About Favicon Generator

Build a complete favicon and app-icon pack — ICO, PNG sizes, Apple touch icon and ready-to-paste HTML — from a single source image.

A favicon pack uses several sizes because browsers, bookmarks and mobile home screens render icons in different contexts. Start with a square, high-resolution source for the clearest results.

What the result contains

A separate result that build a complete browser and app icon pack from one image. The source remains unchanged in the current browser session.

Supported formats

  • PNG
  • JPG
  • WEBP
  • SVG+XML
  • SVG

How to use Favicon Generator

  1. Choose a source file in a supported format (PNG, JPEG, WEBP, SVG+XML, .SVG) and confirm the displayed file details.
  2. Prepare the available controls for this practical goal: Add a professional favicon set to a new website
  3. Run Favicon Generator and confirm that the new result matches the stated outcome before saving it.
  4. Check this known constraint before download: A square, high-resolution source image gives the clearest results at small sizes If needed, revise the settings and create another version from the retained source.
Practical example

Add a professional favicon set to a new website. Use a representative source, compare the output with the original, and keep the version that meets the destination's requirements.

When to use Favicon Generator

  • Add a professional favicon set to a new website
  • Refresh outdated icon files across browser tabs and bookmarks
  • Generate home-screen icons for a web app

Important limitations

  • A square, high-resolution source image gives the clearest results at small sizes
  • Extremely detailed artwork can lose clarity once scaled down to 16×16

Troubleshooting Favicon Generator

The result is different from what you expected

A square, high-resolution source image gives the clearest results at small sizes Return to the retained source, adjust the relevant setting and create a fresh result rather than repeatedly processing the output.
