OPUS to OGG Converter

What happens when you convert OPUS to OGG

• The audio is decoded and written as Vorbis at 192 kbps.
• Going from one lossy format to another adds a small generation loss. Choose a bitrate at least as high as the source to keep it inaudible.

How to convert OPUS to OGG online

1. Press "Choose OPUS files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
2. Adjust the settings if you need to: the bitrate controls quality and size. The defaults suit most people.
3. Press "Convert to OGG". The first audio or video conversion downloads the converter engine, about 32 MB, which your browser then keeps for next time.
4. Save each OGG with its download button. Close the tab and every trace of the files is gone from memory.

Why convert OPUS to OGG?

OPUS files usually come from WhatsApp and Telegram voice notes, Discord and video calls. People convert them to OGG because OGG Vorbis is free to use and is the standard audio format of many games and game engines.

In short, OPUS is good at what it was made for, and OGG is the more practical choice when the file has to play on another device or app. OPUS plays in current browsers; many car stereos and older players cannot, while OGG plays in Chrome, Firefox and Edge; Safari support is recent and incomplete.

How to convert OPUS to OGG on Windows, Mac, iPhone and Android

On Windows

Open this page in Chrome, Edge or Firefox, drag your OPUS files in from File Explorer, and press Convert. Each OGG is saved to your Downloads folder. If you prefer a desktop program, VLC can also convert OPUS to OGG: choose Media, then Convert / Save.

On a Mac

Safari, Chrome and Firefox all work. Drag the OPUS files from Finder onto the drop zone and the OGG files land in Downloads.

On iPhone and iPad

Open the page in Safari and tap Choose OPUS files. You can pick from Photos or from the Files app. The converted OGG appears in Files, in the Downloads folder.

On Android

Open the page in Chrome, tap Choose OPUS files and pick them from Files or your gallery. The OGG is saved to the Download folder, where any file manager can find it. Keep the screen on while a long video converts, because Android may pause a tab in the background.

Best settings for OPUS to OGG

OGG is a lossy format, so the bitrate decides both the sound quality and the file size. Size grows in a straight line with bitrate: double the bitrate and the file doubles.

The OPUS was already compressed, so pick a bitrate at least as high as the original. Going higher does not add quality back, it only makes the file bigger.

OPUS vs OGG: the differences

About OPUS and OGG files

What is an OPUS file?

Opus was built for speech and music over the internet, and it holds up at bitrates as low as 16 kbps. Voice messages from WhatsApp and Telegram usually arrive as Opus files.

What is an OGG file?

OGG is a free, patent-unencumbered container, and most .ogg files hold Vorbis audio. Game engines use it heavily because it costs nothing to license.

OPUS to OGG not working? Common problems

• The conversion is slow. Audio and container changes take seconds, but re-encoding video runs on your own processor. Lower the resolution to 720p, close other tabs, and keep the device plugged in.
• The tab stops or reloads on a very large file. Browsers limit how much memory one tab can use, around 2 GB and less on phones. Split long recordings or convert them on a computer.
• Song titles are missing. Tags such as title and artist are copied when OGG can store them, but cover art is not carried over.

Convert OPUS to OGG with ffmpeg

This converter runs ffmpeg inside your browser. If you would rather use the ffmpeg command line on your own computer, this command produces an equivalent OGG with the same kind of settings:

ffmpeg -i input.opus -vn -c:a libvorbis -b:a 192k output.ogg

Replace input.opus with the name of your file. For a whole folder of OPUS files, run the command in a loop, or drop them all on the converter above, which processes them one after another.
