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?
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, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
