How do I convert OGG to AIFF?

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

No. AIFF is a lossless format, so the conversion preserves exactly what is in your OGG file. Note that it cannot recover detail that was already discarded when the OGG was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 300 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.

OGG and AIFF explained

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

AIFF is Apple's uncompressed audio format, functionally equivalent to WAV but with better metadata support and big-endian byte order.

Where OGG files come from: Game audio, Spotify's older streams and open-source projects.
Where AIFF is used: Mac audio production and older Apple software.

OGG vs AIFF

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

OGG compared with AIFF
Property	Source	Target
Compression	Lossy	Uncompressed
Introduced	2000	1988
Browser support	Browsers and Android. Not native on Apple.	Strong on Apple, decent elsewhere.

OGG is stronger at: Royalty-free. Good quality per bit. Well supported in game engines and browsers.
AIFF is stronger at: Uncompressed and lossless. Better metadata handling than WAV. Standard in Mac audio workflows.

Why convert OGG to AIFF?

People make this switch when they run into the limits of OGG: sharing with iPhone users or general distribution. AIFF is the better fit when audio production on a Mac.

Be aware of the size trade-off: AIFF is uncompressed, so expect the converted file to be considerably larger than the OGG you started with.

OGG limitations that prompt the switch: Apple devices do not support it natively. Largely superseded by Opus. Poor support in consumer hardware.
What you give up: Very large files. Less universally supported than WAV.

Does converting OGG to AIFF reduce quality?

Going from OGG to AIFF moves already-compressed data into a format that stores it exactly. Nothing is lost from this point on, but nothing is recovered either — the detail OGG discarded when the file was first created is gone permanently. Expect a noticeably larger file for identical visual quality.
