Scan with any phone camera to test it before you share or print it.
How this tool works
A QR code is just a visual way of encoding text using a standardized pattern that any phone camera can decode instantly. This tool builds the correctly-formatted string behind the scenes for whichever content type you choose — a plain URL for links, the special WIFI: format for network credentials so phones prompt "Join network" automatically, mailto: for email, tel: for phone numbers, and SMSTO: for pre-filled text messages — then renders it as a scannable image using a standard open-source encoding library.
The "H" error-correction level built into this tool means the code can still be scanned correctly even if up to about 30% of it is damaged, obscured, or covered by a logo — useful if you're printing it somewhere it might get worn or partially covered.
Frequently asked questions
Is my Wi-Fi password safe to put into this?
The encoding itself happens entirely in your browser — your Wi-Fi details aren't sent to any server as part of generating the code. That said, treat the resulting image itself like a password: anyone who scans it gets network access, so only share or display it where you'd be comfortable sharing the password directly.
Do QR codes expire?
No — a QR code generated this way is a static image encoding fixed text; it doesn't expire and will keep working indefinitely, as long as the destination (like a URL) itself stays valid.
Why won't my phone scan the code sometimes?
Usually it's print size (QR codes need to be reasonably large relative to scanning distance), poor lighting, or a low-quality print. Try increasing the size setting and printing at a larger physical size if you're having scanning issues.
Can I change the colors without breaking it?
Yes, within reason — the foreground needs to stay meaningfully darker than the background for scanners to distinguish the pattern. High-contrast combinations (dark on light, or the reverse) work reliably; very similar shades can cause scanning failures.
What's the difference between this and a "dynamic" QR code?
This tool generates a standard "static" QR code — the destination is baked in permanently. Dynamic QR codes (usually a paid service) redirect through a URL you can update later without reprinting the code, which is useful for things like physical signage where you might want to change the destination over time.
