Why convert OGG to OPUS?
You received a WhatsApp, Telegram or Discord voice message (.opus/.ogg) and it will not open on your computer, car stereo or editing software. OPUS solves the problem.
How to do it, step by step
- Drop your OGG fileinto the area at the top of the page (or several files at once). On mobile, tap the area and pick the file from your apps.
- Check the output format: OPUS is already selected. For music, 192 kbps is transparent for most listeners and 320 kbps gives the maximum. For voice (memos, podcasts, lectures), 128 kbps is more than enough and halves the file size.
- Start the conversion.The FFmpeg engine loads once (≈ 10 MB), then each file is processed in a few seconds without leaving your device.
- Download your OPUS, directly or as a .zip if you converted several files. The name and metadata (title, artist, cover art) are preserved.
The OGG format (Ogg Vorbis)
OGG Vorbis is a free and open format, a competitor to MP3, widely used in video games, on Wikipedia, Spotify (internally) and on Linux. Good quality, but poor compatibility on Apple devices and many car stereos.
- Completely patent-free
- Good quality
- Small
- Not natively played by iPhone/iTunes
- Few compatible car stereos
The OPUS format (Opus Interactive Audio Codec)
Opus is currently the most efficient audio codec: it delivers the best possible quality at very low bitrates. It is the format of WhatsApp, Telegram and Discord voice messages and of video calls. Excellent, but still poorly recognized by consumer players and car stereos.
- Exceptional quality at low bitrates
- Free format
- The standard for voice on the internet
- Very few devices play it
- Often impossible to open on Windows without extra software
