Why is my barcode not being detected?

Barcode detection depends on image quality. For best results, ensure the barcode is clearly visible, well-lit, and not blurry.

Tips for better scanning:

Upload a higher resolution image
Hold the camera closer to the barcode
Ensure good lighting conditions
Avoid blurry or out-of-focus images
Make sure the barcode is not damaged or obscured

Note: Damaged or partially obscured barcodes may not be readable.

Clicking it opens a Google search with the barcode number, helping you find:

Yes. Your scan history is saved in your browser's local storage and will persist even if you close the browser. You can clear all history at any time using the Clear All button in the history panel.

Can I scan multiple barcodes from one image?

Currently, the tool detects one barcode per image. If your image contains multiple barcodes, it will decode the most prominent one.

For multiple barcodes:

Scan each one separately by cropping the image
Use the camera to scan them one at a time
Enable continuous scanning mode to scan multiple barcodes quickly
