AIFF to OGG Conversion FAQ
How do I convert AIFF to OGG audio?
+
Upload your AIFF 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 AIFF to OGG a lossy or lossless conversion?
+
If both AIFF 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 AIFF 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 AIFF to OGG 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 AIFF to mono OGG?
+
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) AIFF 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 AIFF files to OGG?
+
Yes. Drop a whole folder of AIFF files; each becomes a separate OGG and all are zipped for download.
Is the AIFF to OGG 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 AIFF files?
+
No. PDF.to does not attempt to remove DRM. Conversions only succeed on unprotected source files.
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 AIFF files private during conversion?
+
Yes. Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the AIFF and OGG files are deleted within an hour.
