OGG to OGA Converter

What happens when you convert OGG to OGA

• OGG and OGA are the same format with different extensions, so nothing is re-encoded. The file is copied byte for byte and saved with a .oga extension.
• Because the bytes are identical, the OGA has exactly the same quality, dimensions and size as the OGG.

How to convert OGG to OGA online

1. Press "Choose OGG 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 OGA". The first audio or video conversion downloads the converter engine, about 32 MB, which your browser then keeps for next time.
4. Save each OGA with its download button. Close the tab and every trace of the files is gone from memory.

Why convert OGG to OGA?

OGG files usually come from video games, desktop streaming apps and open-source software. People convert them to OGA because OGA is the Ogg audio extension some Linux players, games and web apps ask for.

In short, OGG is good at what it was made for, and OGA is the more practical choice when the file has to play on another device or app. OGG plays in Chrome, Firefox and Edge; Safari support is recent and incomplete, while OGA plays in Chrome, Firefox and Edge; many desktop players do not recognise the extension.

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

On Windows

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

On a Mac

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

On iPhone and iPad

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

On Android

Open the page in Chrome, tap Choose OGG files and pick them from Files or your gallery. The OGA 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.

OGG vs OGA: the differences

About OGG and OGA 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.

What is an OGA file?

The .oga extension was introduced to mark Ogg files that contain only audio. The contents are the same as a typical .ogg, but plenty of software only looks for the older extension.

OGG to OGA 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 OGA can store them, but cover art is not carried over.

Convert OGG to OGA 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 OGA with the same kind of settings:

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

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