What is an MP4 file?
MP4 – MP4 video. MP4 is the video format that plays everywhere: phones, browsers, TVs and social networks. It usually holds H.264 pictures and AAC sound. Converting makes a new file: the video is decoded and encoded again, so converting from a format that lost detail never brings it back.
MP4 Converter →What is an AIFF file?
AIFF – AIFF audio. AIFF is Apple's uncompressed audio format, the Mac counterpart of WAV: every sample is kept. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

Frequently asked questions
Is converting MP4 to AIFF free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my MP4 files uploaded anywhere?
This conversion runs on our server, because converting video needs ffmpeg, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the MP4 file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the AIFF look the same as the MP4?
Only the sound is kept: the pictures are left out, and the AIFF is made from the first sound track.
Can I convert several MP4 files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
