How to use Barcode Scanner
Decode barcodes from uploaded images in your browser — supports Code 128, EAN-13, UPC-A, Code 39, QR codes, and DataMatrix. No camera access needed: upload a photo, screenshot, or image file and the decoder instantly returns the barcode value. Useful for verifying labels, checking product codes, and extracting inventory data from images.
- Upload a JPG, PNG, or WebP image containing the barcode.
- The scanner detects the barcode type and decodes the value automatically.
- Review the decoded number or text displayed below the image.
- Copy the value to your clipboard for use in inventory or lookup systems.
- For multiple barcodes in one image, all detected codes are listed.
Your data never leaves your device — 100% private processing.
Supported barcode formats
The scanner supports all major 1D and 2D barcode symbologies: Code 128, Code 39, Code 93, EAN-13, EAN-8, UPC-A, UPC-E, ITF, Codabar (for libraries and blood banks), QR code, Data Matrix, Aztec, and PDF417 (used on driver's licenses and boarding passes). If decoding fails, ensure the barcode is not obscured by glare or shadow, is sufficiently in focus, and that the entire barcode including quiet zones is visible in the image.

|---|---|---|
| Code 128 | 1D | Shipping, logistics, ID cards |

Common issues and troubleshooting
Barcode scanning fails most often due to: low image resolution (barcode should be at least 100 pixels wide), heavy JPEG compression artifacts near the barcode, glare or shadows obscuring bars, or significant skew (more than 45°). For printed barcodes photographed with a phone, take the photo at a 90° angle to minimize perspective distortion. Increase image contrast using your phone's camera settings before uploading if the barcode is faded or printed on a colored background.
