How do I convert OGV to AAC?

Add your OGV file to the upload area above, then press Convert. The AAC 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 AAC reduce quality?

AAC 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.

OGV and AAC explained

OGV is the Ogg container carrying Theora video, an early royalty-free codec that has been comprehensively superseded by VP9 and AV1.

AAC is the successor to MP3 and is the default audio codec for MP4 video, Apple Music and YouTube. At the same bitrate it generally sounds noticeably better than MP3.

Where OGV files come from: Open-source projects and Wikipedia media from the early 2010s.
Where AAC is used: Streaming services, video soundtracks and Apple devices.

OGV vs AAC

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

OGV compared with AAC
Property	Source	Target
Compression	Container (depends on codec)	Lossy
Animation	Yes	—
Introduced	2008	1997
Browser support	Firefox and Chrome. Largely superseded by WebM.	Excellent across modern devices.

OGV is stronger at: Royalty-free. Open specification.
AAC is stronger at: Better quality per bit than MP3. The standard audio track for MP4 video. Excellent device support.

Why convert OGV to AAC?

This is not really a format swap — it is extraction. An OGV file carries a video track and an audio track side by side, and converting to AAC 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.

OGV limitations that prompt the switch: Theora compresses poorly compared with anything modern. Very limited support. No reason to choose it today.
What you give up: Still lossy. Patent licensing applies to encoders.

Does converting OGV to AAC reduce quality?

OGV stores your data exactly; AAC 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 OGV original if it is the only copy — the conversion cannot be undone.
