AIFF to OGG Conversion FAQ
How do I convert AIFF audio to OGG without losing quality?
+
Upload the AIFF file and the converter chooses the OGG codec and bitrate to match the source. Lossless OGG (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy OGG (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears. AIFF stores uncompressed big-endian PCM — the Apple-side equivalent of WAV, with the same bit-for-bit fidelity. Vorbis inside OGG is lossy and uses variable bitrate by default, so quality is set as a level rather than a fixed kbps figure.
How much quality do I lose converting AIFF to OGG?
+
Some, and it is permanent — this is the one direction where information is genuinely thrown away. AIFF holds every sample exactly; OGG discards what a psychoacoustic model predicts you will not hear. At 192 kbps and above that prediction is good enough to be transparent on most material and most equipment. Keep the AIFF as your master, because you cannot get back to it from the OGG.
What bitrate will the resulting OGG file use?
+
Default is 192 kbps for lossy OGG; pass-through for lossless OGG. Override to 320 kbps for audiophile or 96 kbps for voice / podcast. The choice trades file size against audible fidelity; below 96 kbps lossy artifacts become noticeable on music.
Will going from AIFF to OGG reduce my audio quality?
+
If AIFF is lossy and OGG is lossless (e.g. MP3 → WAV), the OGG is no better than the AIFF — you cannot recover information already discarded. If AIFF is lossless and OGG is lossy, the OGG codec recompresses; at 192 kbps the result is transparent for most content.
Does the AIFF to OGG converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, and album art are read from the AIFF container and written into the OGG container where the format supports tags. All common targets (MP3, AAC, FLAC, OGG) handle tags fine; raw WAV does not. OGG is the Xiph.Org container, usually holding Vorbis audio, created in 2000 as a patent-free alternative to MP3.
Can I batch convert hundreds of AIFF files to OGG?
+
Yes — drop a folder of AIFF files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch finishes in minutes rather than tens of minutes.
Will the OGG keep the same sample rate as AIFF?
+
By default yes — 48 kHz AIFF stays 48 kHz in OGG. If you need to downsample for compatibility (96 kHz → 44.1 kHz for CD burning), the sample-rate option applies high-quality resampling in the same encode pass.
Can I normalize loudness when converting AIFF to OGG?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the OGG, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batching tracks mastered at varying levels.
Will my OGG play on car stereo, iPod, and Sonos?
+
MP3 plays everywhere. AAC plays on Apple, most Android, and Sonos. FLAC plays on Sonos and Android but not on older iPods. WAV plays on everything but is huge. The advanced device-preset dropdown picks an OGG codec optimized for your target hardware. OGG Vorbis beats MP3 at equal bitrate and carries no licensing cost, which is why game engines and open-source software adopted it wholesale. OGG has poor hardware support — car stereos, older iPods and many TVs will not see the file at all.
Is my AIFF file private during conversion to OGG?
+
Yes — uploaded AIFF files are processed in isolated workers and deleted within minutes. We never play back, store long-term, or share the audio content. The full retention window is in /privacy/.
How long does converting a 1-hour AIFF to OGG take?
+
Same-codec re-mux: 10 to 30 seconds. Re-encode to a different codec: typically 10 to 20% of source duration, so a 1-hour AIFF → OGG finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.
Why is the OGG louder or quieter than the AIFF source?
+
No automatic gain change happens unless you enable the normalize option. If you observe a level change, your audio player or media library is likely applying ReplayGain or per-track normalization on playback — not us. Disable that to hear the true OGG levels.
