WMA ka AMR FAQ Konversi
How do I convert WMA to AMR audio?
+
Upload your WMA file and PDF.to re-encodes it into a AMR container with sensible default bitrate and sample-rate. The AMR download is ready in seconds.
Is WMA to AMR a lossy or lossless conversion?
+
If both WMA and AMR are lossless (WAV, FLAC, AIFF), no quality is lost. If AMR is lossy (MP3, AAC, OGG, Opus), audio is re-encoded; we default to a high bitrate (192-320 kbps) for near-transparent quality.
What bitrate does the AMR output use?
+
192 kbps by default for AMR where applicable. Use the options panel to pick 96, 128, 192, 256, or 320 kbps depending on whether you want smaller files or higher fidelity.
Are tags (artist, title, album) preserved when converting WMA to AMR?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when AMR supports it.
Will sample-rate and bit-depth survive the WMA to AMR conversion?

Does PDF.to support multi-channel (5.1, 7.1) WMA files?
+
Yes for AMR formats that support multi-channel (AC3, FLAC, Opus). For stereo-only targets, multi-channel audio is downmixed using a perceptually weighted mix.
Can I batch-convert WMA files to AMR?
+
Yes. Drop a whole folder of WMA files; each becomes a separate AMR and all are zipped for download.
Is the WMA to AMR converter free?
+
Yes, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
Does the converter remove DRM from WMA files?
+
No. PDF.to teu ngacobaan ngaleupaskeun DRM. Konversi ngan bisa réngsé dina berkas sumber anu teu dilindungi.
Will the AMR I download play on iPhone, Android, and desktop?
+
Yes. AMR is supported natively across all major platforms or via universally available codecs. We default to the most-compatible AMR profile.
Are my WMA files private during conversion?
+
Yes. Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the WMA and AMR files are deleted within an hour.
