AIFF to TTA Converter
FileFlip converts AIFF to TTA entirely inside your browser, using FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an AIFF file to TTA?#
- Drop your AIFF file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to TTA and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the TTA file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting AIFF to TTA lose quality?#
No. Converting AIFF to TTA writes the data out again without discarding any of it, so nothing that was in the AIFF file is lost on the way. What changes is the size of the file, not what is inside it.
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 AIFF to TTA actually does to the file#
Converting AIFF to TTA runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, writes the data out again without discarding any of it, and drops encoded streams.

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.
What is a TTA file?#
A TTA file holds audio compressed with True Audio, a lossless codec built by Aleksander Djuric around real-time hardware encoding, so it decodes with very little CPU overhead compared to other lossless formats.
There is little reason to choose TTA over FLAC for a new lossless rip today; it mainly persists in existing archives and on older hardware players that already support it.
Convert TTA to FLAC for playback on current phones, players, and software, since FLAC covers the same lossless ground with far wider support.
AIFF to TTA 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.
