QR Code Generator

Generate custom QR codes for free. Instant, secure, and works offline. Perfect for business cards, marketing materials, and sharing links.

Input

Contrast ratio: 21.00:1 — suitable contrast for a readable QR code.

Preview

Enter text or URL to generate QR code

Practical guide

Create a QR code for a printed link

Use a complete HTTPS address when the code should open a website. Plain text is also allowed, but a phone may display that text instead of offering to open a browser.

Worked example

Enter https://pulsasuite.com/guides, generate a black-on-white code, and scan the preview with a phone. Download PNG for a raster image or SVG when a print designer needs a scalable vector. Keep the white border when placing it in a document.

Check the result

Test the exported file, not only the preview. Scan the final printed size on more than one device, and verify the destination spelling. Shorter content generally creates a less dense symbol that is easier to print small.

Limitations to know

The contrast warning is a useful design check, not a guarantee that a QR code will scan. Printing, glare, cropping, quiet-zone size, and camera quality also matter. The code is static: changing its destination requires a new code unless the original address redirects.
