HEIC vs ICO
Ein detaillierter Vergleich von HEIC Image und ICO Icon — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
HEIC Image
Raster & Vector ImagesHEIC is the default photo format on Apple devices since iOS 11. It offers roughly 50% better compression than JPEG at similar quality but has limited support outside the Apple ecosystem.
Über HEIC-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
HEIC Vorteile
- Roughly 50% smaller than JPEG at equivalent visual quality.
- 10- and 12-bit color depth supports HDR photography.
- Container format holds depth, Live Photo, bursts, and thumbnails in one file.
- Supports transparency and multi-image sequences.
- Built into iOS, macOS, and most modern Samsung and Google flagships.
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
HEIC Einschränkungen
- Patent-encumbered (HEVC) — Windows users must buy a $0.99 codec pack from the Microsoft Store.
- Not supported by most web browsers or older image editors.
- Sharing to non-Apple platforms usually auto-converts to JPEG, losing metadata.
- Hardware decoding required for smooth performance; software decoding is CPU-heavy.
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.
