Generate favicons in multiple sizes from one image. Perfect for websites and web apps.
The Favicon Generator creates favicon image files from your uploaded images in all the sizes required by modern browsers, mobile devices, and progressive web apps. Generate 16×16, 32×32, 64×64, 128×128, and 256×256 PNG favicons instantly, with a ZIP download option and ready-to-use HTML code — all without uploading anything to a server.
A favicon (short for "favorite icon") is the small icon that appears in browser tabs, bookmarks, browser history, and on mobile home screens when a website is saved as a shortcut. The Favicon Generator takes any image you upload and resizes it to all the standard favicon dimensions, producing a complete set of PNG files that you can drop directly into your website's root directory.
Modern websites need favicons in multiple sizes because different contexts display them at different resolutions. A browser tab uses a 16×16 or 32×32 pixel icon, while an iOS home screen shortcut uses a 180×180 pixel Apple Touch Icon, and a PWA splash screen may use a 512×512 pixel icon. Providing all sizes ensures your favicon looks sharp in every context rather than appearing blurry from browser upscaling.
The generator also produces the HTML link tags you need to add to your page's head section to reference all the favicon sizes correctly. This eliminates the need to look up the correct link tag syntax for each size and platform, saving time and reducing the chance of errors in your HTML markup.
Creating a complete favicon set from your image takes just a few clicks and produces everything you need for deployment.
Favicons are a small but important part of web presence and brand identity across many types of projects.
The most important factor for a good favicon is simplicity. At 16×16 pixels, there are only 256 pixels to work with, so complex logos with fine details, thin lines, or small text will become unrecognizable. The best favicons are bold, simple shapes or single letters with high contrast. If your logo is complex, consider creating a simplified version specifically for use as a favicon rather than using the full logo.
Square images produce the best results because favicons are displayed in square containers. If your source image is not square, the generator will stretch it to fit, which may distort your design. Crop your image to a square aspect ratio before uploading for the best output. A 512×512 or larger square source image gives the generator the most pixels to work with when downscaling to smaller sizes.
After generating and deploying your favicons, browsers may cache the old favicon for some time. To force a refresh during testing, you can append a query string to the favicon URL in your HTML (e.g., href="/favicon.ico?v=2"), which tells the browser to treat it as a new resource. In production, the favicon will update naturally as browser caches expire.
Creating favicons manually requires image editing software, knowledge of the required sizes, and the ability to export multiple files — a process that can take 10-15 minutes even for experienced designers. This generator reduces that to under a minute by automating the resizing and packaging steps. The included HTML code snippet eliminates another common source of errors by providing the exact markup you need.
Because all processing happens in your browser, there's no waiting for server-side processing and no risk of your images being stored or accessed by anyone else. This is particularly valuable when working with client logos or proprietary brand assets that you don't want to upload to third-party services. The tool is fast, private, and produces professional-quality results for any web project.
Your privacy is our priority. All processing happens entirely in your browser using JavaScript. No files, data, or inputs are ever uploaded to any server. Everything stays on your device, making this tool completely safe to use with sensitive content.
