QR code generator

Make a QR code from a link, a Wi-Fi login, a contact card and more. Pick a type, fill in the fields, set the colours and error correction, then download the code as an SVG or PNG.

QR code editor format

The editor is form driven, so you rarely need to write anything by hand. Behind the form is a small line based source you can read and edit on the Source tab. The first line is the word qr. Then a type: line, then one line per field, then the render settings: error correction, module size, margin and the two colours.

You write

qr
type: url
url: https://markdown.org
ec: M
cellSize: 4
margin: 4
dark: #000000
light: #ffffff
