Enter the content you want to encode in your QR code. This could be a website URL, contact information, plain text, or other data.
QR Code Size: 200px × 200px
QR codes (Quick Response codes) are two-dimensional barcodes that can store various types of information and be scanned with a smartphone camera.
QR codes were invented in 1994 by Denso Wave, a subsidiary of Toyota, to track vehicles and parts during manufacturing. The "QR" stands for "Quick Response," as they were designed to be decoded quickly.
Unlike traditional barcodes that can only store information horizontally, QR codes store data both horizontally and vertically, allowing them to hold significantly more information in a smaller space.
Today, QR codes have become ubiquitous worldwide, used for everything from contactless payments and digital menus to marketing campaigns and access control systems.
QR codes consist of black squares arranged on a white square grid. They include several key elements:
The three large squares at the corners help scanners identify the QR code and its orientation.
Smaller squares throughout the code help ensure proper scanning, especially for larger or distorted codes.
Alternating black and white patterns that help determine individual cell coordinates.
The main area of the QR code contains the encoded data along with error correction information.
Static QR codes contain fixed information that cannot be changed after generation. They are ideal for:
Direct scanners to your website or specific landing pages.
Share name, phone, email, and address that can be saved to contacts.
Encode network name and password for easy connection.
Dynamic QR codes allow you to change the destination or content without creating a new QR code. They typically point to a redirect URL that can be updated.
Update campaign destinations even after materials are printed.
Restaurants can update menu content without replacing QR codes.
Monitor scan counts, locations, and devices to measure engagement.
Process payments through digital wallets, requiring no physical contact.
Link to detailed specs, user manuals, or authenticity verification.
Event tickets, airline boarding passes, and venue access.
Track product locations, movement, and authenticity throughout supply chains.
Print QR codes at least 2 × 2 cm (about 0.8 inches) for reliable scanning. For greater distances, increase the size proportionally.
Always leave a white border (called the quiet zone) around your QR code. This margin should be at least four times the width of one module (dot).
Maintain high contrast between the foreground and background colors. Dark modules on a light background work best, with black on white being optimal.
Always test your QR codes with multiple devices before printing or distributing them to ensure they scan properly.
The more data you put in a QR code, the more complex and harder to scan it becomes. Use URL shorteners for long web addresses.
Since QR codes are typically scanned with mobile devices, ensure that linked websites are optimized for mobile viewing.
Include text or instructions near your QR code to inform users what they'll get by scanning it.
For QR codes in outdoor or high-traffic areas, use higher error correction levels to ensure they remain scannable even if slightly damaged.

Test on Multiple Devices: Always verify your QR code works on different phones and scanning apps.
Add a Call-to-Action: Include text like "Scan me for..." near your QR code.
High Contrast is Key: Dark foreground on light background scans best.
• Making QR codes too small to scan properly
• Not providing context for what the QR code does
• Using low contrast colors that are difficult to scan
• Placing QR codes where they're difficult to access
• Not testing the QR code before distribution
