About this conversion
Upload your logo or icon image, open "Details → Export presets", and click "Download favicon package". You’ll get a ZIP with favicon-16/32/48/192/512.png, an apple-touch-icon.png, and a real multi-resolution favicon.ico bundling the 16/32/48px sizes the way browsers expect. Works best with a simple, square source image.
Frequently asked questions
What files do I actually need on my website?
At minimum, favicon.ico in your site root plus a <link rel="icon"> tag; the additional PNG sizes and apple-touch-icon improve how your icon looks on high-DPI screens and iOS home screens.
Does my source image need to be square?
It works best that way -- this tool center-crops non-square images to a square before generating each size, which can cut off the edges of a wide or tall image.
Is a multi-size favicon.ico actually better than one PNG?
Yes -- bundling 16/32/48px in one .ico file lets the browser/OS pick the sharpest size for the context (browser tab vs. taskbar vs. bookmarks), rather than scaling one size up or down.
