    How to use the Barcode Scanner

    1. Choose a photo, drop it on the box, or paste a screenshot with Ctrl+V (Cmd+V on a Mac). On a phone or laptop you can press Scan with camera.
    2. Read the result: the barcode type, the decoded value, and notes such as whether the check digit is right.
    3. Press Copy to take the value into a spreadsheet, a stock system, or a search.

    How it works

    • Where the browser ships the BarcodeDetector API, as Chrome does on Android and macOS, the scanner uses it. Everywhere else it loads the ZXing decoder (zxing-cpp compiled to WebAssembly, about 1 MB) on the first scan. Both can return several barcodes from one image.
    • ZXing also tries the image turned on its side and with light and dark swapped, so sideways and inverted barcodes are found too.
    • Photos are scaled to 1,600 pixels on the long side and camera frames to 1,000 before decoding.
    • For EAN-13, EAN-8, UPC-A, and UPC-E the GS1 check digit is worked out again and compared. An EAN-13 that starts with 978 or 979 is marked as a book number, and a UPC-E code is shown with its full UPC-A form.

    Examples

    • A photo of a book's back cover returns EAN-13 9780306406157, marked as an ISBN.
    • The UPC-E code 04252614 from a small can is shown with its UPC-A form 042100005264.
    • A test print of a label sheet: one photo of three labels returns all three values, so you can compare them with your list before you print the whole run.

    Limitations

    • Blurry, very small, or cut-off barcodes may not decode. The white margin on both sides of the bars has to be in the picture.
    • MSI and Pharmacode barcodes are not read.
    • The scanner reads the number and the type. It does not look up products, prices, or who owns the number.
    • Camera scanning needs HTTPS and your permission.

    Make barcodes in bulk and print labels

    Turn a spreadsheet column into barcodes or QR codes, print them on A4 or Letter label sheets, and scan a test page before you print the rest.

    Frequently asked questions

    How do I scan a barcode from a picture?

    Upload the photo or paste a screenshot. The decoded value and the barcode type appear under the box, one entry for each barcode found.

    Can I scan a barcode with my laptop camera?

    Yes. Press Scan with camera and allow access. Hold the barcode level and close enough that it fills a good part of the frame.

    Does the scanner tell me what product it is?

    No. It reads the number and the format. A product lookup needs the database of the company that owns the number.

    Are my images uploaded?

    No. Images and camera video are decoded in your browser.
