Make a QR code for a link, plain text, a Wi-Fi network, a contact card, an email, a phone number or a text message. Pick the size, colours and error correction, then download PNG or SVG.
Everything is drawn in your browser. Settings are remembered on this device; Share setup copies a link that rebuilds them.
Turns what you type into a QR code the moment you type it, using the standard encodings phones expect: a plain URL for links, WIFI: for network details, a vCard for contacts, mailto:, tel: and sms: for the rest. The code is drawn on a canvas at the size you choose and can be saved as a PNG or as an SVG, which scales to a poster without going soft. Error correction, quiet zone and colours are all adjustable, and the page warns you when a colour choice is likely to fail a scan.
A Wi-Fi code for a guest network: SSID Cafe Guest, WPA2, password 14 characters. The payload is 47 characters, which at error correction M fits in a version 3 code, 29 modules across. Exported at 512 px it prints crisply at 4 cm; for an A4 table card export the SVG or choose 2048 px. A vCard with name, phone, email and company is around 120 characters and needs a denser version 7 code, so keep the print size above 3 cm.
Use it for menus, posters, business cards, packaging, event tickets and Wi-Fi sharing. Keep the content short: the longer the text, the denser the code and the harder it scans from a distance. If you need the code inside a flyer, download the SVG and place it, or use Add Text to put a caption under the PNG. To turn several codes into one printable sheet, Image to PDF does it. Do not use it for anything that must not change later; a QR code is fixed once printed, so link to a page you control instead.
Size is the pixel width of the PNG; 512 is fine for screens, 1024 or more for print. Quiet zone is the blank border in modules; readers need at least 2, the specification says 4. Error correction L, M, Q and H let the code survive 7%, 15%, 25% or 30% damage or covering, at the cost of a denser pattern; M is the usual choice, H if you plan to put a logo on top. Colours should stay dark on light with at least 4:1 contrast; the page tells you when they do not. The Wi-Fi password and contact details are never put into share links.
Will the code still work if I change the link later? No. The code contains the text itself. Point it at a page you control and change that page instead.
PNG or SVG? PNG for screens, documents and quick prints. SVG for anything that will be scaled, like signage, since it stays sharp at any size.
Can I use a coloured or inverted code? Coloured, yes, as long as the modules are much darker than the background. Inverted (light on dark) codes fail on many phones, and the tool warns you.
Is what I type sent to a server? No. The code is generated by a library running in your browser. Wi-Fi passwords and contact details stay on your device.
