What can you put in a QR code?
Almost anything that is text: website links, plain messages, Wi-Fi credentials (guests connect by pointing the camera — no typing), and contact cards in vCard format that save straight to the phone book. This generator creates all of these locally in your browser: nothing you type is uploaded anywhere, which also means it works offline after the page loads.
Tips for QR codes that actually scan
Size matters: for print, keep the code at least 2×2 cm and test from the distance people will scan it (a poster across a room needs a much bigger code). Contrast matters more: dark modules on a light background — never invert. And leave the white margin (quiet zone) around the code intact; cropping it is the most common reason codes fail to scan.
Do QR codes expire?
The codes made here are static: the content is encoded directly in the image, so they never expire and depend on no third-party service. The flip side is that the content cannot be changed after printing — if you need to update the destination later, encode a link to a page you control and change the page instead.
Frequently asked questions
Is this QR code generator really free?
Yes — unlimited codes, no sign-up, no watermark. The site is supported by ads.
Do the QR codes expire?
No. They are static codes: the content lives inside the image itself, with no dependency on any service, so they work forever.
Is my data uploaded to a server?
No. The code is generated entirely in your browser — links, passwords and contacts never leave your device.
What size should a printed QR code be?
At least 2×2 cm for close-range scanning. The rule of thumb is scanning distance ÷ 10: a code scanned from 1 meter should be about 10 cm wide.
How does the Wi-Fi QR code work?
It encodes the network name, security type and password in a standard format. Pointing the phone camera at it connects automatically on Android and iOS.
