Every size is rendered on your device — nothing is uploaded
About Favicon Generator
A favicon is the smallest piece of branding on the web and one of the most visible - it identifies your tab, your bookmark and your installed app icon.
Upload one square image and this generator renders every size a modern site needs, packages them for download and writes the matching link tags and web app manifest entries for you.
How Favicon Generator works in your browser
Your source image is drawn onto canvases at 16, 32, 48, 96, 144, 180, 192, 256 and 512 pixels and exported as PNGs, covering browser tabs, iOS home screens, Android and PWA install icons.
The generator also writes the matching link tags and web app manifest entries. Fine detail vanishes at 16 pixels, so a simple, high-contrast square mark works best.
When to use it
- Creating every icon size a new website needs from one logo.
- Generating PWA manifest icons for an installable web app.
- Replacing a blurry favicon with properly sized versions.
