Convert MOV files to M4A free in your browser — no signup, no install, and the file is never uploaded to a server. M4A opens almost anywhere, so the result works where MOV did not.
Add your MOV file
Drag the MOV file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm M4A as the output
M4A is already selected as the output format on this page. You can pick the bitrate — higher keeps more of the sound, lower makes a smaller file.
Run the conversion
Press the convert button. Video is re-encoded frame by frame on your own machine, so a long clip can take several minutes. The tab has to stay open.
Download the M4A file
When it finishes, download the M4A file. Converting multiple files gives you the option to download them together as a ZIP.
Apple's video container and the default for footage shot or edited on iPhone and Mac. It is edit-friendly but tends to produce large files.
An audio file in an MPEG-4 container, usually compressed with AAC. iPhone voice memos and iTunes purchases use this format.
Yes. MOV to M4A conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the MOV file never leaves your device. That is also why it works without an internet connection once the page has loaded.
M4A uses lossy compression, so some detail is discarded. At high quality settings the difference is usually invisible, and the file becomes far smaller.
Yes — M4A is an audio format, so only the soundtrack is extracted. The video track is dropped, which is usually the point when you want just the audio.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
