About Opus to MP3
Voice messages from chat apps and recordings from many web tools are saved as Opus. It's an excellent format, but some players and editors don't support it yet.
This converter decodes the Opus audio in your browser and encodes it as MP3. Voice messages are personal, so they never leave your device.
For voice messages and speech, 128 kbps is plenty; choose 192 or 320 kbps for music. Opus is very efficient, so the MP3 is usually larger than the original even at the lowest setting. That's normal, and it's the price of playing everywhere.
Files ending in .opus and .ogg files with Opus sound inside both work. You can drop several voice messages at once and download them together as a ZIP. If your browser can't decode Opus, which is rare today, the page tells you clearly.
Each MP3 keeps the length of the original recording, so a two-minute voice message stays two minutes. It keeps working when you lose signal, as soon as the page has loaded.
