What barcode types are supported?

This scanner reads QR codes and common 1D barcodes including Code 128, EAN-13, and UPC-A from uploaded images.

Can it read 2D codes like Data Matrix and PDF417?

Yes. Alongside 1D symbologies it decodes QR, Data Matrix, Aztec and PDF417 — the stacked format on driver licenses and boarding passes — so you can extract data from ID documents and travel passes from a saved image.

Why won't my barcode photo decode?

The usual culprits are low resolution (aim for the barcode at least 100 px wide), JPEG compression artifacts, glare or shadow across the bars, or skew beyond about 45°. Shoot straight on at 90°, with even lighting, and include the quiet zones.

Do I need a camera to use it?

No. It decodes from any uploaded photo, screenshot or image file, so a picture of a label is enough. That is useful for checking codes on packaging or documents you have already photographed.

Can it scan a barcode on a colored background?

It can if there is enough contrast between bars and background. Faded or low-contrast labels decode more reliably if you boost contrast in your phone camera or an editor before uploading.

How do I read a barcode from a boarding pass?

Save or screenshot the pass, then upload it — the PDF417 barcode decodes to the underlying booking data. Everything is processed in your browser, which matters since boarding passes contain personal travel details.

Can it detect multiple barcodes in one image?

Yes. If a single image contains several barcodes, each is detected and its decoded value listed, letting you process a sheet of labels or a multi-code document in one upload.

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.

Barcode symbology reference

Code 128	1D	Shipping, logistics, ID cards
EAN-13	1D	Retail products, books (ISBN)
UPC-A	1D	North American grocery/retail
Code 39	1D	Automotive, healthcare, military
ITF-14	1D	Outer shipping cartons (GS1)
Codabar	1D	Blood banks, libraries, FedEx
QR Code	2D	Mobile, marketing, payments
DataMatrix	2D	Electronics, pharma, aerospace
PDF417	2D	Driver's licenses, boarding passes

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.
