OGG to AAC Conversion FAQ
How do I convert OGG to AAC audio?
+
Upload your OGG 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 OGG to AAC a lossy or lossless conversion?
+
If both OGG 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 OGG 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 OGG to AAC conversion?
+
Yes by default. We do not downsample or dither unless you ask for it in the options panel. For voice you can opt into 22 kHz mono to shrink file size.
Can I convert a stereo OGG to mono AAC?
+
Yes — toggle the 'force mono' option. This is useful for podcasts and voice memos to roughly halve file size.
Does PDF.to support multi-channel (5.1, 7.1) OGG files?
+
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 OGG files to AAC?
+
Yes. Drop a whole folder of OGG files; each becomes a separate AAC and all are zipped for download.
Is the OGG to AAC converter free?
+
Yes for files under 100 MB. PRO unlocks larger files (5 GB), parallel jobs, and higher bitrates.
Does the converter remove DRM from OGG files?
+
No. PDF.to does not attempt to remove DRM. Conversions only succeed on unprotected source files.
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 OGG files private during conversion?
+
Yes. Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the OGG and AAC files are deleted within an hour.
