Convert OPUS and OGG to MP3
Convert WhatsApp and Telegram voice notes (.opus, .ogg) to MP3 that plays on any device. Free, private, no upload.
Drop files here or click to choose
Your files stay on this device. Nothing is uploaded.
WhatsApp saves voice messages as OPUS inside an OGG container, which many players and email clients cannot open. MP3 fixes that. The conversion runs on your phone or computer; the recording is never uploaded.
How it works
- Drop .opus or .ogg files.
- Convert (128 kbps is ideal for voice).
- Download the MP3.
This tool runs entirely in your browser. Your files are never uploaded, so there is no size limit and it works offline once loaded.
Frequently asked questions
Is it really free and private?
Yes. Everything runs in your browser with open-source code; nothing is uploaded. No account, no watermark, no file-size limit other than your device's memory.
How do I get the .opus file from WhatsApp?
Long-press the voice note and choose Share or Export, then save it to Files (iPhone) or your Downloads folder (Android). Then drop it here.
