Frequently Asked Questions

What code types can this reader decode?

The reader decodes QR codes (all versions), as well as common linear barcodes including CODE128, EAN-13, EAN-8, UPC-A, UPC-E, CODE39, and ITF. The underlying library uses ZXing, one of the most widely adopted barcode processing engines.

Does my image get uploaded to a server?

No. Decoding happens entirely in your browser using the ZXing JavaScript library. Your image data never leaves your device.

What image formats are supported for upload?

You can upload PNG, JPEG, GIF, WebP, and most other common image formats. The image is decoded client-side, so file size constraints are determined by your browser memory rather than a server limit.

Why does the scanner fail to read my QR code?

Common causes include a blurry or low-resolution image, insufficient contrast between the code and background, a partially damaged or obscured code, or very small codes photographed from too far away. Try a clearer, closer, or better-lit image.

Can I scan a barcode on a product label?

Yes. Upload or photograph the barcode on the label. EAN-13, UPC-A, and CODE128 are all supported: the most common formats used on retail and shipping labels.

Does the camera mode work on mobile?

Yes. On mobile browsers the camera permission prompt will give you the option to use the front or rear camera. Rear camera works best for scanning physical codes.

Can I decode a QR code from a screenshot?

Yes. Take a screenshot of the QR code, save it, and upload it to the tool. This is useful for decoding QR codes found in emails, documents, or websites.

What data can a QR code contain?

QR codes can encode plain text, URLs, Wi-Fi credentials (SSID and password), contact cards (vCard), email addresses, phone numbers, geo-coordinates, and more. The decoded value reveals what was encoded.

Can I use this to check if a QR code links to a safe URL?

The tool displays the decoded URL, allowing you to inspect it before visiting. Always verify the domain name carefully before following a decoded link.

Is there a limit to how many codes I can scan?

No. You can scan an unlimited number of codes: there are no usage limits, no accounts, and no rate limiting.
