For best scanning results, keep high contrast between the foreground and background colors. Dark codes on light backgrounds work most reliably across all QR readers.
What is the QR Code Generator?
A QR code is a square 2D barcode that encodes text (most often a URL) so a phone camera can read it in a fraction of a second. They first appeared in Toyota's auto plants in 1994 and now sit on menus, posters, business cards, and packaging because every modern phone scans them natively without an app.
How to use the QR Code Generator
- 1
Paste your content
Drop a URL, plain text, or any string into the editor. The QR code regenerates the moment you stop typing.
- 2
Pick size and colors
Choose 256 pixels for screens, 512 for print, or 1024 for posters. Adjust the foreground and background colors if you want it to match a brand.

Check contrast
Dark modules on a light background scan most reliably. If you flip them or pick low-contrast tones, some readers will refuse to lock on.

Frequently Asked Questions
Are the QR codes generated free to use?
Every QR code you generate here is yours, with no watermark and no licensing limits. Use them in print, packaging, ads, business cards, or anywhere else, commercial or personal.
What can I encode in a QR code?
Any short text string works. Common formats include URLs (https://...), plain text, email links (mailto:...), phone numbers (tel:...), and WiFi credentials (WIFI:T:WPA;S:Network;P:Password;;). Most phone scanners recognize these prefixes and offer the right action automatically.
What size should I download my QR code?
Match the output to where it will live. 256 pixels is fine for websites and email signatures, 512 for business cards or A5 flyers, 1024 for posters and any print job over A4. Go bigger if in doubt; scaling up a small image after the fact looks blurry.
Do the QR codes expire?
No. The data is encoded directly into the image's pattern, with no server-side redirect, so the code keeps working as long as whatever it points to (a URL, a wifi network) still exists.
