A QR code (short for Quick Response code) is a type of scannable barcode that stores data like URLs, contact details, or plain text. When someone scans a QR code using a smartphone camera or QR scanner, they’re instantly directed to the embedded information—often a website. This creates a seamless bridge between offline and online experiences. For example, a flyer or product packaging can take someone directly to a product page with a simple scan.

QR codes work using black-and-white pixel patterns that encode digital information. They’re extremely versatile and can link to anything from sign-up forms to downloadable guides.

Common uses of QR codes in web design

QR codes can be integrated into web design in a few creative ways. Many businesses use them to guide customers to contact forms, booking pages, or even special discount landing pages. If you're running an event, you might embed a QR code on your site or emails that lets attendees check in or view a digital ticket.

They're also great for connecting printed marketing to your digital content. For example, print ads can include QR codes that lead to your blog or showcase portfolio. And for mobile users, it's often more convenient to scan a QR code than type in a long URL.

Benefits of using QR codes

QR codes boost accessibility, especially for mobile users. Instead of relying on someone to type in a link, they can scan and land on your desired page in seconds. This is especially useful when promoting your SEO pages or product features in physical formats like business cards or posters.

They’re also trackable. You can measure how many times a QR code has been scanned, which gives you insights into user behavior. And since they’re so easy to generate, they offer a low-cost way to drive traffic to specific pages or actions.

Best practices for using QR codes on your website

When adding QR codes to your website, make sure they’re sized properly and easy to scan. Avoid placing them in hard-to-reach corners or overlaying them on busy backgrounds. Always test your QR code with a phone before publishing to ensure it leads to the correct destination.

It’s also smart to use a URL shortener or QR code generator that offers scan analytics. This gives you helpful data, like how many people are using your codes and from where. Lastly, be clear about what happens when someone scans the code—whether it leads to a coupon, a booking form, or a new blog post.

How to create a QR code

Creating a QR code is super simple. There are tons of free QR code generators online where you just paste your link, and the tool creates a downloadable image file. Some allow customization—like changing colors or adding a logo to match your branding.
