OGG and OPUS are efficient audio formats used by WhatsApp and Telegram voice notes, games, and open-source apps. Many players and editors don’t open them, so converting to MP3 makes them playable anywhere.

Frequently asked questions
Is my file uploaded to a server?
No. The converter (FFmpeg compiled to WebAssembly) runs inside your browser, so the file never leaves your device. That also means there is no upload wait, even for big videos.
How do I save a WhatsApp voice note?
On Android, press and hold the voice message and tap Share to save it. On iPhone, press and hold, choose Forward, then use the Share icon and Save to Files.
Can I get the text of the voice note instead?
Yes. Use the WhatsApp voice message transcriber to turn it into text.
