M4R Mistoqsijiet Frekwenti dwar il-Konverżjoni
What is a M4R audio file?
+
M4R is a lossy audio format. The encoder discards inaudible frequencies and masked sounds to reach file sizes roughly a tenth of an uncompressed equivalent. Re-encoding M4R to another lossy format causes generational quality loss; convert from a lossless master when possible. M4R is a first-class Apple audio format and is the default for many iOS apps including Voice Memos and the Music app.
Is M4R lossy or lossless?
+
M4R is lossy — the encoder removes data the encoder judges to be inaudible to reach a small file size.
What should I convert M4R to for sharing?
+
For email and social-media sharing, convert M4R to MP3 — universal playback and small file size. For high-fidelity sharing with audiophiles, convert to FLAC or WAV to preserve the original quality.
How much will conversion change the file size?
+
Converting M4R to a lossless format like WAV or FLAC keeps the size large; converting to MP3 or AAC at common bitrates (192-320 kbps) shrinks the file by roughly 5-10x with minimal perceptible quality change.
Will my M4R ringtone work on iPhone?
+
iPhone ringtones need to be in M4R format (Apple's ringtone container). Convert M4R to M4R using MOV.to, then transfer the M4R file to your device through Finder or Apple Devices.
How long can a M4R file be before MOV.to refuses it?
+
There is no hard time limit — the cap is on file size. Free users get 100 MB per upload (often an hour or more of M4R audio at common bitrates). Pro users go up to multiple GB.
Does MOV.to preserve metadata (tags, album art) from M4R?
+
Yes — ID3 tags, artist/album/title, and embedded artwork in your M4R file are preserved in the output where the destination format supports them. WAV strips most metadata by design, so converting to WAV will drop tags.
Can I extract audio from a video as M4R?
+
Yes. Upload an MP4, MOV, MKV or any supported video and pick M4R as the output. MOV.to demuxes the audio track and re-encodes only if needed.
Does MOV.to delete my M4R files after conversion?
+
Yes. Your M4R upload and the converted output are deleted automatically after a short window. We do not retain, listen to, or share your audio.
What bitrate should I pick when converting from M4R?
+
For music, 256-320 kbps is the sweet spot — transparent to most listeners. For voice and podcasts, 96-128 kbps is plenty. Going higher than the source bitrate cannot recover quality the source already lost.
