Omni-QR Toolbox

QR code generation, cross-origin image decoding, on-screen region capture, and Wi-Fi code creation in one extension. Omni-QR Toolbox is a QR code tool for people who need to move information between screens quickly. You create or read a QR code from the tab you are already on, and finish the follow-up work of styling, exporting, and keeping a record inside a single popup. Generate a code from the current tab URL, from text you type, or from your Wi-Fi network name and password. The preview updates while you adjust error correction, size, quiet zone, and foreground or background colors, and you can download a PNG or SVG file, or copy the image directly. Decoding works the same way: right-click an image on any page, including images served from another domain; paste an image from the clipboard; drop a file onto the window; or press Alt+Shift+Q to select a region on screen and decode only that area. Everything you generate or decode is kept in a local history you can return to, and the interface follows your system theme or a fixed light or dark choice, in English or Traditional Chinese. The extension works entirely offline, collects no data, contacts no server, and asks only for the permissions it actually uses.
