Upload your M4R file and PDF.to re-encodes it into a WAV container with sensible default bitrate and sample-rate. The WAV download is ready in seconds.
Is M4R to WAV a lossy or lossless conversion?
+
If both M4R and WAV are lossless (WAV, FLAC, AIFF), no quality is lost. If WAV 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 WAV output use?
+
192 kbps by default for WAV 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 M4R to WAV?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when WAV supports it.
Will sample-rate and bit-depth survive the M4R to WAV conversion?
Does PDF.to support multi-channel (5.1, 7.1) M4R files?
+
Yes for WAV 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 M4R files to WAV?
+
Yes. Drop a whole folder of M4R files; each becomes a separate WAV and all are zipped for download.
Is the M4R to WAV converter free?
+
Yes, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
