How to convert AIFF to MP3

  1. Add your AIFF audio files

    Drop AIFF (AIF) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. MP3 is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

    Save the MP3, or download everything as one ZIP if you converted several files.

AIFF to MP3: what to expect

AIFF files are very large and are not played by many phones or websites. MP3 plays on every phone, computer, car stereo and speaker. AIFF is at home in audio production on the Mac; MP3 is the usual choice for music and podcasts that must play anywhere. MP3 is lossy, so keep the AIFF original if you may need full quality later.

The defaults suit most files. Under Options you can choose the bitrate and trim the start and end.

This pair uses the compatibility engine, ffmpeg built for the browser, because AIFF is not handled by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB. MP3 is written at 192 kbps unless you choose another bitrate.

AIFF vs MP3

AIFF

AIFF audio

AIFF is Apple's counterpart to WAV: uncompressed audio with full quality and large files. Logic and GarageBand use it heavily.

Opens in macOS, audio editors, most DAWs; browsers and phones vary

MP3

MP3 audio

MP3 is the audio format everything plays. It shrinks audio to roughly a tenth of its uncompressed size by discarding sound most listeners cannot hear. Newer codecs are more efficient, but nothing matches its compatibility.

Questions

Are my audio files uploaded anywhere?

No. The AIFF to MP3 conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting AIFF to MP3 reduce quality?

MP3 is a lossy format, so a small amount of detail is traded for a smaller file. At the default setting the difference is hard to notice. You can choose the bitrate under Options.

Can I convert several AIFF files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert AIFF to MP3 on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the AIFF file, press Convert and save the MP3. There is nothing to install.

Is there a file size limit?

Yes. AIFF to MP3 runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
