Convert audio to text — free and unlimited

Drop in almost any audio file — MP3, WAV, M4A, FLAC, OGG — and get an editable transcript with timestamps. There is no minute cap, no account, and no queue. Your files are never uploaded — everything runs on your device.

Most transcription sites limit the free tier because every minute costs them server money. This one runs the speech model inside your own browser, on your own hardware, so there is nothing to meter. The engine is open source, and after the first model download it works offline too.

How to transcribe audio

  1. Pick your audio file

    Drag it into the box above or click Choose file. Common audio formats are supported directly — no conversion needed first.

  2. Wait for the one-time model download

    On first use the speech model (about 80 MB) downloads into your browser cache. It stays cached, so later transcriptions start immediately.

  3. Watch the transcript stream in

    Long recordings are processed in chunks, so text starts appearing before the file is finished. Progress and a time estimate are shown throughout.

  4. Edit and export

    Click any segment to fix a word, then download the result as TXT, SRT, VTT, or JSON — or copy the plain text.

Why this converter is different

Actually unlimited

No minute caps, no monthly quota, no premium tier. Because inference runs on your device, a three-hour file costs us the same as a three-second one: nothing.

Private by design

The audio is decoded and transcribed locally. Privacy here is not a policy promise — uploading your file is simply not part of the design.

No signup, no nagging

Open the page, drop a file, leave with your transcript. No account, no email, no trial countdown.

Frequently asked questions

Is it really free without limits?
Yes. The transcription runs in your browser on your hardware, so there is no per-minute server cost for us to pass on. The site is ad-supported, which keeps the tool itself free.
Which audio formats work?
Anything your browser can decode: MP3, WAV, M4A/AAC, FLAC, and OGG cover almost everything. Video files work too — the audio track is extracted automatically.
How accurate is the transcription?
It is powered by OpenAI’s open-source Whisper model, one of the most widely used speech-recognition models available. Accuracy depends on audio quality, accents, and background noise, so we won’t quote a single percentage — try it on a real file and judge the result yourself.
Which languages are supported?
The standard multilingual model handles about 100 languages and can auto-detect which one is spoken. There is also a translate option that outputs English regardless of the source language.
Does it work offline?
After the first visit, the model and the app are cached by your browser. As long as the page loads, transcription itself needs no internet connection at all.
Where does my file go?
Nowhere. It is read locally, decoded locally, and transcribed locally. Your files are never uploaded to any server — ours or anyone else’s.
