Free audio to text converter for MP3, WAV, M4A and video files
This free audio to text converter turns recordings into text you can read, search and edit. Drop in an MP3, WAV, M4A, OGG, WEBM or MP4 file, choose the spoken language, and transcribe audio to text directly in your browser. Unlike most online transcription tools, your file is never uploaded: Whisper Tiny runs locally on your device and returns copyable text plus TXT, SRT and VTT downloads.
Add your audio
Drag an MP3, WAV, M4A, OGG, WEBM or MP4 file into the drop zone, or click to browse. The audio is loaded straight into the page — it is never sent to a server.
Pick a language and transcribe
Choose the spoken language or leave it on Auto-detect, then press Transcribe. The Whisper Tiny model downloads once (about 40 MB), then converts your speech to text on your own CPU.
Copy or download the transcript
Read the transcript, copy it to your clipboard, or download it as a .txt file — or as .srt / .vtt subtitles with timestamps for video captioning.
Convert audio to text free
Point the tool at any recording with speech and get editable text back. No manual typing, no scrubbing through the timeline, no expensive transcription service.
Transcribe audio to text with Whisper AI
Recognition runs on OpenAI's Whisper Tiny model, a genuine neural speech-to-text network, running locally through WebAssembly instead of on a server.
MP3, WAV, M4A and more
Voice memos are usually M4A, podcasts and music are usually MP3, and recordings are often WAV. All work, along with OGG, WEBM and the audio track of MP4 videos.
Subtitles with timestamps
Beyond plain text, export SRT and VTT subtitle files with timecodes, ready to drop onto a video for captions — all generated in your browser.
Free and unlimited
A genuinely free audio to text converter: no account, no credits, no watermark and no per-minute cap. Transcribe as many files as you like.
Works offline after the first run
Once the model is cached by your browser, transcription needs no network at all. The page keeps converting audio to text on a plane or behind a firewall.
Interviews and meetings
Turn a recorded interview, meeting or lecture into searchable text you can quote, summarize or paste into notes — without sending sensitive conversations to a cloud service.
Voice memos and dictation
Convert a quick voice memo, a dictated idea or a phone recording into text you can edit, so you never have to retype what you already said out loud.
Subtitles and captions
Generate SRT or VTT subtitles from a video's audio track to caption podcasts, tutorials or social clips and make them accessible.
MP3 to text
The most common audio format for podcasts, music and downloads. Convert an MP3 to text without converting the file first.
WAV to text
The uncompressed format most recorders and DAWs produce. WAV is lossless, so it usually gives the cleanest, most accurate transcription.
M4A to text
The format iPhone Voice Memos and most phone recorders save in. Transcribe an M4A voice note straight from your device.
OGG, WEBM and MP4
Browser and app recordings are often OGG or WEBM, and MP4 videos carry an audio track. All are decoded and transcribed without a separate conversion step.
A tiny model, on purpose
Transcription runs on Whisper Tiny, the smallest model in OpenAI's Whisper family: roughly 40 MB of quantized weights. That size is what makes browser transcription realistic — a large Whisper model would be gigabytes and could never be shipped to a visitor's browser. The model runs through ONNX Runtime Web on WebAssembly, so the same neural network that would normally run on a server runs on your own CPU instead. Whisper Tiny trades some accuracy for speed and size; clear speech transcribes well, while heavy accents, background noise or overlapping voices are harder for any tiny model.
Multilingual by design
Whisper Tiny is a multilingual model (not the English-only tiny.en). It recognizes speech in dozens of languages, including English, Chinese, Japanese, Korean, Spanish, French, German, Italian, Portuguese, Russian, Arabic, Hindi and many more. Choose the spoken language from the selector for best results, or let Whisper detect it automatically.
No upload, no server
There is no upload endpoint and no API call carrying your audio. The file is decoded by the page and passed to a model running in the same browser tab.
Nothing is stored
Because the audio never reaches a server, there is nothing to retain, log or delete. Close the tab and every trace of the recording and its transcript is gone.
Safe for confidential recordings
Interviews, therapy sessions, legal calls and private meetings can be transcribed without them ever crossing a network — which most online transcription tools cannot honestly claim.
Only the model is downloaded
The one thing that crosses the network is the model itself, downloaded to your browser. Data flows toward you, never away from you.
Most audio to text tools upload your file
The usual online transcription service posts your recording to a server, runs speech recognition there, and returns the text. That means your audio sits on someone else's disk, subject to their retention policy. Here, the recording stays on your device.
No sign-up, no per-minute limits
Cloud transcription services meter free use with minute caps, monthly quotas or a sign-up wall, because every minute costs them compute. Browser transcription spends your CPU, so there is nothing to meter.
Honest about accuracy
A tiny model trades some accuracy for the ability to run locally at all. On clear speech it is very usable; on noisy audio, strong accents or overlapping speakers, expect to fix some words. For studio-grade accuracy you may still want a larger model.
01How do I convert audio to text?+
Drop your audio file into the box at the top of this page, pick the spoken language (or leave it on Auto-detect), and click Transcribe. The speech recognition model reads the audio and produces a transcript you can copy or download as .txt, .srt or .vtt. No account or install is needed.
02Is this audio to text converter free?+
Yes, completely free and unlimited. There is no account, no credit system, no watermark and no cap on how many files or minutes you transcribe. The transcription runs on your own computer, so there is no server cost to pass on to you.
03Do you upload my audio to a server?+
No. This is the main difference from most online audio to text converters. Your file is decoded directly by the page and processed by a model running inside your browser tab. The audio never travels over the network, so there is nothing for us to store or hear.
04Which audio formats can I transcribe?+
MP3, WAV, M4A, OGG, WEBM and MP4, plus AAC and FLAC. That covers voice memos, podcasts, recorder output, browser recordings and the audio track of videos. Files up to 200 MB are accepted.
05What languages does it support?+
Whisper Tiny is multilingual and recognizes speech in dozens of languages, including English, Chinese, Japanese, Korean, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Polish, Ukrainian, Indonesian, Vietnamese, Thai, Malay, Hindi, Arabic, Turkish, Hebrew, Greek, Czech, Swedish, Danish, Finnish and Norwegian. Choose one from the selector or let it auto-detect.
06Which speech recognition model does this use?+
Whisper Tiny, the smallest multilingual model in OpenAI's Whisper family — about 40 MB of quantized weights. It runs through ONNX Runtime Web on WebAssembly, entirely inside your browser. We use the multilingual checkpoint, not the English-only tiny.en.
07Can I get subtitles with timestamps?+
Yes. Besides plain text, you can download the transcript as an .srt or .vtt subtitle file with timecodes, ready to attach to a video for captions. The timestamps are produced by the model as it transcribes.
08Why is the first transcription slower than the rest?+
The first run downloads the Whisper model (about 40 MB) and compiles the WebAssembly runtime. After that the model is cached by your browser, so every later file is transcribed immediately, with no download at all.
09How accurate is it?+
Whisper Tiny is the smallest model, so it favors speed and size over maximum accuracy. On clear, single-speaker speech it is very usable; on noisy audio, strong accents or overlapping voices, expect to correct some words. Picking the exact spoken language instead of Auto-detect usually improves the result.
10Does it work offline?+
After the first run, yes. Once your browser has cached the model there is no further network activity, so the page keeps converting audio to text with no connection at all.

Transcribe audio to textBecause audio is processed entirely in your browser and is never transmitted or stored, using this tool does not create a data transfer to us. That makes it a good fit for recordings covered by GDPR, HIPAA or internal confidentiality rules — but you remain responsible for handling the resulting transcript appropriately.
