AIFF to MOV Conversion FAQ
What does the AIFF to MOV converter do?
+
It converts a AIFF file into MOV format.
Will the data inside my AIFF be preserved when converting to MOV?
+
Yes — the content is mapped to the MOV equivalent. Format-specific extras that MOV does not represent natively are omitted rather than corrupted.
Is the AIFF to MOV conversion reversible?
+
You can convert the MOV back to AIFF on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
How much smaller will the MOV be than my AIFF?
+
Typically 5-10x smaller for images, 5-15x smaller for audio. Exact ratio depends on the chosen quality level and the content — flat solid-colour images and silent audio compress far more than detailed photos or busy soundtracks.
What will the picture be if I put AIFF audio into an MOV file?
+
You choose it, because audio alone has no picture. The default is a static waveform render, and you can supply a still image instead — cover art, a title card, a photo — which is held for the whole duration. That is what makes the file uploadable to video-only platforms that will not accept a bare audio track. AIFF is Apple’s Audio Interchange File Format from 1988, built on the same IFF chunk design as AVI’s RIFF. MOV is the format professional editors ask for, because it survives repeated round-trips through Final Cut Pro, Premiere and DaVinci Resolve without generational loss.
Is the AIFF audio re-encoded when it goes into the MOV?
+
Only if it has to be. Where the MOV container accepts the source audio codec directly, the stream is copied in untouched and stays bit-identical. Where it does not, the audio is transcoded once to whatever MOV does accept, at a bitrate matched to the source so the second pass costs as little as possible. AIFF stores uncompressed big-endian PCM — the Apple-side equivalent of WAV, with the same bit-for-bit fidelity. An MOV normally carries H.264 or HEVC for delivery, or ProRes when it is an editing master, alongside AAC or uncompressed PCM audio.
My AIFF is lossless — does putting it in an MOV throw that away?
+
It usually does, because video containers expect a compressed audio track and most players will not accept raw PCM inside one. The audio is encoded once, at a high bitrate so the loss is inaudible, and the lossless AIFF stays untouched on your side. Keep it: it remains the master, and the MOV is a delivery copy. AIFF is the studio interchange format on macOS, handles metadata better than plain WAV, and imports into Logic and Pro Tools instantly.
How large will the MOV be compared with the AIFF?
+
Barely larger, if you use the default still image. A single held frame compresses to almost nothing across the whole duration because every frame is identical to the last, so the file is dominated by the audio track. Choosing an animated waveform instead adds real video data and can double or triple the result.
Do the artist and album tags on my AIFF survive into the MOV?
+
Partially. Title and artist map onto the video container’s own metadata fields, and embedded cover art is a natural fit for the still image the video displays. Everything else — track number, album, year, genre — has no equivalent slot in a video file and is dropped rather than approximated.
Will a surround mix in the AIFF stay surround inside the MOV?
+
Yes — MOV carries multichannel audio properly, so a 5.1 mix stays 5.1 with the channel layout intact rather than being folded to stereo. That matters if the file is destined for a home cinema receiver rather than a phone, which will downmix at playback time anyway.
Is there a file-size limit when converting AIFF to MOV?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several AIFF files to MOV at once?
+
Yes. Drop or pick multiple AIFF files in one upload — the converter processes them in parallel and returns a ZIP of the MOV results. There is no need to repeat the upload step per file.
