How to Use Barcode Decoder
Decode barcodes and QR codes from an image or your camera in one step. Everything runs in your browser, so your images stay private and are never uploaded.
- Upload a photo containing the code, or switch to the camera and point it at the barcode or QR code.
- The decoder detects supported formats automatically, including EAN-13, UPC-A, Code 128, Code 39 and QR.
- Wait for the decoded content to appear — no extra clicks are needed.
- Copy the result and use it wherever you need the encoded data.
- If nothing is detected, try a sharper image, better lighting or move the camera closer.
A code that fills a good part of the frame with even, glare-free lighting is detected far more reliably.
