A favicon is the small icon shown in a browser tab, bookmarks list, and mobile home screen shortcut. This tool takes any image you upload and resizes it into the common favicon dimensions — 16×16, 32×32, 48×48, and 180×180 for Apple touch icons — all generated locally in your browser.
For best results, start with a simple, square, high-contrast image, since fine detail tends to disappear at the smallest sizes.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.
Bookmark this page if you expect to use this tool regularly — it loads fast and behaves the same way every time, with no account needed.
This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this conversion or calculation often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.

Because the calculation or conversion happens instantly as you type, you can experiment freely and see how changing one value affects the result.
For recurring tasks, having a single dependable tool beats re-deriving the same calculation or formatting by hand every time.
Many people discover a tool like this the first time they need it for a specific task, then come back to it regularly afterward once they know it exists.
