About QR Codes

A QR code (Quick Response code) is a 2D barcode that encodes text, URLs, or other data into a scannable square pattern. Any smartphone camera can decode one instantly — making QR codes the fastest way to share a link with someone in the same room.

How it works

This tool uses the qrcode library to generate the QR matrix in your browser. The error correction level is set to M (15%) — meaning up to 15% of the code can be damaged or obscured and it will still scan correctly. Higher sizes (512px) are best for print; 256px is ideal for screens.

Frequently Asked Questions

Is the QR Code Generator free?

Yes — completely free. No account, no watermark, and no scan limits.

Is my data sent to a server?

No. QR codes are generated entirely in your browser using the qrcode library. The URL or text you enter is encoded directly into the image and never transmitted anywhere.

Do I need an account?

No account, no login, and no signup required.

Do these QR codes expire?

No. Static QR codes encode the destination directly into the pattern — when someone scans it, their phone reads the URL from the code itself. There is no third-party server involved, so there is nothing to expire or go offline.

What size should I use for printing?

Use 512px and print at a minimum physical size of 1×1 inch. Larger physical codes scan more reliably from a distance and on low-contrast backgrounds. For screens only, 256px is sufficient.

Why won't my QR code scan reliably?

The most common causes: low contrast between the code and background, the quiet zone (white border) being cropped in your design, too much data encoded in a long URL, or low print resolution. Test on the actual material before printing a full run.
