What Barcode Reader Does
Barcode Reader extracts the value stored in common one-dimensional and two-dimensional codes from a local image or from your camera. It supports QR Code, Data Matrix, PDF417, Aztec, Code 128, Code 39, EAN, UPC, ITF, Codabar, and other formats handled by the in-browser scanner.
When to Use It
Use it when you have a product label, shipment label, ticket, inventory tag, packaging photo, screenshot, or document image and need to inspect the exact encoded value before acting on it. The decoded content stays visible so you can copy it, open supported links, or compare it with the source image.
Privacy and Camera Behavior
Images are decoded locally in the browser and are not uploaded. Camera scanning uses the browser’s camera permission prompt, then stops automatically after a code is decoded. You can also stop the camera manually at any time.
Tips for Better Scans
- Use a clear image where the whole code is visible and not stretched.
- Keep labels flat, sharp, and well lit when scanning with the camera.
- For long one-dimensional barcodes, leave quiet space on both ends of the bars.
- If a photo does not scan, crop around the code or try a higher-resolution image.
