Why convert BMP to ICO?
- One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.
- Browsere viser ICO-filen som dit websteds fane- og bogmærkeikon, når du gemmer den som favicon.ico.
What to expect when converting BMP to ICO
- Ikoner er kvadratiske, så et ikke-kvadratisk billede centreres på et gennemsigtigt kvadrat. Størrelser, der er større end dit billede, oprettes ikke, så start med mindst 256 × 256 pixels.
- Din originale BMP-fil ændres ikke: du downloader en ny ICO-kopi.
BMP vs ICO
| Funktion | BMP | ICO |
|---|---|---|
| Fulde navn | Windows Bitmap | Windows-ikon |
| Oprindelse | Created by Microsoft for Windows | Created by Microsoft for Windows icons |
| Komprimering | Ukomprimeret | Lossless images at several sizes |
| Gennemsigtighed | No (in the 24-bit BMPs most apps read) | Yes — smooth, partial transparency |
| Animation | Nej | Nej |
| Farve | 16,7 millioner farver (24 bit) | Fuld farve med gennemsigtighed |
| Hvor den kan åbnes | Windows and macOS apps, older software and browsers | Browsers (as favicon.ico), Windows and icon editors |
| Bedst til | older Windows programs, embedded devices and tools that need raw pixels | website favicons and Windows app or shortcut icons |
| Største ulempe | very large files and no transparency | icons are square and at most 256 × 256 pixels |
In short: choose BMP for older Windows programs, embedded devices and tools that need raw pixels; choose ICO for website favicons and Windows app or shortcut icons.
