HEIF vs ICO
Ein detaillierter Vergleich von HEIF Image und ICO Icon — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
HEIF Image
Raster & Vector ImagesHEIF (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.
Über HEIF-DateienICO Icon
Raster & Vector ImagesICO 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-DateienVorteilsvergleich
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.

HEIF (High Efficiency Image Dateiformat) is a Container Format based on HEVC Komprimierung, Standardized by MPEG in 2015. It can store still images, image sequences, und auxiliary data like depth maps. HEIC is the most common HEIF variant.
ICO (Icon) is Microsoft's 1985 multi-resolution icon Format, originally shipped mit Windows 1.0. A single .ico Datei holds multiple sizes (16×16, 32×32, 48×48, 256×256) so the OS can pick the best one für the current display context. Since 1999, every website uses a favicon.ico to show its icon in browser tabs.
