HEIF

HEIF Image

Raster & Vector Images

HEIF (High Efficiency Image File Format) is the container format behind HEIC. It supports advanced features like image sequences, depth maps, and HDR but has limited cross-platform support.

ICO Icon

Raster & Vector Images

ICO is the icon file format used for favicons and Windows application icons. A single ICO file can contain multiple image sizes and color depths for different display contexts.

Über ICO-Dateien

Vorteilsvergleich

HEIF Vorteile

  • ~50% smaller than JPEG at equivalent quality, with better detail retention.
  • Container holds multi-image bursts, depth maps, and HDR data in one file.
  • Supports 10 and 12-bit color, wide gamut, and HDR out of the box.
  • Default iPhone camera format since 2017 — billions of files in existence.

ICO Vorteile

  • Multi-resolution: one file, many sizes, OS picks the right one.
  • Universal favicon support in every browser since IE5.
  • Supports transparency (1-bit since 1985, full alpha since XP).
  • Tiny file size — an entire favicon pack typically fits in under 15 KB.
  • No licensing or patent concerns — fully in the public domain spec-wise.

Einschränkungen

HEIF Einschränkungen

  • HEVC codec inside .heic is patent-encumbered — licensing fees steered the web toward AVIF.
  • Windows, Android, and most email clients needed plugins or recent updates to open HEIC.
  • Encoding is CPU-intensive on older hardware.
  • Fragmented ecosystem — the same file extension (.heif) can hold incompatible codecs.

ICO Einschränkungen

  • Cannot compress continuous-tone images efficiently — use PNG or WebP for photos.
  • Format is essentially frozen in 1999 — no HDR, no wide gamut, no modern features.
  • Maximum image dimension is 256×256 px (inside an ICO container).
  • Editing requires specialized tools — most image editors treat it as a curiosity.
