About converting MP3 to AIFF
If something is asking you for a AIFF file and all you have is a MP3, this page is the fix. Drop in your MP3 file (a .mp3) and download a ready-to-use AIFF file (a .aiff) — no software to install, no account to create, and no watermark on the output.
What is MP3?
MP3 is the most universally compatible audio format ever made — lossy, small, and playable on absolutely everything. The safe default when you just need audio that works anywhere.
What is AIFF?
AIFF is an audio format. Converting it trades off file size, quality and compatibility to fit where the sound will be played.
Why convert MP3 to AIFF?
You'll reach for a MP3 to AIFF conversion whenever the other end expects AIFF specifically — uploading somewhere, importing into software, or sharing with someone whose device prefers it. Audio is processed with ffmpeg using high-quality encoders (LAME, libopus, libvorbis, FLAC and more), so you get the best possible result for the destination format.
MP3 vs AIFF: what changes
Going from the lossy MP3 to the lossless AIFF won't recover detail MP3 already discarded, but it gives you a clean, re-editable copy that won't degrade further when you edit and re-save it.
When you'd convert MP3 to AIFF
It comes up when publishing online, submitting to a service with strict format rules, or archiving a collection in a single consistent format.
Is it private?
Privacy is the default here. Your MP3 file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
