About Favicon Generator
Create a favicon from an image in your browser and download a PNG favicon in a standard size. NeroTool keeps this workflow simple and browser-based. Where supported, processing happens locally in your browser.
How to use this tool
Upload an image, choose a target size, then select Generate favicon. Download the resulting PNG and add it to your website's HTML or hosting configuration.
Why simple designs work best at small sizes
A favicon is often displayed at 16 to 32 pixels, far smaller than a typical logo. Detailed artwork or small text tends to blur into an unrecognizable smudge at that size, so a single bold shape, letter or symbol usually stays legible better than a direct shrink of a full logo.

Frequently asked questions
What image format should I use for a favicon?
A PNG with a transparent background generally works well, since browsers display it directly without additional conversion.
What size should a favicon be?
Common sizes range from 16x16 to 32x32 pixels for browser tabs, with larger sizes sometimes needed for bookmarks and home screens.
Why does my favicon look blurry?
This usually happens when a detailed image is shrunk down too far; simplifying the design before generating the favicon helps.
Is my image uploaded to a server?
Processing happens in your browser, so the image is not intentionally sent to a NeroTool server.
