About Favicon Generator
The Favicon Generator turns any image into the small icons that appear in browser tabs, bookmarks, and shortcuts. It produces several standard sizes at once so your site looks sharp on everything from a phone tab to a high-resolution desktop display.
All resizing happens in your browser with the canvas, so your source artwork is never uploaded. That gives you a quick, private way to brand your website without design software or signup.
How to Use Favicon Generator
- Click the upload area and select an image, ideally a square one.
- Click Generate Favicons to create the 16, 32, 64, and 128 pixel versions.
- Preview each size to make sure your icon stays clear and recognizable.
- Click Download All to save every favicon size as a PNG file.

Frequently Asked Questions
What image works best for a favicon?
A square image gives the best results because favicons are square. Simple logos or icons with bold shapes stay recognizable even at 16x16 pixels.
Which favicon sizes are generated?
The tool creates 16x16, 32x32, 64x64, and 128x128 pixel versions, covering browser tabs, bookmarks, and high-resolution displays.
Are my images uploaded to a server?
No. Favicons are generated locally in your browser using the canvas, so your source image never leaves your device.
How do I add the favicon to my website?
Download the PNG sizes and link the appropriate one in your HTML head with a link rel=icon tag that points to the file.
