Frequently Asked Questions
Why convert MP3 to AIFF?
MP3 (MPEG-1 Audio Layer 3) uses lossy compressed encoding and is best for universal music playback and sharing across all devices and platforms. AIFF (Audio Interchange File Format) uses uncompressed lossless encoding and excels at Apple professional audio — Logic Pro, GarageBand, and macOS music production workflows. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
When using MP3 to AIFF, will the audio quality improve?
No. Converting from lossy MP3 to lossless AIFF does not restore lost data. The AIFF file will be larger but fidelity is limited by the MP3 source.
How large will the AIFF file be?
AIFF is uncompressed, so expect 5-10x the MP3 file size. A 5MB MP3 may become 30-50MB as AIFF.
What sample rates are preserved?
The converter preserves the original sample rate. Common MP3 rates: 44.1kHz, 48kHz. The AIFF output matches the source properties.
Is MP3 to AIFF conversion done locally?
Yes. All conversion runs in your browser using FFmpeg WASM. No audio files are uploaded.
