Compress MOV to M4A

Need smaller audio files? Converting MOV to M4A dramatically reduces file size. A 50MB file becomes 5MB. Perfect for email, sharing, and storage.

MOV (.mov) · Max 20 MB

MOV files are already compressed, but M4A can compress further at a different bitrate. The size reduction is significant for sharing, uploading, and storage.

For email attachments, 128-192kbps works well. For music sharing, use 256-320kbps. AudioUtils lets you drop your file and convert instantly. No upload to a server, no waiting.

MOV costs you around 60 MB for every minute; M4A asks for about 1.2. Over a long recording that gap is the whole reason to convert. Two lossy formats in a row means two rounds of the encoder guessing what you won't miss. At a high bitrate the second guess is harmless; at a low one it compounds.

The MOV on your drive almost certainly started life in iPhone videos, and MOV is Apple's QuickTime container, and the video track is almost the whole file when all you wanted was the sound. M4A is the destination because it plays essentially everywhere — iPhone Voice Memos and every ordinary phone, browser, and player. A minute of MOV is about 60 MB; the same minute as M4A is roughly 1.2. Across an album or a long recording that difference decides whether it fits on a phone. Both MOV and M4A are lossy, so this pair stacks a second encode — at a generous bitrate it stays inaudible, but if a lossless original of the MOV exists, encode the M4A from that instead.

Frequently Asked Questions

How much smaller will the file get?

MOV costs you around 60 MB for every minute; M4A asks for about 1.2. Over a long recording that gap is the whole reason to convert.

What bitrate keeps the quality acceptable?

192–256 kbps is transparent for most music, 128 kbps is fine for speech, and 64–96 kbps mono is plenty for pure voice — halving the size again with no real cost. Below that you start hearing it.

Will compressing damage the audio?

Two lossy formats in a row means two rounds of the encoder guessing what you won't miss. At a high bitrate the second guess is harmless; at a low one it compounds.

Should I compress a master or an archive copy?

Never the master. Compress a copy for sharing and listening, and keep the original — you can always re-encode from it, but you can never re-create what a lossy encoder discarded.

Is this compressor free?

Yes. Free users get 5 conversions per month. The output is limited to the first 10 seconds as a preview, with a 20MB input file size limit. Upgrade to Pro for unlimited, full-length conversions.
