Getting voice notes out of WhatsApp

On Android, voice notes are in the WhatsApp “Voice Notes” media folder; on iPhone and Android you can also share a voice message and choose “Save to Files”. Then choose the file here.

Browser support

Chrome, Edge and Firefox read Opus everywhere. Older Safari versions cannot; use Chrome on those devices.

Limitations

Up to 60 minutes and 500 MB per file.
Which input formats open depends on your browser: Chrome and Edge read the most formats.

Privacy

Files you choose are read into your browser’s memory and processed on your device; they are not uploaded to a server. Temporary download links are released after use, and the offline cache never stores your documents. More about privacy and limits.

Frequently asked questions

Are my voice messages private?

Yes. They are converted in your browser and never sent to a server.

Are my files uploaded?

No. The audio is decoded and processed in your browser, so recordings and videos never leave your device.

Is it free?

Yes – free with no signup, no watermark and no daily limit.

How long can a recording be?

Up to 60 minutes per file (and 500 MB). The whole recording is held in your device’s memory while it is processed, so very long files need a computer rather than an older phone.
