WMA to Opus Conversion FAQ
How do I convert WMA to Opus audio?
+
Upload your WMA file and PDF.to re-encodes it into a Opus container with sensible default bitrate and sample-rate. The Opus download is ready in seconds.
Is WMA to Opus a lossy or lossless conversion?
+
If both WMA and Opus are lossless (WAV, FLAC, AIFF), no quality is lost. If Opus 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 Opus output use?
+
192 kbps by default for Opus 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 Opus?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when Opus supports it.
Will sample-rate and bit-depth survive the WMA to Opus conversion?
+
Yes by default. We do not downsample or dither unless you ask for it in the options panel. For voice you can opt into 22 kHz mono to shrink file size.
Can I convert a stereo WMA to mono Opus?
+
Yes — toggle the 'force mono' option. This is useful for podcasts and voice memos to roughly halve file size.
Does PDF.to support multi-channel (5.1, 7.1) WMA files?
+
Yes for Opus 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 Opus?
+
Yes. Drop a whole folder of WMA files; each becomes a separate Opus and all are zipped for download.
Is the WMA to Opus converter free?
+
Yes for files under 100 MB. PRO unlocks larger files (5 GB), parallel jobs, and higher bitrates.
Does the converter remove DRM from WMA files?
+
No. PDF.to does not attempt to remove DRM. Conversions only succeed on unprotected source files.
Will the Opus I download play on iPhone, Android, and desktop?
+
Yes. Opus is supported natively across all major platforms or via universally available codecs. We default to the most-compatible Opus 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 Opus files are deleted within an hour.
