Upload an MP3 and get a clean, accurate transcript instantly. No sign-up, no software, no watermark.
This free MP3 to text converter turns any MP3 recording into readable, editable text. It is
made for the everyday audio that piles up on our devices: voice memos, recorded interviews,
call recordings, dictated notes, and downloaded podcast episodes. Drop the file in, wait a
few seconds, and read the transcript. Switch to the timestamped view to find a specific
moment, copy the text in one click, or download a plain .txt file.
No account, no app, and no watermark. Language is detected automatically, so you never touch a settings menu. It is the fastest way to stop retyping recordings and start working with the words instead: search them, quote them, summarize them, or paste them straight into your notes.
It suits a wide range of people: podcasters drafting show notes, journalists clearing a backlog of interviews, students turning recorded lectures into study notes, researchers pulling quotes from field audio, and anyone sitting on a phone full of voice memos they never replay. Accuracy follows the recording, so a clean, close capture reads almost word for word, while a noisy or distant one usually needs a quick edit afterward. Your MP3 stays private the whole time, held behind an access token only you receive and deleted automatically after 30 days.
For the sharpest result, start with a clean recording. If your MP3 has room hum or background chatter, run it through the background noise remover first, or even out an uneven recording with the audio normalizer. Need captions rather than plain text? The SRT generator builds subtitle files with timestamps. About to record? Confirm your setup with the mic test.
MP3 files are capped at 100 MB and free use is limited to 30 requests per hour, which covers everyday transcription with room to spare. Need longer files, batch processing, or higher limits? See pricing.
Drag your MP3 into the box above, or click to choose the file. It uploads, transcribes automatically, and returns the full text in seconds. From there you can copy it, switch to a timestamped view, or download it as a .txt file. There is nothing to install.
Not much. Speech recognition cares far more about clarity than about bitrate, so a clean 96 kbps voice recording transcribes about as well as a 320 kbps one. Where bitrate matters is if the file was compressed so hard that words are already hard to hear, in which case accuracy drops for humans and machines alike.
Yes. Voice memos from your phone, call recordings, and dictation exports are ideal for this tool. If your phone saves memos as M4A rather than MP3, that works too. For the clearest result, hold the phone close and record somewhere quiet.
The free tool accepts MP3 files up to 100 MB, which is roughly two hours of typical spoken audio. Longer recordings should be split into parts first, or run through our API, which is built for long-form and batch transcription. See the pricing page for the details.
Yes. Your file travels over an encrypted connection and is held behind a private access token that only you receive, so nobody can browse to it. Files are deleted automatically after 30 days, and we never sell recordings or use them to train models.
Yes. The language is detected automatically, so Spanish, English, and dozens of other languages just work. If you mostly transcribe Spanish MP3s, use our Spanish version at MP3 a Texto for native copy and support.
