A favicon is a small icon that appears next to your page title in browser tabs. Although tiny, a favicon plays an important role in brand building and improving the user experience. The right icon can boost site recognition and make navigation easier for visitors, making it an essential element for every modern website.
What is a favicon and why does it matter?
A favicon is a small icon that appears next to the page title in browser tabs, on cards, and in the address bar. It not only helps users quickly identify a website, but also contributes to the visual identity of the brand. A favicon is therefore an important element of web design.
History of the favicon
The first favicons appeared in 1999, and their role in web design has changed significantly since then. Originally just a small icon for bookmarks, a favicon today is part of a broader visual branding concept. Over time, favicons have become an integral part of professional websites and online stores.
Functions of a favicon
A favicon serves several key functions.
- Site identification — a favicon lets users easily recognize your page among multiple open tabs.
- Increased credibility — websites with a professionally designed icon look more serious and trustworthy.
- SEO benefits — while a favicon doesn’t directly affect search rankings, it contributes to the overall visual impression of the site, which can indirectly improve the user experience.
Impact on the user experience
A favicon improves the user experience by making navigation easier and providing greater clarity. If a site has a visible, memorable favicon, users will return more easily. This small but important element can have a big impact on overall visitor satisfaction.
How to design a memorable favicon
Designing a favicon should be part of the overall web design process, as it affects the brand’s visual identity. A favicon should be simple, easily recognizable, and memorable. This tiny icon must work at very small dimensions, which is a challenge for any designer.
Technical requirements and formats
A favicon is typically in PNG, ICO, or SVG format, each with specific advantages. The most commonly used format is ICO because it’s compatible with most browsers. For modern sites, SVG is ideal because it’s vector-based and can be scaled without loss of quality.
- PNG format — recommended for favicons with a transparent background.
- ICO format — a traditional format supporting multiple sizes.
- SVG format — suitable for vector graphics and modern browsers.
Optimization for different platforms and browsers
When designing a favicon, remember it appears across different devices and platforms, requiring optimization for various sizes. It’s important to create multiple versions for different resolutions (for example, 16 x 16 px, 32 x 32 px, 64 x 64 px). Without proper optimization, a favicon may appear blurry or illegible on some devices.
- Desktop version — the recommended size is 16 x 16 px for browser tabs.
- Mobile version — mobile icons typically need 192 x 192 px for Android and 180 x 180 px for Apple devices.
- High‑definition displays — for Retina displays, provide higher‑resolution favicons.
Design tips: simple and memorable
A favicon should be visually clean and simple, as there’s limited space to display details. Avoid complex details or text, which will be lost when scaled down. Instead, the favicon should represent your logo or brand initials in the simplest possible form.
- Minimalism — use a single element clearly associated with your brand.
- Brand consistency — the icon should match your site’s overall design.
- Bold colors — choose contrasting colors to help the favicon stand out among other tabs.
Favicon in practice: inspiration and what to focus on
Using a favicon is a standard part of modern web design and helps build a strong visual brand identity. Many well‑known brands use simple yet effective favicons that stick in users’ minds. Remember that a favicon matters not only aesthetically, but also in practical use—such as in bookmarks or when added to a mobile device’s home screen.
Examples of successful favicons
Some brands excel at favicons—their icons are models of simplicity and effectiveness. Apple, Twitter, and Google are examples of companies with unmistakable favicons that are perfectly aligned with the brand. Even when reduced to very small sizes, they remain recognizable and effective.
- Apple — the apple‑shaped icon is instantly recognizable and retains its identity even on small screens.
- Twitter — the simple bird on a blue background is highly visible and works in any context.
- Google — a minimalist “G” in multiple color variants that remains clearly identifiable at small sizes.
Other overlooked elements to make your site stand out
Beyond the favicon, there are other small enhancements that can improve and highlight your site. One example is a thoughtfully designed 404 page, which not only informs users about an error but can also entertain them and keep them on the site. Another overlooked element is personalized device and bookmark icons that appear when users add your site to their home screen.
- 404 page — a fun or creative error page can draw attention and show your brand’s human side.
- Personalized icons — iOS and Android icons can complement your aesthetics and improve the user experience.
- Microinteractions — small animations or effects during interactions can leave a strong impression and increase engagement.
