QRCode Scanner

Scan and decode QR Code. Internet is not required.

QRCode Scanner is a privacy-focused Chrome extension designed to quickly scan and decode QR codes directly from webpages without requiring internet access. It offers offline decoding to ensure your data stays private and never tracks your usage.

Key features include support for both image-based and non-image QR codes (like text selections in PDFs), manual image adjustments such as clipping, contrast enhancement (OTSU), and color inversion. The extension also provides an option to auto-close the result window for a seamless user experience. Fully open source, QRCode Scanner ensures transparency and reliability.

It effectively scans QR codes from web images without unnecessary features. However, some users face issues with the extension being grayed out or needing manual enabling.
