QR Code Generator

How to use

1. Pick a content type - URL, text, email, phone, SMS, WiFi, vCard or geo location.
2. Fill in the fields, then customize colors and optionally upload a logo.
3. Choose a size and error correction level, then download as PNG or SVG.

Use cases

1. Use case: Event check-in Generate a QR code with a check-in URL, add your event logo, and print it on posters and tickets.

2. Use case: Share Wi-Fi with guests Encode your network name and password as a Wi-Fi QR code so visitors can join without typing the password.

Practical tips

Error correction level matters: higher levels survive damage and logo overlays but increase code density, so choose based on where the code will live. Contrast and quiet zone make the difference between a code that scans instantly and one that doesn't — dark modules on a light background with clear margin. Payloads are flexible: URLs are the common case, but Wi-Fi credentials and contact cards scan into phone settings directly. Always test-scan before printing a batch. Like every tool on this site, the Qr Code Generator runs entirely in your browser: the data you enter never leaves your device, nothing is uploaded to a server, and the tool keeps working if your connection drops.

Common mistakes

QR failures happen at print time, not at generation time:

• Printing a batch without a test scan — always scan the actual printed size on the actual material first.
• Insufficient contrast or quiet zone: dark modules on a light background with clear margin scan instantly; inverted or cramped codes often fail.
• Choosing a low error-correction level for codes that will live outdoors or sit under a logo overlay.
• Encoding more data than needed — denser codes are harder to scan, especially at small print sizes.
