Question 1

What sizes does a favicon need to be?

Accepted Answer

Modern websites typically need favicons at multiple sizes: 16x16 and 32x32 for standard browser tabs, 180x180 for Apple Touch Icon on iOS devices, 192x192 and 512x512 for Android Chrome, and 48x48 for Windows site icons. An ICO file containing multiple sizes (16x16, 32x32, 48x48) is the traditional format. Our tool generates all of these automatically from your single source image.

Question 2

What file format should my source image be?

Accepted Answer

Any common image format works — JPEG, PNG, WebP, SVG, or even a GIF. For the best results, use a PNG with a transparent background and a simple design. Complex designs with fine details may not be legible at small sizes like 16x16 pixels, so a simplified version of your logo typically works better than a full detailed version.

Question 3

Why does my favicon look blurry on some devices?

Accepted Answer

Blurry favicons usually result from using a low-resolution source image or missing size variants. A favicon needs to look crisp at 16x16 pixels, which means the source image should have enough detail to be recognizable at that size. Our tool generates separate files at each required size, ensuring sharp rendering on every device. If your current favicon looks blurry, try using a higher-resolution source image.

Question 4

How do I add a favicon to my website?

Accepted Answer

Place the favicon files in your website's root directory or in a dedicated /favicon/ folder. Add the appropriate link tags to the section of your HTML: for the ICO file, for PNG variants, and for iOS. Our tool provides the exact code snippets you need.

Question 5

Can I use an SVG as a favicon?

Accepted Answer

Yes. SVG favicons are supported by modern browsers and offer the advantage of being infinitely scalable. They look crisp at any size and typically have very small file sizes. However, not all browsers support SVG favicons yet, so it is best practice to provide both SVG and PNG fallbacks. Our tool generates PNG variants that work across all browsers.

Question 6

Do I need to regenerate my favicon after a brand update?

Accepted Answer

Yes. Whenever your logo or brand identity changes, you should regenerate your favicons to match. Update the source image with your new brand mark and run it through the generator. Then replace the old favicon files on your server with the new ones. Browsers cache favicons aggressively, so you may need to add a version parameter (e.g., /favicon.ico?v=2) to force browsers to load the updated version.
