What is a QR Code & Barcode Reader?
A QR code and barcode reader is a tool that decodes the information stored in visual codes. QR codes (Quick Response codes) are two-dimensional barcodes that can store text, URLs, contact information, and more. Traditional barcodes are one-dimensional and typically store product numbers used in retail.
Our online scanner works directly in your browser—no app download required. Simply upload an image containing a QR code or barcode, and the tool will instantly decode the content. This is especially useful for scanning codes from screenshots, emails, or images where you can't use your phone's camera.
Unlike phone-based scanners that may automatically redirect you to URLs, our tool shows you the decoded content first, letting you review it before taking action. This provides an extra layer of security against malicious QR codes.

Frequently Asked Questions
What barcode formats are supported?
Our scanner supports QR Codes, EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, Code 93, Codabar, ITF, PDF417, Aztec, and Data Matrix. Most common retail barcodes and QR codes are fully supported.
Is my image uploaded to a server?
No. All scanning and decoding happens directly in your web browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
Why can't the scanner read my QR code?
Common reasons include: (1) Low image quality or blur. (2) QR code is too small or cropped. (3) Poor lighting or shadows. (4) Damaged or partially covered code. Try using a clearer image or cropping closer to the code.
Can I scan screenshots?
Yes! Screenshots work perfectly. You can scan QR codes from social media posts, emails, websites, or any screenshot containing a code. Just upload the image or drag and drop it onto the scanner.
What happens when I scan a URL?
When a QR code contains a URL, the scanner automatically detects it and provides an 'Open URL' button. You can review the URL before opening it, which is safer than scanning with a phone camera that might redirect automatically.
Does it work on mobile devices?
Yes, the scanner is fully responsive and works on smartphones and tablets. You can upload photos directly from your camera roll or take a new photo to scan.
What is the scan history feature?
The scanner saves your last 10 scans in your browser's local storage. You can view previous results, restore them, or clear the history. This is useful for comparing multiple codes or referencing past scans.
Can I scan multiple codes in one image?
Currently, the scanner detects the first/most prominent code in the image. For images with multiple codes, try cropping to isolate each code, then scan them individually.
What is the difference between QR codes and barcodes?
Traditional barcodes (like UPC and EAN) are one-dimensional and store limited numeric data, typically 8-13 digits. QR codes are two-dimensional and can store much more data including text, URLs, contact info, and more—up to 4,296 alphanumeric characters.
Is this tool free to use?
Yes, completely free with no limits. There are no watermarks, no registration required, and no usage caps. Use it as much as you need for personal or commercial purposes.
