What Is a QR Code?
A QR (Quick Response) code is a 2D barcode that stores data like URLs, text, WiFi credentials, or contact info. Simply point your phone's camera at a QR code to scan it. They're widely used on business cards, restaurant menus, product packaging, event tickets, and marketing materials.
Common Uses for QR Codes
- Business cards · Share your contact info (vCard) that saves directly to the scanner's phone.
- Restaurant menus · Link to a digital menu that's always up to date.
- WiFi sharing · Let guests connect to your WiFi without typing the password.
- Marketing & flyers · Drive traffic to your website, app store listing, or social media.
- Product packaging · Link to manuals, warranty registration, or reviews.
- Event tickets · Encode ticket data for fast check-in at the door.
Frequently Asked Questions
What's the best size for a QR code?
For print, make sure the QR code is at least 2 cm x 2 cm (about 0.8 inches). For billboards or signs viewed from a distance, scale up proportionally. The rule of thumb is: scanning distance divided by 10 equals minimum QR code size.
PNG or SVG · which should I download?
Use PNG for digital use (websites, social media, emails). Use SVG for print materials · SVG is a vector format that scales to any size without losing quality.
Can I customize the colors?
Yes! Use the foreground and background color pickers to match your brand. Just make sure there's enough contrast between the two colors for reliable scanning.
Do QR codes expire?
No. QR codes generated here are static · the data is encoded directly in the pattern. They will work forever as long as the content they link to (like a URL) remains active.
