Audio to Text
Transcribe audio to text free online. Upload MP3, WAV, M4A and more - get an accurate transcript with one-click copy and download. No signup, powered by Whisper AI.
What is Audio to Text?
Turn any audio recording into accurate text in your browser - no signup, no software to install. Upload an MP3, WAV, M4A, AAC, FLAC, OGG, or WebM file and the tool transcribes the speech using OpenAI's Whisper model (via faster-whisper), auto-detecting the spoken language. When it's done you get a clean transcript you can copy to your clipboard with one click or download as a .txt file. It's ideal for turning voice notes, interviews, meetings, lectures, and podcast clips into searchable, editable text. Audio is processed securely and not stored - and the whole thing is completely free.

FAQ
Audio to Text — Frequently Asked Questions
Everything you need to know before you start.
Is this audio-to-text tool free?
Yes, transcription is completely free. There's no signup required for casual use, though a generous daily limit applies and signing in raises it. No watermarks, no credit card.
What audio formats are supported?
MP3, WAV, M4A, AAC, FLAC, OGG, and WebM are all supported, up to 10 MB per file (roughly 5-7 minutes of audio). Most voice notes, interview clips, and meeting snippets fit comfortably.
How accurate is the transcription?
It uses OpenAI's Whisper model (via faster-whisper), which is highly accurate for clear speech across many languages. Accuracy drops with heavy background noise, overlapping speakers, or very strong accents - clean audio gives the best results.
Which languages are supported?
Whisper supports 90+ languages and detects the spoken language automatically, showing it as a label above the transcript. You don't need to select a language manually.
Is my audio stored or shared?
No. Your file is sent securely to the transcription service, processed in memory, and not saved or shared. The transcript stays in your browser until you copy or download it.
Why does transcription sometimes take a while?
Transcription runs on a free CPU server, so processing time scales with audio length - longer clips take longer. The very first request after a period of inactivity can also be slower while the service wakes up.
