QR Code Generator

This tool makes a QR code for a web link, any text, a WiFi network or a contact card, and lets you download it as PNG or SVG. The code updates as you type, so you can test it with your phone camera before you print it.

The WiFi and vCard modes save you from learning the formats. For WiFi, enter the network name, password and security type. Phones that scan the code offer to join the network. The vCard mode builds a version 3.0 contact card with name, phone, email and website, which phones can save to contacts. For anything else, such as an email address or a phone number, use Text mode.

Error correction decides how much damage a code can survive. Low recovers about 7% of the code, Medium about 15%, Quartile about 25% and High about 30%. Higher levels add more squares, so the same link makes a denser code. Medium is the default and suits most uses. Pick High for codes that may get scuffed, printed small or partly covered.

For print, download the SVG. It is a vector file, so it stays sharp at any size. PNG is fine for screens, and the size can be set from 128 to 512 pixels. The codes are static: the content is stored in the pattern itself, so they never expire, and nobody tracks the scans. It also means you cannot change a printed code later. Everything is generated in your browser. To check a long link before you encode it, the URL Parser breaks it into its parts. To put the code on a flyer as an image, the Image Resizer can help.
