How do I convert Opus to AMR audio?
+
Upload your Opus 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 Opus to AMR a lossy or lossless conversion?
+
If both Opus 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 Opus 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 Opus to AMR conversion?
+

Does PDF.to support multi-channel (5.1, 7.1) Opus 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 Opus files to AMR?
+
Yes. Drop a whole folder of Opus files; each becomes a separate AMR and all are zipped for download.
Is the Opus 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 Opus files?
+
E le o taumafai le PDF.to e aveese le DRM. E manuia ai le toe faʻavasegaina o faila faʻavae e le puipuia.
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 Opus files private during conversion?
+
Yes. Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the Opus and AMR files are deleted within an hour.
