URL QR code

Build a static payload from a plain https:// URL and validate export parameters; no redirect wrapper, no tracking.

Inputs and parameters

url — URL (http/https only)
size — Size (128–2048, even px)
margin — Quiet zone (≥4 modules)
errorCorrectionLevel — Error correction
format — Export format plan
foreground — Foreground (default #000000)
background — Background (default #FFFFFF)

Real example

url=https://ailounge.top/guides/ · size=512 · margin=4 · level=M · format=png
→ payload=https://ailounge.top/guides/ (21 bytes) → plan qr-url-<timestamp>.png: 512×512, 4-module quiet zone, ECC M, black/white 21:1; no image bytes this round.

Limits and failure handling

Validates and outputs the payload + export plan only; no PNG/SVG bytes. No encoder library bundled; real scanners and rescan identity untested.

FAQ

Can I encode javascript: or data:?

No. Both construction and opening allow only http/https and refuse credentials/control characters.

Any dynamic redirect or scan tracking?

No. The payload is the URL itself; the QR is static and this site records no visits.
