How to use the QR code generator

  1. Pick a tab for the content type.
  2. Fill in the fields for that type.
  3. Tune size, error-correction level, and foreground/background colors.
  4. Watch the live preview; heed the contrast warning if colors are too similar.
  5. Download PNG or SVG. Nothing is uploaded to a server.

Formula & method

Payloads follow common QR conventions (WIFI:, BEGIN:VCARD, mailto:, tel:).

Error-correction levels L/M/Q/H trade capacity for resilience to damage.

We warn when foreground/background contrast is below WCAG AA (4.5:1).

QR(payload, ecc, colors) → matrix → PNG/SVG

Worked example

URL tab with https://www.numbrixiya.com yields a code that opens that page when scanned.

Wi-Fi tab with WPA encryption embeds SSID and password in a WIFI: payload phones can join.

Frequently asked questions

Is my Wi-Fi password uploaded?

No. Encoding happens entirely in your browser.

Which error-correction level should I pick?

M is a solid default. Use H if the code will be printed small or partially covered.

Why the contrast warning?

Low-contrast codes scan poorly. Navy on white meets AA contrast by default.

Can I download SVG?

Yes. SVG stays sharp at any print size.
