Upload your AAC 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 AAC to OGG a lossy or lossless conversion?
+
If both AAC 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 AAC 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 AAC to OGG conversion?
Does PDF.to support multi-channel (5.1, 7.1) AAC 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 AAC files to OGG?
+
Yes. Drop a whole folder of AAC files; each becomes a separate OGG and all are zipped for download.
Is the AAC to OGG converter free?
+
Yes, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
