Upload your WMA file and PDF.to re-encodes it into a AC3 container with sensible default bitrate and sample-rate. The AC3 download is ready in seconds.
Is WMA to AC3 a lossy or lossless conversion?
+
If both WMA and AC3 are lossless (WAV, FLAC, AIFF), no quality is lost. If AC3 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 AC3 output use?
+
192 kbps by default for AC3 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 AC3?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when AC3 supports it.
Will sample-rate and bit-depth survive the WMA to AC3 conversion?
Does PDF.to support multi-channel (5.1, 7.1) WMA files?
+
Yes for AC3 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 AC3?
+
Yes. Drop a whole folder of WMA files; each becomes a separate AC3 and all are zipped for download.
Is the WMA to AC3 converter free?
+
Yes, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
