About converting AIFF to MP3
If something is asking you for a MP3 file and all you have is a AIFF, this page is the fix. Drop in your AIFF file (a .aiff) and download a ready-to-use MP3 file (a .mp3) — no software to install, no account to create, and no watermark on the output.
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.
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.
Why convert AIFF to MP3?
The usual reason to convert AIFF to MP3 is file size or quality: MP3 fits the job better, whether that means a smaller download, a cleaner edit, or broader support. 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.
AIFF vs MP3: what changes
MP3 is lossy, so expect a much smaller file than AIFF — usually at a cost in fidelity small enough to be invisible at normal viewing sizes.
When you'd convert AIFF to MP3
Typical uses: preparing assets for a website, attaching a file someone else can definitely open, or standardising a folder of mixed files into one format.
Is it private?
Privacy is the default here. Your AIFF 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.
