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.
Frequently asked questions
Which sizes are produced?
16, 32, 48, 96, 144, 180, 192, 256 and 512 pixel PNGs - covering browsers, Android, iOS and PWA install prompts.
Do I still need an ICO file?
Only for very old browsers. Modern browsers happily use PNG favicons declared in the page head.
What source image works best?
A square image of at least 512 pixels with a simple, high-contrast mark. Fine detail disappears at 16 pixels.
