Frequently Asked Questions
How do I read a barcode online?
Upload an image containing a barcode to a browser-based barcode reader, or grant camera access for live scanning. The tool uses the BarcodeDetector API (Chrome/Edge) or ZXing WASM (Firefox/Safari) to decode the barcode and display its content — no server upload needed.
What barcode formats can I scan in the browser?
Modern browser-based readers support Code 128, Code 39, EAN-13, EAN-8, UPC-A, UPC-E, ITF, and Codabar for 1D barcodes. For 2D formats: QR Code, Data Matrix, PDF417, Aztec, and MaxiCode. The BarcodeDetector API determines the supported list per browser.
How do I scan a barcode from a photo?
Drag the photo file onto the barcode reader or click to browse and select it. The tool draws the image to a Canvas, passes it to the BarcodeDetector API or ZXing decoder, and returns the decoded value with the barcode type and bounding box coordinates.
What is EAN-13?
EAN-13 (European Article Number) is a 13-digit barcode standard used on retail products worldwide outside North America. The first 2–3 digits identify the country code of the issuing GS1 organization, followed by a company prefix, item reference, and a check digit.
How do I use my camera as a barcode scanner?
Click 'Use Camera' in the barcode reader tool, grant camera permissions when the browser asks, and point your camera at a barcode. The tool samples frames from the video stream using the MediaDevices API and attempts to decode each frame in real time.
