A favicon is the small icon in browser tabs, bookmarks, and browser history — and a missing or broken one can make even a polished site look unfinished. Use our free Favicon Generator to create a complete favicon package from any image.
What Is a Favicon and Why Does It Matter?
The favicon is often the first visual detail a user notices when they have multiple tabs open or scroll through their bookmarks. It reinforces brand recognition at a glance and signals that a site is complete and professionally maintained. Without one, browsers show a generic placeholder — which reads as unfinished even when the site itself is excellent.
Why Multiple Sizes Are Needed
Browser tabs typically use 16×16 or 32×32 pixel icons. iOS home screen bookmarks expect a 180×180 Apple touch icon. Android and PWA installs use 192×192 and 512×512 sizes. Using a single image scaled to every context often produces blurry icons or awkward cropping on some devices. A proper favicon package includes all standard sizes, each generated at the correct resolution.
Design Tips for Small Sizes
A simple, recognizable shape works far better at 16×16 than a detailed logo with fine lines and small text. Bold shapes with strong contrast remain legible at tiny sizes. If your full logo is complex, consider using a simplified mark or monogram for the favicon while keeping the full logo elsewhere on the site.

Frequently Asked Questions
What image size should I start with for a favicon?
Starting with a square image at least 512x512px gives the generator enough resolution to produce all the smaller sizes cleanly without quality loss.
Why do I need multiple favicon sizes instead of just one?
Different platforms and contexts (browser tabs, iOS home screen bookmarks, Android app icons) expect specific sizes, and using a single size everywhere often results in blurry or oddly-cropped icons on some devices.
Where do I add the generated favicon to my website?
Place the favicon files in your site's root or assets folder, then add the provided <link> tags inside your HTML <head> section, exactly as given by the generator.
Will a detailed logo work well as a favicon?
Complex or detailed logos often become illegible at small sizes like 16x16px — simpler, bold shapes with strong contrast tend to remain recognizable even at tiny favicon sizes.
