The most common misconception about OGG: it's a container format like ZIP, not a codec. The Xiph codec family (Vorbis, Opus, FLAC, Speex) all live inside OGG. Why Spotify uses OGG Vorbis.
ABX blind tests show most listeners can't distinguish 192kbps from 320kbps. File size per song at each bitrate, streaming platform equivalents, VBR vs CBR, and why re-encoding never helps.
Converting CR2 permanently loses 14-bit color depth (8-bit JPEG can't store it). What you're giving up, JPEG quality settings by use case, and tools: Lightroom, RawTherapee (free), dcraw CLI.
GIFs are large because they use lossless LZW compression frame-by-frame with no inter-frame compression. The real solution: FFmpeg GIF→MP4 with HTML video tag. When to keep GIF anyway.

FLAC doesn't play in iTunes, most car stereos, or on hardware players. 320 kbps MP3 plays everywhere. The audiophile debate settled with actual ABX test data.
M4A is Apple's audio format — it sounds great on Apple devices, but fails on old car stereos, legacy Windows software, and hardware MP3 players. The fix is simple.

Scanned PDFs return empty output from standard tools — they need OCR. Digital PDFs extract instantly but multi-column layouts scramble text. The right tool for each case.
