How to create a QR code for free
A QR code should match what you are asking people to do. The fastest path is: pick the type, use clean data, test one scan, then export for screen or print.
1. Pick the right QR type
- URL — any https link (menus, landing pages, PDFs hosted online).
- WiFi — guests join without typing the password.
- WhatsApp — opens a chat with your number (great for shops).
- vCard — saves contact details after scan.
- Location — opens Maps from an address or place name.
Kodotools splits some of these into fast pages (for example WiFi and WhatsApp) and keeps everything else in the full generator.
2. Enter data that survives a scan
Use full https:// links. For phone numbers, include your country code. For WiFi, double-check SSID and security type (WPA vs open).
If your QR will be printed small, avoid stuffing enormous amounts of text into a single code — density makes scanning harder.
3. Customise and export
High contrast between “modules” (dark squares) and background scans best. Kodotools lets you download PNG and JPG for screens and photos, plus SVG for sharp print.
If you add a logo, keep it small and test on more than one phone — see our design tips.
Privacy
On Kodotools, QR generation runs in your browser. That matters when your payload is a WiFi password, personal phone number, or internal form link.
