A useful code starts with the right content
A café’s menu, guest WiFi and a contact card need different QR payloads. Choose the matching form and the code updates while you type. A readable payload view lets you inspect what will actually be encoded before you start adjusting colours, gradients or finder patterns.
From a quick handout to print artwork
Designers, marketing teams, shop owners and event organisers can prepare files without installing software. SVG and PDF preserve vector geometry; PNG offers up to 4096 pixels and PDF allows an edge length of 10–500 mm. Uploaded logos remain raster images inside those exports.
Prepare and check your code
- Enter the details for the chosen content type.
- Set module shapes, colours and quiet zone; add a logo if needed.
- Review the readability indicator, then try a real scanner app.
- Choose the file size and name, and download SVG, PNG or PDF.
What stays local and what a link carries
QR content and logo images are processed in the browser without uploads to the app server. Interface fonts are requested from Google Fonts. Only language and theme preferences persist locally; sharing a configuration puts its content into the link. Send links containing contact details or WiFi passwords only to trusted recipients.
