Frequently Asked Questions

The .ico format is the classic Windows icon format and the standard for website favicons (favicon.ico). A single .ico can store several resolutions, so browsers and Windows can pick the right one for tabs, bookmarks, the taskbar or the desktop.

A good favicon.ico bundles multiple sizes — typically 16×16, 32×32, 48×48 and 256×256. This tool generates all of them in one file automatically, so it looks crisp everywhere from a browser tab to a Windows shortcut.

Start from a square PNG with a transparent background for the cleanest result. Non-square images are scaled to fit and centered on a transparent canvas. Simple, high-contrast logos read best at tiny 16px sizes.

No. The conversion to .ico happens entirely in your browser using the canvas API. Your file never leaves your device — no upload, no account, no limits.
