Upload your AMR file and PDF.to re-encodes it into a MP2 container with sensible default bitrate and sample-rate. The MP2 download is ready in seconds.
Is AMR to MP2 a lossy or lossless conversion?
+
If both AMR and MP2 are lossless (WAV, FLAC, AIFF), no quality is lost. If MP2 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 MP2 output use?
+
192 kbps by default for MP2 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 AMR to MP2?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when MP2 supports it.
Will sample-rate and bit-depth survive the AMR to MP2 conversion?
Does PDF.to support multi-channel (5.1, 7.1) AMR files?
+
Yes for MP2 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 AMR files to MP2?
+
Yes. Drop a whole folder of AMR files; each becomes a separate MP2 and all are zipped for download.
Is the AMR to MP2 converter free?
+
Yes, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
Does the converter remove DRM from AMR files?
+
No. PDF.to 不试图删除 DRM。 转换仅在未保护源文件上成功 。
Will the MP2 I download play on iPhone, Android, and desktop?
+
Yes. MP2 is supported natively across all major platforms or via universally available codecs. We default to the most-compatible MP2 profile.
Are my AMR files private during conversion?
+
Yes. Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the AMR and MP2 files are deleted within an hour.
