Why convert MOV to AAC?

Your iPhone or Mac records video as MOV, and that MOV contains an AAC audio track — the same high-quality codec used by iTunes, Apple Music, and every streaming platform. But if all you need is the audio (for a podcast, a voice note upload, a background music clip), carrying the video track around is wasteful. MOV files are accepted by few upload forms and are rejected by most podcast platforms entirely.

Extracting the AAC from a MOV is a direct container-level operation. The AAC audio stream already inside the MOV is copied into a standalone AAC file without any re-encoding — which means the operation is fast and the audio quality is exactly identical to what was inside the video. No generation loss, no additional compression. Apple devices, Android phones, Spotify, SoundCloud, and every streaming platform that accepts audio will play or accept AAC without issues.

The output file will be a fraction of the MOV's size — typically 5–15× smaller, since the video track (which holds the bulk of the data) is discarded. The AAC file can be renamed to .m4a if your destination app prefers that extension; both are the same format.

Quality & file size: MOV to AAC

Typical sizes: MOV 150–500 MB (1 minute 1080p); AAC 2–5 MB (3-minute song).

AAC output is encoded at 192 kbps.

Re-encoding one lossy format into another adds a second round of compression.

Frequently asked questions

Does extracting AAC from MOV reduce quality?
Not for iPhone videos. Their sound is AAC, so it is copied straight out, not re-encoded, and the quality is bit-for-bit identical. Other sound, such as the PCM some cameras record, is encoded to AAC at 192 kbps.
Can I use the AAC from a MOV in a podcast or YouTube upload?
Yes — extracted AAC is immediately usable for podcast uploads (most hosts accept AAC/M4A) and video platforms. Rename to .m4a if your tool prefers that extension.
