything it misheard
Read the transcript under the player. Click a word to fix it, or replace a misspelled name everywhere at once. Click a time to listen to that part again.

Save the text
Copy it to the clipboard, or download a TXT file or a Word document. It starts as clean text; turn on Timestamps to add a time to each paragraph.
Good uses for MP3 transcripts
- Podcast show notes and blog posts. Start from the transcript instead of a blank page, and pull quotes for social posts. Search engines can’t listen to audio, so a written version helps people find an episode.
- Lectures and classes. Turn a recorded lecture into notes you can search and highlight before an exam.
- Voice memos. Ideas recorded on a walk become text you can paste into a document or a to-do list.
- Meeting recordings. Check exactly what was agreed, with the time it was said.
- Accessibility. A transcript lets people who are deaf or hard of hearing follow an audio-only episode.
Sound quality matters more than the format
MP3 is a compressed format, but even a modest 64 kbps file holds plenty of detail for speech recognition, so there is no need to convert it first. What matters far more is the recording itself: a microphone close to the speaker, a quiet room and no background music give the cleanest transcript. If a podcast has a music intro, the tool simply finds no words there.
If your audio is inside a video, you don’t need to extract it: Video to Text reads the sound straight from MP4, MOV and WebM files. And if you want an MP3-sized file from a video for other uses, Extract Audio saves the soundtrack as M4A or WAV.
Long recordings
Files up to 60 minutes are transcribed in one go. On a recent laptop in Chrome, Edge or Safari, an hour of audio takes roughly 8 to 15 minutes; Firefox is slower. For a longer recording, cut it into parts with Trim Video, which opens long files and cuts them without re-encoding, then transcribe each part. Your corrections are remembered in this browser, so you can come back to a file later.
Your audio stays on your computer
Online MP3 converters usually upload your file first. That is a problem for private recordings: a therapy session, a legal consultation, a family voice note or an unreleased episode. This one loads the speech model into your browser and does the work there, so the MP3 never leaves your device. The How it works page explains how to check that for yourself.
Frequently asked questions
Can I convert an MP3 to text for free?
Yes. Transcription, editing and downloads are free, with no account and no limit on how many files you transcribe.
Do I need to convert my MP3 to WAV first?
No. MP3, M4A, WAV and AAC files can be transcribed as they are.
How long does an MP3 transcription take?
A few seconds for a short voice memo. An hour-long file takes roughly 8 to 15 minutes in Chrome, Edge or Safari on a recent laptop, and longer in Firefox.
Is there a file size limit?
The limit is length, not size: up to 60 minutes per file. Split longer recordings with Trim Video first.
Does it work with podcasts that have music?
Yes. Music without speech is skipped. Speech over loud music is harder to recognize, so check those parts.
Is my MP3 uploaded to a server?
No. The file is read and transcribed in your browser and never leaves your device.
