Upload your AMR file and PDF.to re-encodes it into a OGG container with sensible default bitrate and sample-rate. The OGG download is ready in seconds.
Is AMR to OGG a lossy or lossless conversion?
+
If both AMR and OGG are lossless (WAV, FLAC, AIFF), no quality is lost. If OGG 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 OGG output use?
+
192 kbps by default for OGG 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 OGG?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when OGG supports it.
Will sample-rate and bit-depth survive the AMR to OGG conversion?
+
Da, privzeto. Mi ne spuščamo vzorca ali dither, razen če ga zahtevate v panelu z možnostmi. Za glas se lahko izberete v 22 kHz mono za zmanjšanje velikosti datoteke.
Can I convert a stereo AMR to mono OGG?
+
Da – preklopite možnost 'force mono'. To je koristno za podcaste in glasovne notice za približno polovično velikost datotek.
Does PDF.to support multi-channel (5.1, 7.1) AMR files?
+
Yes for OGG 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 OGG?
+
Yes. Drop a whole folder of AMR files; each becomes a separate OGG and all are zipped for download.
Is the AMR to OGG 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?
+
Št. PDF.to ne poskuša odstraniti DRM. Pretvorbe uspejo samo v nezaščitenih virnih datotekah.
Will the OGG I download play on iPhone, Android, and desktop?
+
Yes. OGG is supported natively across all major platforms or via universally available codecs. We default to the most-compatible OGG 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 OGG files are deleted within an hour.
