Turn an image into a favicon set in all sizes - 16px to 512px PNG, favicon.ico and HTML tags
What is the Image to Favicon?
The image to favicon works like this: it turns a single uploaded image into the complete favicon set a modern website needs: PNG icons at 16 to 512px, a multi-size favicon.ico bundle, and the exact HTML tags to paste into your head section. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.
How to use the Image to Favicon
Click the upload area and choose a square image (PNG with transparency works best).
Use the live preview to check rounding and edge padding - padding keeps the icon from touching browser tab edges.
Press "Generate favicon set" - every size renders locally in your browser, nothing is uploaded.
Download the PNGs you need, the favicon.ico bundle, and copy the HTML snippet into your <head>.

Privacy
The URL you check is fetched once so the tool can read pages that block cross-origin browser requests. No browsing history is stored, and nothing from your own device is transmitted.
Frequently asked questions
Which files do I actually need?
favicon.ico in the site root covers legacy browsers; the PNG links plus a 180px apple-touch-icon and a webmanifest cover everything modern. The generated HTML snippet shows the exact tags.
Does my image need to be square?
No - any image is letterbox-fitted into a square canvas, but square source images stay sharpest.
What does the complete favicon set include?
PNG icons from 16px up to 512px, a multi-size favicon.ico bundle, an apple-touch icon and the HTML link tags - everything a modern site needs, generated from one uploaded image.
What image should I upload as the source?
A square PNG with transparency, at least 512x512 - the larger and cleaner the source, the sharper every generated size comes out.
