Favicon Generator
Turn any image into a complete favicon package — favicon.ico, PNGs, manifest and the HTML — privately in your browser.
How to favicon generator in 3 steps

Frequently asked questions
Are my images uploaded to a server?
No. Every operation runs entirely inside your browser using your device's own processor. Your files never leave your computer, so the tool works even with the page disconnected from the internet after loading.
What's in the download?
A ZIP with a multi-resolution favicon.ico (16/32/48), PNGs from 16×16 up to 512×512 (including apple-touch-icon and Android Chrome sizes), a site.webmanifest, and an HTML snippet to paste into your <head>.
What image should I use?
A square image works best — ideally a simple logo or icon that stays recognisable when small. A transparent PNG gives the cleanest result.
How do I install the favicon?
Copy the files to your site's root and paste the included HTML snippet into the <head> of your pages. The snippet links the .ico, the PNGs and the manifest.
Does the favicon.ico contain multiple sizes?
Yes. The generated favicon.ico embeds 16×16, 32×32 and 48×48 versions so browsers pick the sharpest one for each context.
