How do I convert AVI to OGG?

Add your AVI file to the upload area above, then press Convert. The OGG file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to OGG reduce quality?

OGG uses lossy compression, so some data is discarded. At the default quality the difference is very hard to see or hear; raise the quality setting if you need to be certain, at the cost of a larger file.

How large a file can I convert?

Up to 512 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

AVI and OGG explained

AVI is a Microsoft container from 1992. It predates modern video compression and lacks features taken for granted today, such as proper support for variable frame rates and modern codec metadata.

OGG here means Ogg Vorbis, a royalty-free lossy codec that predates Opus. It is competitive with AAC and remains common in games.

Where AVI files come from: Old camcorders, legacy Windows software and archived downloads.
Where OGG is used: Game audio, Spotify's older streams and open-source projects.

AVI vs OGG

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

AVI compared with OGG
Property	Source	Target
Compression	Container (depends on codec)	Lossy
Animation	Yes	—
Introduced	1992	2000
Browser support	Wide but dated. Not supported in browsers.	Browsers and Android. Not native on Apple.

AVI is stronger at: Readable by very old software. Simple, well understood structure.
OGG is stronger at: Royalty-free. Good quality per bit. Well supported in game engines and browsers.

Why convert AVI to OGG?

This is not really a format swap — it is extraction. An AVI file carries a video track and an audio track side by side, and converting to OGG discards the picture and keeps the sound. People do it to turn a lecture, interview, podcast recording or music video into something they can listen to without the video, at a fraction of the file size.

AVI limitations that prompt the switch: Inefficient — much larger than MP4 for the same quality. No browser support. Poor handling of modern codecs and variable frame rate.
What you give up: Apple devices do not support it natively. Largely superseded by Opus.

Does converting AVI to OGG reduce quality?

AVI stores your data exactly; OGG does not. Some detail is discarded permanently in exchange for a much smaller file, which is usually the right trade for sharing and publishing. Keep your AVI original if it is the only copy — the conversion cannot be undone.
