Convert AIFF to OGG
Turn your AIFF into an OGG. AIFF is uncompressed audio on a Mac, the Apple counterpart to WAV. The practical difference is that the result opens anywhere, which AIFF files do not. Your file never leaves your computer.

How to convert AIFF to OGG
- 1 Drop your AIFF .aiff or .aif or .aifc file onto the page, or click to browse for it.
- 2 Set the quality, or leave the default, which keeps the file small without anything showing.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the OGG, or add more files and do the whole set in one go.
Why convert AIFF to OGG
- An AIFF will not open in a browser, so anything going onto a web page, into a document or into a message has to become an OGG first.
- OGG files come out much smaller, which is the difference between a page that loads straight away and one that keeps people waiting.
- Patent free and open, with no licensing to worry about.
- Better quality than MP3 at the same file size.
- Web audio where Safari is not the only target.
AIFF compared with OGG
How the two formats differ on the things that decide whether a conversion is worth making.

| Compression | Uncompressed | Lossy |
| Typical file size | Largest | Smaller |
| Browser support | Some browsers | All current browsers |

Quality and what changes
This is the step where information is discarded, and it cannot be undone by converting back later. OGG throws away detail the eye is least likely to notice, which is invisible at sensible settings and shows as blocking around sharp edges and text when pushed hard. Keep the AIFF as your master and treat the OGG as a delivery copy.
- One OGG limitation to keep in mind: apple devices and many car stereos will not play it.
Questions about AIFF to OGG
Is my AIFF file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your AIFF is read straight from your own disk, converted on your machine and handed back as an OGG. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several AIFF files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate OGG downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
