QR Code

QR codes bridge the gap between physical and digital experiences. A customer scans a code on your product packaging and lands on a support page. A restaurant patron scans a table code and opens your menu. A conference attendee scans your badge and gets your contact details. The use cases are nearly limitless.

Global QR code usage has grown over 400% since 2020, driven largely by the pandemic-era shift toward contactless interactions. According to Statista, over 89 million smartphone users in the US alone scanned a QR code in 2024, up from 72 million in 2022.

For customer-facing businesses, QR codes simplify the path between a customer's problem and your solution. Instead of asking someone to type a URL, search for your app, or navigate a phone menu, you hand them a scannable code that takes them exactly where they need to go. This reduces friction and improves the support experience.

This generator creates static QR codes — the data is encoded directly into the image. They work offline, never expire, and don't depend on any tracking service. You can generate codes for URLs, plain text, email drafts, phone numbers, and WiFi networks.

How to Use This Generator

  1. Select the data type: Choose URL, Text, Email, Phone, or WiFi from the tabs above.
  2. Enter your content: Type or paste the data you want to encode. For WiFi, enter the network name, password, and encryption type.
  3. Customize appearance: Optionally change the QR code size and foreground/background colors. Ensure high contrast for reliable scanning.
  4. Preview and download: The QR code generates automatically. Click "Download PNG" to save the image.

Test your QR code by scanning it with your phone camera before using it in print materials.

Pro Tips

  • Use short URLs: Shorter data produces simpler QR codes that are easier to scan, especially at small sizes. Use a URL shortener for long links.
  • Add a call-to-action: Don't just display a QR code — add text like "Scan for support" or "Scan to connect to WiFi" so people know what to expect.
  • Test before printing: Always scan your QR code with at least two different phones before committing to print. Test from the expected scanning distance.
  • Maintain quiet zone: Leave white space (at least 4 modules wide) around the QR code. Cropping too close to the code makes it harder to scan.
  • Prefer dark on light: Dark foreground on white or light background is the most reliable combination. Some older phone cameras struggle with inverted (light on dark) codes.

Frequently Asked Questions

What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores data such as URLs, text, or contact information. When scanned with a smartphone camera, it instantly opens the encoded content — a website, email draft, phone call, or WiFi login. QR codes were invented by Denso Wave in 1994.
What types of data can a QR code store?
QR codes can encode URLs (websites), plain text, email addresses (with subject and body), phone numbers, WiFi network credentials, vCard contact cards, calendar events, and geographic coordinates. Business uses include linking to product pages, menus, support portals, and payment systems.
What size should a QR code be for printing?
For business cards, use at least 2×2 cm (0.8 inches). For posters, minimum 3×3 cm. For billboards or signage meant to be scanned from a distance, 10+ cm. The general rule: the scanning distance in centimeters divided by 10 gives you the minimum QR code size in centimeters.
Do QR codes expire?
Static QR codes (like the ones this tool generates) never expire. They encode data directly and work forever. Dynamic QR codes, which redirect through a tracking service, can expire if the service is discontinued. For permanent use, static QR codes are more reliable.
Can QR codes be customized with colors?
Yes. QR codes work as long as there is sufficient contrast between the foreground and background colors. Dark foreground on light background works best. Avoid low-contrast combinations (yellow on white, light gray on white) as scanners may fail to read them. Test any custom color combination before printing.
How do businesses use QR codes for customer support?
Common uses: linking to a support portal or FAQ page, opening a pre-filled email to the support team, connecting to a WhatsApp or Telegram support chat, or providing WiFi access in office lobbies. QR codes on product packaging can link directly to troubleshooting guides.
