AMR ka AAC FAQ Konversi
How do I convert AMR to AAC audio?
+
Upload your AMR file and PDF.to re-encodes it into a AAC container with sensible default bitrate and sample-rate. The AAC download is ready in seconds.
Is AMR to AAC a lossy or lossless conversion?
+
If both AMR and AAC are lossless (WAV, FLAC, AIFF), no quality is lost. If AAC 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 AAC output use?
+
192 kbps by default for AAC 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 AAC?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when AAC supports it.
Will sample-rate and bit-depth survive the AMR to AAC conversion?

+
Yes for AAC 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 AAC?
+
Yes. Drop a whole folder of AMR files; each becomes a separate AAC and all are zipped for download.
Is the AMR to AAC 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 teu ngacobaan ngaleupaskeun DRM. Konversi ngan bisa réngsé dina berkas sumber anu teu dilindungi.
Will the AAC I download play on iPhone, Android, and desktop?
+
Yes. AAC is supported natively across all major platforms or via universally available codecs. We default to the most-compatible AAC 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 AAC files are deleted within an hour.
