OGG and Opus: great codecs, awkward files

OGG is the container the open-source world standardised on: Vorbis for music, Opus for voice. Opus is what WhatsApp, Telegram, Signal and Discord use for voice messages, and it is technically superior to MP3 at low bitrates. The trouble is playback. Export a WhatsApp voice note and try to play it in an email client, an old media player, a car stereo or a transcription service, and it often refuses — which is why "convert ogg to mp3" is a search people make right after "how do I save a voice note".

Converting rewraps the audio as an MP3 that plays on every device made this century. The speech is untouched, the length is identical, and the file becomes something you can attach, forward or drop into any app without a second thought.

MP3 or WAV: choose by what happens next

The default output is a 192 kbps MP3 — deliberately generous for voice notes, which are usually recorded at 16-32 kbps Opus, so the MP3 stage never subtracts anything audible. The result plays anywhere and stays small: a five-minute voice note is about 7 MB as MP3.

Switch to WAV when the audio is going into an editor, a court-admissible archive, a transcription workflow that prefers PCM, or anything that will be processed further. WAV is uncompressed 16-bit PCM, so nothing is lost after the decode — at the cost of roughly ten times the size. Mono voice notes stay mono, which halves that cost.

• WhatsApp / Telegram voice notes → MP3 to forward, attach or keep
• Podcast or music in OGG Vorbis → MP3 for a car or old player
• Recorded interviews → WAV for editing or transcription
• Game or app audio assets in OGG → whichever the target software accepts

Getting the file out of the messaging app first

The conversion is the easy part; the fiddly step is exporting the voice note. On WhatsApp, long-press the message, choose Forward or Share, and send it to Files, Drive or your email — the result is an .ogg or .opus file. On Telegram, use Save to Downloads. Desktop WhatsApp lets you download the note directly. Once you have the file, drop it on this page.

If the file has an .opus extension rather than .ogg, it is the same thing in a different wrapper and converts just the same. Files that will not decode at all are usually not audio: a .bin or .enc file exported from an encrypted chat backup is not a playable recording, and no converter can open it.

Converted in the tab, never uploaded

Every step runs inside your browser, using the WebAssembly and Canvas APIs your device already ships with. No file is uploaded, no copy is kept, and nothing sits in a queue on a server waiting to be deleted — which is also why the tool keeps working with the network disconnected.

Voice notes are private by nature — a message from a friend, a doctor's instructions, a recorded conversation — and the last place they belong is on a converter's server. Here the browser decodes the Opus or Vorbis audio with its own engine and encodes the MP3 or WAV in JavaScript. The file is read from your disk and written back to your downloads folder; nothing in between touches the network.

That also removes every artificial limit: no daily quota, no queue, no sign-up. Convert one voice note or a whole folder of them, one after the other, on the phone they were received on.
