Yes. Uploaded MP4 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted M4R are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Mengapa file M4R saya memiliki celah diam?

Usually the MP4 carries more than one audio track and the one that was converted is silent or secondary. The converter picks one audio track automatically, normally the main one, and this page has no setting to choose a different track. If the wrong one comes out, remux the MP4 with the track you want first (VLC or ffmpeg can do this) and convert it again.

MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. OGG and Opus need a recent player on iOS but play in Chrome, Firefox and VLC. There are no device presets on this page, so choose the target format your player supports.
