What is it?

Mini QR is a web app for generating decorative QR codes and reading them back. Users can change colors and styles, add a logo image with adjustable size and margin, and wrap the code in a frame with text. Presets and a randomize button help with quick styling, and saved configurations can be reloaded later.

On the output side, codes can be exported as PNG, JPG, SVG, or ASCII/Unicode text, or copied to the clipboard. A batch mode imports a CSV of data strings and exports a set of QR codes at once. Data templates cover URLs, emails, phone numbers, SMS, WiFi credentials, vCards, locations, calendar events, and EPC/SEPA payment codes.

The scanner reads codes from a camera or uploaded images and recognizes URLs, emails, phone numbers, and WiFi credentials. The interface is available in 30+ languages, supports light and dark modes, and can be installed as a PWA. It is built with Vue 3, TypeScript, and Vite, and includes a Storybook for its component library.
