Common Use Cases
- Converting Apple music production files for sharing
- Shrinking uncompressed AIFF recordings for portable players
- Creating MP3 versions of GarageBand or Logic exports
AIFF (Audio Interchange File Format) is Apple's uncompressed audio format, commonly used in GarageBand, Logic Pro, and professional Mac audio workflows. The files are pristine in quality but massive in size, typically 10 MB per minute of stereo audio at CD quality. MP3 compresses that down to roughly 1 MB per minute with quality that is indistinguishable from the original for most listeners. Converting from AIFF to MP3 is the standard step for sharing, distributing, or archiving audio when full lossless fidelity is not required.
AIFF stores uncompressed PCM audio at full CD quality (1,411 kbps for 16-bit/44.1 kHz stereo), while MP3 uses perceptual compression to deliver near-identical listening quality at 128 to 320 kbps, reducing file sizes by 80 to 90 percent.
Why Convert AIFF to MP3?
Dramatically smaller file sizes
A 50 MB AIFF file compresses to roughly 5 MB as a high-quality MP3. This makes a huge difference when emailing tracks, uploading to websites, syncing to phones, or managing large music libraries on limited storage.
Universal device and platform support
MP3 is the most widely supported audio format in existence. Every phone, car stereo, portable player, streaming platform, and web browser plays MP3 without issues. AIFF support outside Apple devices is inconsistent.
Share music and recordings easily
When you need to send a track to a collaborator, client, or friend, MP3 is the safe choice. File sizes are small enough for email attachments, and the recipient can play it on any device without worrying about format compatibility.
Export from Apple production tools for distribution
GarageBand and Logic Pro default to AIFF exports. Converting to MP3 is the final step before uploading to SoundCloud, Bandcamp, podcast hosts, or any distribution platform that does not accept uncompressed audio.
When to use each
Use AIFF when...
- Editing and mixing in a DAW like Logic or GarageBand
- Archiving masters at full uncompressed quality
- Playing on Apple devices with ample storage
- The audio will be re-processed or re-edited later
- CD burning or professional mastering workflows
Use MP3 when...
- Sharing tracks via email, chat, or file transfer
- Uploading to streaming platforms or podcast hosts
- Syncing a large library to a phone or portable player
- The listener does not need studio-quality fidelity
- Web playback and embedded audio on websites

How to use
- Upload your AIFF file. Drag and drop an .aiff or .aif file onto the upload area, or click to browse. Files up to 500 MB are supported, which covers hours of uncompressed stereo audio.
- Convert to MP3. Click Convert File. Your AIFF audio is encoded to MP3 using high-quality LAME encoding, preserving as much of the original fidelity as the MP3 format allows.
- Download your MP3. Save the converted MP3 and play it on any device, upload it to a platform, or share it with anyone. Uploaded files are automatically deleted from our servers within 1 hour.
Frequently asked questions
- Will I hear a quality difference between AIFF and MP3?
- At high bitrates (256 to 320 kbps), the difference is inaudible for almost all listeners on normal playback equipment. Only trained ears on studio monitors in treated rooms can reliably detect differences, and even then only on specific test material.
- Are metadata tags preserved?
- Basic metadata like title, artist, album, and track number are carried over from the AIFF to the MP3 as ID3 tags where present in the source file.
- Can I convert AIFF-C (compressed AIFF) files?
- Yes. Both standard uncompressed AIFF and AIFF-C (compressed variant) files are supported. The converter detects the encoding automatically.
- What sample rates are supported?
- The converter handles all common sample rates including 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz. Higher sample rates are downsampled to 44.1 kHz in the MP3 output, which is the standard for consumer audio distribution.
- Is AIFF to MP3 conversion free?
- Yes. Anyone can convert for free with no signup required. Anonymous users get a daily conversion allowance, registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
