How to Create a QR Code for Free
Creating a QR code takes under two minutes with QRGen. No sign-up required for static codes. This guide walks you through every step — from choosing a type to downloading the finished file.
Choose your QR code type
Decide what your QR code should do. Should it open a website URL? Share contact details (vCard)? Connect to WiFi? Start a WhatsApp conversation? QRGen supports 12+ types — pick the one that matches your use case.
Fill in your content
Enter the information your QR code will encode. For a URL QR code, just paste the link. For email, enter the address, subject, and body. For WiFi, enter the network name and password. The QR code preview updates in real time.
Customize the design
Change the QR code color, dot shape, corner style, and add a logo or icon. You can also add a decorative frame with a call-to-action label like 'Scan me' or 'Free WiFi'. A well-designed QR code gets scanned more often.
Download in the right format
For print — business cards, posters, packaging — always download as SVG (vector). SVG scales to any size without losing quality. For digital use — emails, websites, presentations — PNG at 1000×1000px is ideal.
Pro Tips for Better QR Codes
- Always test your QR code before printing by scanning it with two different phones.
- Use a high error correction level (H) if you're adding a logo — it lets the QR code recover even when part of it is covered.
- Keep quiet zones clear — a white margin of at least 4 modules around the QR code prevents scan failures.
- Minimum print size is 2cm × 2cm. For posters, aim for at least 4cm × 4cm.
- Dark QR code on a light background always scans better than the reverse.
