AIFF Transformation FAQ
What is a AIFF audio file?
+
AIFF is a lossless audio format — every sample is preserved bit-perfectly. AIFF is ideal for archival masters, audio editing, and any workflow that may re-encode the audio multiple times without accumulating compression artifacts. AIFF is a first-class Apple audio format and is the default for many iOS apps including Voice Memos and the Music app.
Is AIFF lossy or lossless?
+
AIFF is lossless — the audio you encode is the audio you get back.
What should I convert AIFF to for sharing?
+
For email and social-media sharing, convert AIFF to MP3 — universal playback and small file size. For high-fidelity sharing with audiophiles, convert to FLAC or WAV to preserve the original quality.
How much will conversion change the file size?
+
Converting AIFF to a lossless format like WAV or FLAC keeps the size large; converting to MP3 or AAC at common bitrates (192-320 kbps) shrinks the file by roughly 5-10x with minimal perceptible quality change.
Will my AIFF ringtone work on iPhone?
+
iPhone ringtones need to be in M4R format (Apple's ringtone container). Convert AIFF to M4R using MOV.to, then transfer the M4R file to your device through Finder or Apple Devices.
How long can a AIFF file be before MOV.to refuses it?
+
There is no hard time limit — the cap is on file size. Free users get 100 MB per upload (often an hour or more of AIFF audio at common bitrates). Pro users go up to multiple GB.
Does MOV.to preserve metadata (tags, album art) from AIFF?
+
Yes — ID3 tags, artist/album/title, and embedded artwork in your AIFF file are preserved in the output where the destination format supports them. WAV strips most metadata by design, so converting to WAV will drop tags.
Can I extract audio from a video as AIFF?
+
Yes. Upload an MP4, MOV, MKV or any supported video and pick AIFF as the output. MOV.to demuxes the audio track and re-encodes only if needed.
Does MOV.to delete my AIFF files after conversion?
+
Yes. Your AIFF upload and the converted output are deleted automatically after a short window. We do not retain, listen to, or share your audio.
What bitrate should I pick when converting from AIFF?
+
For music, 256-320 kbps is the sweet spot — transparent to most listeners. For voice and podcasts, 96-128 kbps is plenty. Going higher than the source bitrate cannot recover quality the source already lost.
