How It Works

This free online favicon generator resizes your image entirely in your browser — no file is ever sent to a server.

  1. 1. Upload your image

    Drop your logo or icon onto the upload area, or click to pick a file. PNG or SVG with a transparent background gives the cleanest results, but any image format works. Your file is read directly in your browser — nothing is transmitted anywhere.

  2. 2. Pick a background and padding

    Choose whether your favicon has a transparent, white, black, or custom background color. Use the padding slider to add a bit of space around your icon — useful if your logo sits edge-to-edge.

  3. 3. Choose the sizes you need

    All 9 standard sizes are pre-selected: 16×16 and 32×32 for browser tabs, 180×180 for Apple Touch icons, 192×192 for Android and PWA, and 512×512 for PWA splash screens. Uncheck any sizes you don't need.

  4. 4. Download your favicons

    Click Generate Favicons and preview each size. Download individual PNG files by hovering a tile and clicking Download, or click Download All (.zip) to get every size in one archive. The tool also shows you the exact HTML snippet to drop into your <head>.

Frequently Asked Questions

What is a favicon?
A favicon (short for "favourite icon") is the small icon shown in browser tabs, bookmarks, and address bars. Modern websites need multiple sizes to look sharp on different devices — from 16×16 for standard browser tabs to 512×512 for Progressive Web App splash screens.
What image should I use?
For best results, use a square PNG or SVG with a transparent background. Simple, high-contrast designs work best at small sizes. Avoid fine text or thin lines — they become illegible at 16×16.
Do I need an ICO file?
Modern browsers support PNG favicons, so ICO files are no longer required for most sites. The PNG files generated here are sufficient for all major browsers, Apple devices, Android, and PWAs.
Is this tool free to use?
Yes — completely free. No account, no credit card, no watermarks, no file size limits.
