AIFF → MP3
Convert AIFF to MP3 – locally in your browser
Why AIFF → MP3?
AIFF files are uncompressed and therefore often tens of megabytes large. Converting to MP3 reduces file size by up to 90% with sufficient quality for most purposes – ideal for mobile playback and sharing.
Frequently Asked Questions
What is an AIFF file?
AIFF (Audio Interchange File Format) is an uncompressed audio format from Apple. It offers studio quality but creates very large files.
Are my files safe?
Yes, 100%. The conversion happens completely locally in your browser – your files are never uploaded to a server.
Can I convert multiple files at once?
Yes, you can upload and convert as many AIFF files as you want at the same time.
Is the conversion free?
Yes, wandlio.de is completely free. No registration, no limits, no ads.
About MP3
MP3 (MPEG-1 Audio Layer III) was finalized in 1993 as ISO 11172-3 and revolutionized the music industry as the first format to achieve near-CD quality at compression ratios of approximately 10:1. The algorithm uses psychoacoustic models that remove frequencies inaudible to the human ear and typically achieves bitrates of 128 to 320 kbps. Development began in 1987 at the Fraunhofer Institute under Karlheinz Brandenburg, who is considered the father of MP3. The format enabled the rise of Napster, the iPod, and the entire digital music distribution ecosystem. MP3 supports ID3 tags for metadata such as artist, album, and cover art, variable bitrates, and streaming. The essential patents expired in 2017, making MP3 royalty-free. While AAC and Opus deliver better quality at the same bitrate, MP3 remains the format with the highest compatibility - every playback device, browser, and software from the last 25 years supports it.
About AIFF
AIFF (Audio Interchange File Format) was introduced in 1988 by Apple in collaboration with Electronic Arts as the standard format for uncompressed audio on Macintosh systems. Analogous to WAV on Windows, AIFF stores audio data as raw PCM samples in the IFF container and supports sample rates up to 384 kHz, bit depths up to 32 bits, and multiple channels. AIFF is the reference format in professional music production on macOS, particularly in Apple Logic Pro and studio environments requiring maximum quality without compression. File sizes are equivalent to WAV - one minute of stereo CD quality takes up approximately 10 MB. A compressed variant, AIFF-C, is rarely used. Since macOS Big Sur, Apple also supports FLAC, which is increasingly displacing AIFF as an uncompressed format. For archiving, FLAC is preferable; for broad compatibility, WAV or MP3.
Why convert AIFF → MP3?
AIFF (Audio Interchange File Format) is Apple's uncompressed audio format — functionally equivalent to WAV but with Mac-specific metadata. A 3-minute AIFF track is typically 30 MB, making it impractical for all everyday applications. Converting to MP3 is needed to massively reduce file size (MP3: 90% smaller, FLAC: 50% smaller) or establish compatibility with non-Apple systems. MP3 makes AIFF files usable on Windows, Android, streaming, and email delivery. MP3 is the most universal audio format — playable on every device and player, ideal for mobile use and sharing.
