Is this MOV to M4A converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple MOV files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

What bitrate will the converted audio use?

We default to 192 kbps for MP3, 128 kbps for OGG/Opus, and 320 kbps for M4A/AAC. These settings are perceptually transparent — most listeners can't tell the difference in a blind test.

Will my metadata (ID3 tags, album art) be preserved?

Yes, when both formats support it. Tags carry over on conversions like MP3→M4A or FLAC→MP3. WAV has limited tag support, so some metadata may not transfer.

Is MOV to M4A conversion just a container change?

Usually yes — both MOV and M4A are container formats, and MOV from Apple devices typically contains AAC audio. The converter remuxes the audio track without re-encoding, making it instant and lossless.

I recorded a voice memo on Mac as MOV — can I convert it to M4A for my iPhone?

Yes — QuickTime recordings on Mac save as MOV. Converting to M4A makes them immediately compatible with iPhone's Music app and Voice Memos import.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert MOV to M4A?

QuickTime recordings from Mac, screen recordings from iPhone, and video exports from iMovie all save as MOV by default. If the recording captured something you want in your music library — a live performance, a podcast interview, an audio book chapter — you need to strip the video and keep just the audio in a format Apple's ecosystem recognizes as audio: M4A.

M4A is structurally the same as MOV and MP4, just restricted to the audio track and recognized by every Apple product as an audio file rather than a video file. Converting MOV to M4A remuxes the AAC audio stream directly — no re-encoding, no quality loss, and the operation completes in seconds regardless of file size. iTunes, Apple Music, GarageBand, Logic Pro, and iOS all accept M4A natively; drag it in and it's ready to sync or play.

The resulting M4A is far smaller than the MOV source because it contains only the audio data. A 30-minute MOV screen recording might be 800 MB; the M4A audio will be around 60 MB at 256 kbps AAC. For voice memos and podcast drafts captured as MOV video, this is the simplest path to a distributable audio file.

Quality & file size: MOV to M4A

Typical file sizes: MOV 150–500 MB → M4A 3–6 MB.

Both MOV and M4A use lossy compression. We transcode at high quality settings (equivalent to M4A's recommended web quality) to minimize generational loss.

Color depth: MOV supports standard color, M4A supports standard color.

Transparency: MOV does not support transparency. M4A does not support transparency — transparent areas become solid white.
