About Barcode Reader
Barcode Reader scans an image and decodes the 1D/2D barcode in it (CODE128, EAN, UPC, QR, Data Matrix, and more) with the ZXing library, showing the content and its format. This READS a barcode, it does not create one.
The image is processed in the browser and never uploaded.
FAQ
Is my file/data uploaded to a server?
No. Everything is opened and rendered in your browser with JavaScript (the File API). Nothing is uploaded, logged, or stored on our servers — safe for sensitive files.
How is this viewer different from an extractor or parser?
A viewer shows the content as-is (read-only) — you see the file/text the way it is. An extractor pulls raw data (e.g. text from a PDF) into a string, while a parser breaks input into its component structure. A viewer focuses on "see", not "transform" or "pull".
