    Choose your audio

    Select an AAC, FLAC, M4A, MP3, OGG, WAV, or WebM file up to 20 MB.

  2. 02

    Start transcription

    Choose automatic language detection or provide a language hint, then securely upload the file for processing.

Audio to text FAQ

Frequently asked questions about audio transcription

Learn about uploads, supported formats, languages, output files, and retention.

Is my audio uploaded?

Yes. After you start transcription, the selected file is securely uploaded to Cloudflare R2 and processed with Cloudflare Workers AI. Editing tools elsewhere continue to process files locally.

How long is my audio stored?

Source audio expires 24 hours after upload and is removed asynchronously. Text results remain available long term for TXT, SRT, and WebVTT downloads. Edited drafts remain in this browser until you reset them or clear browser storage.

Which files can I transcribe?

Audio to Text accepts AAC, FLAC, M4A, MP3, OGG, WAV, and WebM files up to 20 MB.

Which languages are supported?

Automatic detection is the default. You can also hint English, Chinese, Spanish, French, German, Japanese, Korean, Portuguese, Italian, Russian, Arabic, or Hindi.

What can I download?

Download a UTF-8 TXT file, an SRT file, or a WebVTT file containing timed captions.

Can I refresh while transcription is running?

Yes. Once upload completes, this browser remembers and restores the current task after a refresh.
