Why convert JPG 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 JPG 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 JPG-fil ændres ikke: du downloader en ny ICO-kopi.

In short: choose JPG for photos you share, email, print or upload; choose ICO for website favicons and Windows app or shortcut icons.
