About the Favicon Generator (All Sizes)
A favicon is the small icon shown in browser tabs, bookmarks, and mobile home screens, but modern websites actually need many different icon sizes to look correct across browsers, iOS home screens, Android, and Windows tiles. This generator takes a single source image and automatically produces every commonly required favicon size, packaged into a single downloadable zip.
This tool is useful for web developers setting up a new site's favicon correctly for the first time, designers converting a logo into a proper icon set, and site owners who only have a single square logo image and need the full range of standard sizes without manually resizing each one.
To use it, upload a square source image (ideally at least 512×512px for best quality across all output sizes), and the tool automatically generates 16×16, 32×32, 48×48, 180×180 (Apple touch icon), 192×192 and 512×512 (Android/PWA) PNG versions, plus a combined favicon.ico file. Download everything as a single zip, along with a ready-to-paste HTML snippet linking each file correctly in your page's <head>.
For example, uploading a 1024×1024px logo produces a complete set from a tiny 16×16 browser tab icon up to a 512×512 icon used for Android home screen shortcuts and progressive web apps, ensuring your brand looks crisp and correctly sized on every device and browser rather than being oddly stretched or cropped from a single mismatched size.
A common mistake is uploading a non-square or very low-resolution source image, which produces blurry or oddly-cropped results at larger output sizes — always start with a square, high-resolution image (ideally a simplified version of your logo that remains legible even at 16×16 pixels, since intricate details are lost at the smallest sizes). Another frequent issue is forgetting to actually link the generated files in the HTML head, since simply placing favicon.ico in your root directory alone doesn't cover the Apple touch icon and Android icons that most modern browsers and devices also look for.
Tip: design your source logo with small-size legibility in mind — a simplified icon or monogram (rather than a detailed illustration or long wordmark) will remain recognizable even at the tiny 16×16 pixel size used in browser tabs.
