QR Code Generator | Create Custom QR Codes

How do I create a QR code for a website link?

Select URL as the content type, paste your full web address including https://, and the QR code generates live in the preview. Download the image as a PNG to share or print. The QR code links anyone with a phone camera directly to that URL when scanned.

Is the QR code generator free and does it send data to a server?

The tool is free and generates QR codes entirely in your browser using a JavaScript library loaded from a CDN. Your input text and the resulting QR image are never sent to or stored on any external server. You can create QR codes for sensitive internal URLs without exposing them to third-party services.

How do I make a QR code for WiFi so guests can connect without a password?

Select WiFi Network as the content type, enter your network name (SSID), password, and security type (WPA/WPA2 for most home routers). The QR code encodes all credentials in the standard WiFi format. Guests scan it with their phone camera and connect automatically without typing the password.

What size should my QR code be for printing?

For most printed materials, 256 x 256 pixels (the default) is sufficient for business cards or flyers at normal viewing distance. Choose 512 x 512 for posters or signage viewed from farther away. The error correction level also matters: use Medium (15%) for standard uses or High (30%) if the QR code may be partially obscured.

What is error correction in a QR code?

Error correction allows a QR code to be scanned correctly even if part of it is damaged, dirty, or covered by a logo. Low (7%) is fine for clean digital displays. Medium (15%) suits printed materials. High (30%) is best if you plan to overlay a logo on the QR code, as it can recover up to 30% of lost data.
