Favicon Generator

How Favicon Generation Works

A favicon is the small icon browsers show in tabs, bookmarks, and history — but different devices and contexts actually need different pixel sizes of the same image: a browser tab typically uses 16×16 or 32×32, while a phone home-screen icon (Apple touch icon) needs a much larger 180×180. This tool takes your source image, resizes it down to each required dimension, and packages the full set together so you have every size a modern site typically needs, all generated from your one uploaded image, entirely in your browser.

Why Multiple Sizes Matter

Using a single small image and letting browsers scale it up produces blurry results on high-density displays or larger icon contexts. Generating each size natively from your original (larger) source image, rather than stretching a small one, keeps every size crisp. This is why the tool asks for a reasonably large source image and produces several output files rather than just one.

Common Mistakes to Watch For

• Uploading a low-resolution source image. If your original image is smaller than the largest required output size, that largest icon will end up blurry regardless of this tool — start with an image at least 512×512 for best results.
• Forgetting to link all generated files in your HTML. Simply having the files isn't enough — your site's <head> needs the corresponding <link> tags pointing to each favicon size for browsers to use them correctly.

When This Tool Helps — and When It Isn't Enough

Useful for quickly generating a complete favicon set for a website or web app. For simple, iconic designs (which favicons need to be, given their tiny display size), consider simplifying complex logos before uploading — intricate details are often lost at 16×16 pixels regardless of generation quality.

File Size & Browser Notes

The generated favicon package includes the standard sizes most browsers and devices expect (16×16, 32×32, 180×180, and more), so you don't need to manually resize your logo for each platform.
