Is Video to M4A free? Is there a watermark?

Yes — Video to M4A is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.

Do my files get uploaded to a server?

No. Video to M4A runs entirely in your browser with WebAssembly, so your MP4, MOV, WebM, MKV file never leaves your device and nothing is stored or seen by us.

What can I put in, and what do I get out?

Video to M4A accepts MP4, MOV, WebM, MKV and gives you back a M4A file. Actual codec support depends on what the bundled engine or browser decoder can read.

What quality is the M4A audio?

The default audio stream is re-encoded as 192 kbps AAC. This is lossy, and alternate source tracks are not exposed for selection.

Best for: Extracting AAC audio for Apple-oriented playback, messaging, music libraries, or voice-note workflows that accept M4A.
Input → output: The default audio stream from MP4, MOV, WebM, or MKV becomes 192 kbps AAC inside an M4A container, with video omitted.
Quality tip: Check that the intended source track is the default and compare dialogue or music transients afterward. Test the M4A in its destination app.
Know before running: This is a lossy AAC re-encode rather than a direct stream copy. Alternate tracks are not selectable, and a video with no audio cannot produce output.
Next step: Audio to MP3 when the extracted sound needs wider playback compatibility.
