Why convert PNG to ICO?
- Transparent areas stay transparent: ICO supports smooth, partial transparency just like PNG.
- 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.
What to expect when converting PNG 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 PNG-fil ændres ikke: du downloader en ny ICO-kopi.
