How to Make a QR Code (Free, in Seconds)

Making a QR code takes about ten seconds: choose what the code should do, enter the data, and generate. This guide covers the four most common uses and the size rules that keep codes scannable.

QR for a website link

  1. Open the QR Code generator.
  2. Paste your URL on the first line - for example https://yourmenu.example.com.
  3. Click Generate. The QR encodes that exact link.
  4. Save the image or print it. Anyone who scans opens the page.

QR for Wi-Fi login

Encode a WIFI string so guests join your network by scanning: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;. Phone cameras recognize this format and offer a one-tap connect - no password typing.

QR for a business card (vCard)

Encode a MECARD string to save a full contact: MECARD:N:Last,First;ORG:Company;TEL:+14155550123;EMAIL:[email protected];URL:https://you.example;. Scanning saves the card straight to the phone's contacts.

Size and printing rules

  1. Print at least 15-20mm wide for phone scanning.
  2. Keep a clear white quiet zone around all four sides.
  3. Dark modules on a light background - never on busy artwork.
  4. Do not stretch the image; a distorted QR will not scan.

Frequently Asked Questions

Are QR codes free to generate?
Yes - QR is an open standard. This generator creates codes locally in your browser with no watermark and no sign-up.
Do QR codes expire?
Static QR codes (which store data directly) never expire. Only paid 'dynamic' services that redirect via their own URL can stop working.
Why does my QR code not scan?
Most often: printed too small, no quiet zone, low contrast, or the image was stretched. Re-print at 15-20mm with white space around it.
Can I make many QR codes at once?
Yes - the QR Code generator accepts a list, one data item per line, and outputs each as its own code.
