Error correction is forced to H and the code is enlarged to at least version 7 so the picture shows through. Every change is decoded on your device before download unlocks.

Halftone codes download as PNG or SVG. Bigger dots and a faded picture scan more reliably in print.

Make it editable and trackable

Creates a short link in a free SignUpCity account and brings you back here with it. StoneQR stores nothing. SignUpCity's links carry a published no-deactivation policy.

Free means free, and static means forever

Most "free" QR generators hand you a code that points at their own server, then stop forwarding it when a trial ends. The codes on this page contain your content directly, so there is nothing to switch off. There is no account, no email, and nothing you type leaves your device. Here is how that works.

Made for printing

Choose a print width and the panel tells you the module size, how far away the code can be read from, and when the content is too long for the space. Download SVG, PDF (with 100% K black), EPS, or PNG at 300 dpi with the resolution recorded in the file. The print-size calculator is also available on its own page, and a one-page test sheet prints the code at four sizes so you can scan before ordering signage.

Every content type a phone understands

Links, WiFi networks, contact cards, email, SMS, phone numbers, map pins, and calendar events, formatted the way phone cameras expect. Add a logo, choose colours with a contrast check, or add a frame with a call to action.
