WMA 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 WMA to another lossy format causes generational quality loss; convert from a lossless master when possible.
Is WMA lossy or lossless?
+
WMA is lossy — the encoder removes data the encoder judges to be inaudible to reach a small file size.
What should I convert WMA to for sharing?
+
For email and social-media sharing, convert WMA 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 WMA 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 WMA ringtone work on iPhone?
+
iPhone ringtones need to be in M4R format (Apple's ringtone container). Convert WMA to M4R using MOV.to, then transfer the M4R file to your device through Finder or Apple Devices.
How long can a WMA 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 WMA audio at common bitrates). Pro users go up to multiple GB.
Does MOV.to preserve metadata (tags, album art) from WMA?
+
Yes — ID3 tags, artist/album/title, and embedded artwork in your WMA 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 WMA?
+
Yes. Upload an MP4, MOV, MKV or any supported video and pick WMA as the output. MOV.to demuxes the audio track and re-encodes only if needed.
Does MOV.to delete my WMA files after conversion?
+
Yes. Your WMA 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 WMA?
+
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.
