How to use QR Code & Barcode Scanner
Choose Camera and press Start camera, then point it at a code; results appear instantly with a beep. Or choose Image or PDF to drop files, paste a screenshot with Ctrl+V or try the example. Review each result, copy it, open links only after checking the address, and download all results as CSV, TXT or JSON.
How it works
Every frame and file is decoded in your browser by a self-hosted, integrity-checked WebAssembly build of the open-source ZXing-C++ reader; nothing is uploaded. Several codes per image are detected and outlined. Content is interpreted: links with phishing warnings (http, punycode, IP hosts, user names before @, shorteners), Wi-Fi credentials, vCard/MeCard contacts (.vcf download), calendar events (.ics), email, SMS, phone, map coordinates, 2FA otpauth secrets (masked), crypto payment URIs, EPC SEPA and Swiss QR-bill payments, EAN/UPC check digits with the issuing GS1 prefix (not the country of manufacture), ISBN-10/13, ISSN and GS1 application identifiers such as GTIN, batch, serial and expiry dates, including GS1 Digital Link URLs. Product names and prices are not looked up, because that would require sending codes to an external database.
Example
Try the built-in example: one image containing a Wi-Fi QR code, an EAN-13 product barcode, a GS1 Data Matrix with expiry date and batch, and a link QR code. All four are found and explained.
