Does the logo break the QR?

With H correction, a ~20% centre logo usually works. Too large or too busy can fail. Check with a phone camera.

Paste the payload (WIFI:T:WPA;S:…;; or BEGIN:VCARD). The tool encodes the string as-is.

Is anything sent to a server?

No. The QR is drawn in a canvas; the PNG downloads from the tab.

(01) — TOOLS

URL, text, colours, logo. Finder patterns stay square so it still scans. Nothing is sent.

(02) — METHOD

01 — Payload

Text or URL, up to 800 characters. Error correction M, or H when a logo covers the centre.

02 — Style

Module and background colours. Data dots can be rounded; the three eyes stay sharp.

03 — Logo

PNG or JPEG, local. A backing disc keeps modules readable. Scan it before you print.
