AIFF Converter
FileFlip converts AIFF files into 11 other formats entirely inside your browser, using WebCodecs and FFmpeg compiled to WebAssembly. The AIFF file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert an AIFF file?#
- Drop your AIFF file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert AIFF files online?#
Yes, because nothing is uploaded. FileFlip converts AIFF files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is an AIFF file?#
An AIFF file stores uncompressed PCM audio samples in Apple's Audio Interchange File Format, a structure the company built on Electronic Arts' IFF in 1988 for professional and Mac-native audio.
Use AIFF for recording and editing on macOS, where it's the native uncompressed format for tools like Logic Pro and GarageBand.
Convert AIFF to WAV for compatibility with non-Apple software, or to FLAC or MP3 once editing is done and the file needs to be smaller for distribution.
The AIFF file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
AIFF questions people ask#
Is AIFF a lossless format?
Yes, AIFF is lossless: it stores raw, uncompressed PCM audio samples with nothing removed or approximated, so what you hear back is identical to what was recorded. Unlike FLAC, standard AIFF doesn't compress the audio at all, so there's no encode-decode step where anything could go wrong.
What's the difference between AIFF and WAV?
AIFF and WAV both store uncompressed PCM audio and are equivalent in quality; the difference is mostly heritage and byte order. AIFF, developed by Apple, stores samples big-endian and is the default on macOS audio tools, while WAV, developed by Microsoft and IBM, stores samples little-endian and is the default on Windows.
Does converting AIFF to MP3 lose quality?
Yes, converting AIFF to MP3 loses quality, because MP3 is a lossy codec that permanently discards audio data during compression, while AIFF is uncompressed. The loss is usually inaudible at a high bit rate like 256-320 kbps, but it is real and can't be undone by converting back to AIFF.
What plays AIFF files?
Apple's Music and QuickTime Player play AIFF natively, as do Logic Pro, GarageBand, Audacity and most professional DAWs on any platform. VLC also plays AIFF on Windows and Linux, though consumer media players and streaming services outside Apple's ecosystem often don't support it at all.
Why does GarageBand or Logic export AIFF instead of MP3?
Logic Pro and GarageBand default to AIFF for exports because it's Apple's native uncompressed format and keeps every bit of the recorded or mixed audio intact, with no lossy compression applied. MP3 is a better choice once the mix is final and the file needs to be small enough to share or stream.
