Barcode and QR code extension for Chrome

Select a SKU, order number or link on any web page, right-click and choose “Create barcode or QR code”. A small window opens with the code ready to download as PNG or SVG. The same encoder as this site, packed into the extension, so it works offline.

What it does

Right-click menu on selected text: Code 128, QR, EAN-13, UPC-A, Data Matrix and the other types on this site.
Toolbar button: type or paste text without selecting anything.
Check digits and input errors explained, like on the site.
Download PNG (300 or 600 dpi) or SVG.

Permissions

The extension asks for two permissions: the right-click menu (contextMenus) and access to the current tab only when you click it (activeTab). It has no access to the pages you visit, sends no data anywhere and has no analytics.

Availability

The extension is being prepared for the Chrome Web Store. This page will link to it once it is published.
