Fill and verify
The page combines fields into a standard payload. Check the exact encoded content below the code before printing an address or password.

Adjust and scan-test
Keep a dark foreground, light background, and enough quiet zone. Test on a target phone before use, and prefer SVG for print.
§ 02
A static QR code writes content directly into the pattern
This page creates static QR codes. The URL, text, or WiFi configuration is encoded in the matrix, so the result does not depend on our server and has no platform scan limit.
If a URL expires, WiFi password changes, or contact detail moves, an old code cannot update itself. QR content is not encrypted; anyone who can see and scan it may read the payload.

§ 05
Color and quiet zone affect scanning more than decoration
Scanning depends on light-dark contrast. Classic black and white is most reliable; dark blue, green, or gray can work, but avoid pale foregrounds, transparent backgrounds, and similar colors.
The quiet zone is the blank border around the matrix. Removing it, placing text immediately beside the code, or cropping it in design software can prevent a camera from locating the symbol.

Frequently Asked Questions
Q1Is QR content uploaded?
No. Payload assembly, matrix generation, Canvas drawing, and SVG export happen in the current browser page without saved history.
Q2Does the QR code expire or have a scan limit?
A static code itself does not expire and has no scan count, though the URL, account, or WiFi information inside may stop working.
Q3Why will a colored QR code not scan?
Typical causes are low foreground-background contrast, reversed colors, insufficient quiet zone, blurred compression, or very dense modules from a long payload.
Q4Should I download PNG or SVG?
Use PNG for screens and ordinary documents; choose SVG for scaling, layout, or print because its edges stay sharp.
Q5Is a WiFi password safe inside a QR code?
A QR code is not encrypted. Anyone who can see and scan it may read the SSID and password, so display it only where appropriate.
