Upload a square-ish image and get PNG favicons in every common size, ready to download. Processing happens entirely in your browser.
Tip: a square source image (e.g. 512×512) gives the cleanest result — non-square images are center-cropped to a square first.
No. Every size is generated locally in your browser using the Canvas API.
Rename the 32×32 or 48×48 PNG to favicon.ico (most modern browsers accept a PNG-formatted .ico), or use a dedicated .ico converter if you need a true multi-resolution ICO file. Then reference it with <link rel="icon" href="/favicon.ico"> in your site's <head>.
180×180 is Apple's touch icon size (iOS home screen), 192×192 and 512×512 are used for Android/Chrome and PWA manifests.
