QR Code puts a scannable code on your site that is generated in the visitor's own browser, so nothing you encode is sent to a server. Encode a link, the current page, text, a contact card, WiFi login, an email, a phone number, an SMS or a calendar event. Pick square, rounded or dot styling, your own colors, an error-correction level and a logo for the middle. Add campaign tags (utm_source, utm_medium, utm_campaign) to links so visits show up in your own site analytics. Visitors can download the code as a high-resolution PNG or as an SVG for print. The dashboard warns you when colors are too close together to scan reliably. To be upfront: these are static codes. The app does not count scans and cannot change a code after it is printed, so test the live code with your phone before you print. No account, no scan limits, no watermark.
