WMA to AIFF Conversion FAQ
How do I convert WMA to AIFF audio?
+
Upload your WMA file and PDF.to re-encodes it into a AIFF container with sensible default bitrate and sample-rate. The AIFF download is ready in seconds.
Is WMA to AIFF a lossy or lossless conversion?
+
If both WMA and AIFF are lossless (WAV, FLAC, AIFF), no quality is lost. If AIFF 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 AIFF output use?
+
192 kbps by default for AIFF 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 AIFF?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when AIFF supports it.
Will sample-rate and bit-depth survive the WMA to AIFF 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 AIFF?
+
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 AIFF 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 AIFF?
+
Yes. Drop a whole folder of WMA files; each becomes a separate AIFF and all are zipped for download.
Is the WMA to AIFF 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 AIFF I download play on iPhone, Android, and desktop?
+
Yes. AIFF is supported natively across all major platforms or via universally available codecs. We default to the most-compatible AIFF 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 AIFF files are deleted within an hour.
