AIFF (.aiff) · Max 20 MB
Gmail, Outlook, and Yahoo all cap attachments at 25MB. A single AIFF file often exceeds that within minutes of audio. Converting to MP3 at 128kbps keeps file sizes well under the limit.
For voice recordings and meetings, 128kbps mono is plenty. For music, 192kbps stereo sounds great and stays small. AudioUtils converts in your browser — no upload needed, no file touching anyone's server.
Drop your file, convert, download, attach. The whole process takes seconds. No signup, no email address required, no watermarks.
Frequently Asked Questions
What is AIFF?
Audio Interchange File Format. Apple's version of WAV. It stores uncompressed audio with support for metadata and album art. Common in Mac audio production.
How much smaller will the MP3 be?
About 80% smaller. A 40MB AIFF file becomes roughly 7-8MB as a 320kbps MP3.
Should I use AIFF or WAV for production?
Either works. AIFF has slightly better metadata support on Mac. WAV is more universal. Both are uncompressed with identical audio quality.
Is AIFF the same as Apple Lossless (ALAC)?
No. AIFF is uncompressed (like WAV). ALAC is lossless compressed (like FLAC). ALAC files are smaller but both preserve full quality.
