AMR to WMA Conversion FAQ
Is AMR to WMA a lossy or lossless conversion?
+
If both AMR and WMA are lossless (WAV, FLAC, AIFF), no quality is lost. If WMA is lossy (MP3, AAC, OGG, Opus), audio is re-encoded; we default to a high bitrate (192-320 kbps) for near-transparent quality.
Can I convert a stereo AMR to mono WMA?
+
Yes — toggle the 'force mono' option. This is useful for podcasts and voice memos to roughly halve file size.
Can I batch-convert AMR files to WMA?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Is the AMR to WMA converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
Does the converter remove DRM from AMR files?
+
No. PDF.to does not attempt to remove DRM. Conversions only succeed on unprotected source files.
Are my AMR files private during conversion?
+
Yes. Uploads travel over HTTPS, nobody reads the contents, and nothing is shared. Your uploaded AMR and the resulting WMA are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result.
