What you can encode in a QR code
A QR code can store any text up to several hundred characters. Common uses include website URLs, contact information (vCard), plain text messages, email addresses, phone numbers, Wi-Fi network credentials, and app store links. Keep the text short for better scan reliability on small printed sizes.
Popular use cases
Business cards: Add a QR code that links to your website or LinkedIn profile so contacts can find you instantly with a phone scan.
Restaurant menus: Link to a digital menu so customers can view it on their phone without handling a physical menu.
Wi-Fi sharing: Encode your network name and password so guests can join without typing credentials. Format the text as: WIFI:S:NetworkName;T:WPA;P:Password;;
Event check-in: Link to a registration or RSVP page for quick mobile access at the door.
Product packaging: Link to instructions, warranty registration, or a product landing page directly from the box.
Print to digital: Add a QR code to flyers, posters, or brochures so readers can visit your website without typing a long URL.
Tips for best results
Use short URLs or a link shortener to make QR codes less dense and easier to scan. Print at a minimum of 2 by 2 centimeters. Test the QR code with multiple devices before printing. Add a short label beneath the code such as "Scan to visit our website" to encourage people to use it.
Frequently asked questions
- Do QR codes expire?
- No. A QR code encodes your content directly and will always decode to the same text. If you linked to a URL, the QR code works as long as that webpage is still online.
- Is there a character limit?
- QR codes can technically store up to around 4,000 characters, but for reliable scanning keep content under 200 characters. Shorter content produces a simpler pattern that scans faster.
- Can any phone scan QR codes?
- Yes. Most modern smartphones can scan QR codes using the built-in camera app without needing a separate app. Open your camera, point it at the QR code, and tap the notification that appears.
- Is the QR code stored on your servers?
- No. The QR code is generated entirely in your browser using JavaScript. Nothing is uploaded or saved anywhere.
