Frequently Asked Questions

No. The QR code itself encodes your data directly (a URL, text, WiFi details, etc.) - it doesn't expire and will work forever as long as the underlying information (like a website URL) remains valid. There's no tracking, account, or subscription involved; once downloaded, the QR code image is yours to use indefinitely.
A QR code can hold up to about 4,296 alphanumeric characters or 7,089 numeric digits, though practical limits are much lower for reliable scanning - shorter content (like a URL) produces a simpler, easier-to-scan code, while very long text creates a denser, harder-to-scan pattern. For long content, consider linking to a webpage instead of embedding all the text directly.
Yes - select the WiFi mode, enter your network name (SSID), password, and security type. When scanned with a phone camera, most modern phones will prompt to join the network automatically without the guest needing to type the password manually.
Yes, as long as there's strong contrast between the foreground and background colors - dark foreground on a light background (or vice versa) scans reliably. Avoid similar or low-contrast color combinations (like light gray on white), as these can cause scanning failures on some devices.

QR Code Generator - Create Free QR Codes for Any Purpose

QR (Quick Response) codes have become a standard way to bridge print and digital - restaurant menus, business cards, event flyers, and product packaging all commonly use them to link straight to a webpage, WiFi network, or contact detail with a single phone camera scan. This generator creates QR codes for four common needs: website links, plain text, WiFi network sharing, and email addresses.

No sign-up, no expiration: The QR code encodes your data directly and works forever, as long as the underlying link or information stays valid.

Choosing the Right QR Code Type

  • Website / URL: The most common use - link directly to a webpage, menu, portfolio, or social profile.
  • Plain Text: Good for sharing a short message, address, or code without needing a webpage.
  • WiFi: Lets guests join your network by scanning, without typing a password - great for offices, cafes, and Airbnb guests.
  • Email: Opens the scanner's default email app with the address (and subject) pre-filled, useful on business cards and contact pages.

Tips for Printable QR Codes

For codes that will be printed and scanned from a distance (posters, signage), use the larger size option and keep strong color contrast - a dark foreground on a light background scans most reliably across different lighting conditions and camera qualities. Test any QR code with a couple of different phones before printing in bulk, since not all scanning apps behave identically.

How this calculator works, and where the numbers come from

The QR Code Generator applies the standard formula for this calculation to the values you enter and updates the result as you type. The calculation itself happens in your browser, and the page explains the method so you can check any result by hand.

Please note: Results are provided for general information and are calculated from the values you enter.
