Frequently Asked Questions
- What is an ICO file?
- ICO is a Windows icon container that bundles several pixel sizes of the same icon. The browser or OS picks the right size for each display context.
- Which sizes should I include?
- 16 and 32 are required for favicons. Add 48 and 64 for sharper Windows desktop icons on hi-DPI screens.
- Is the upload private?
- There is no upload. The PNG is read locally and the ICO is assembled in your browser.
