How it works
ConvertCabin resizes your image to each icon size on a canvas and packs them into a single .ico file in your browser. Nothing is uploaded.
It stays free, unlimited and private, and works offline once loaded.
About Image to ICO
An .ico file can hold several sizes at once, which is exactly what browsers and Windows expect for favicons and app icons. A square source image gives the best result.
Frequently asked questions
How do I make a favicon?
Drop a square image, keep the default 16/32/48 sizes, and download the .ico — then drop it in your site root as favicon.ico.
Why are there multiple sizes?
Browsers and the OS pick the size they need; bundling several keeps the icon crisp everywhere.
Is my image uploaded?
No. The .ico is built on your device and never sent to a server.
What is an ICO file?
ICO is the Windows icon format. It packs several small square sizes (commonly 16, 32, and 48 pixels) into one file and is what browsers use for the favicon shown in tabs and bookmarks.
