This tool generates a complete set of favicon files from an uploaded image — the small icon that appears in browser tabs, bookmarks, and on mobile home screens when a site is saved. It produces multiple sizes and formats needed for different browsers and devices, along with the HTML code to add them to a website.
A favicon might seem like a small detail, but it appears constantly — in browser tabs, bookmark lists, browser history, and as the icon when a site is added to a phone's home screen. Different contexts require different sizes: a tiny 16×16px icon for browser tabs, larger sizes for bookmarks and Android home screens, and a specific size for Apple's "add to home screen" feature on iOS. Providing only one size, or the wrong format, can result in a missing or blurry icon in some of these contexts.
<link> tags to your website's <head> sectionGeneration happens entirely in your browser — your image is never uploaded to a server.
Because favicons are displayed extremely small, simple designs work best — a single letter, initial, or simple icon is generally more recognisable at 16×16px than a detailed logo with fine text or intricate elements that become an unreadable blur at small sizes. High contrast between the icon and its background also helps visibility across both light and dark browser themes. If your logo is complex, consider creating a simplified version — perhaps just your brand's initial or a key symbol — specifically for use as a favicon.
It might seem like a single image should be able to scale to whatever size is needed, but small icon sizes have a unique challenge: at very small dimensions (16×16 or 32×32 pixels), there often aren't enough pixels to represent fine detail clearly, and naive scaling down from a larger image can produce a blurry or muddy result. Generating dedicated versions at each target size — rather than relying on a browser to scale one image down on the fly — allows each size to be optimised individually, ensuring the smallest sizes remain legible even though they have very few pixels to work with. This is part of why a favicon generator produces a whole set of files rather than just one image at the largest size.
Beyond browser tabs, favicons (or more specifically, larger versions of the same icon) serve an important role on mobile devices — when someone adds your website to their phone's home screen, the icon used is typically a larger version of your favicon, displayed at app-icon size alongside actual installed apps. This means your icon needs to hold up not just as a tiny tab icon, but also as something that looks reasonable sitting next to professionally designed app icons on a home screen. A design that works at both extremes — recognisable at 16×16px but also clean and not overly busy at 180×180px or larger — is the goal, which is part of why simple, bold designs tend to work better across the board than detailed ones.
After downloading the generated files, upload them to your website's root directory (or wherever your site structure expects them), and add the provided <link rel="icon"> tags to the <head> of your HTML pages. Browsers will then pick up the appropriate size automatically depending on context. Changes may take some time to appear due to browser caching of favicons — clearing your browser cache or testing in a private/incognito window can help confirm the new favicon is working.
A square image of at least 512×512px is recommended, giving the tool enough detail to generate all the smaller sizes needed without upscaling.
Typically an .ico file (which can contain multiple sizes) plus individual PNG files at various sizes for different devices and contexts, along with the HTML code needed to reference them.
Browsers cache favicons aggressively. Try a hard refresh, clear your browser cache, or test in a private/incognito window to see the updated icon.
Yes, favicons are square icons. If your logo isn't square, you may need to crop or adjust it first using Image Cropper.
No, generation happens entirely within your browser.
