Where OPUS files come from

WhatsApp and Telegram voice messages, Discord recordings and many browser recordings use the OPUS codec, sometimes with a .ogg name. It sounds clear at a small size, but older phones, cars, editing apps and upload forms often reject it.

Saving voice messages

For a voice note still inside WhatsApp, the WhatsApp voice message guide shows how to get the file out first.

Questions and answers

Does converting OPUS to MP3 lower the quality?

Slightly, since both are compressed. At 128 kbps or more, speech sounds the same.

Can I convert several OPUS files into one MP3?

Yes. Use the Audio Joiner to put them together.

Why is my OPUS file so small?

OPUS is very efficient for voice: a minute of speech can be under 100 KB. The MP3 will be bigger at the same clarity.

Can I join several OPUS voice notes into one file?

Yes. Open them all in the Audio Joiner, put them in order and save one MP3.
