Scan or upload QR codes to extract the encoded data.
A QR Code Scanner lets you decode any QR code image by uploading a screenshot or photo directly to your browser—no app install needed. Whether you've received a QR code in an email, document, or poster, this tool instantly extracts the hidden URL, text, or contact details.
A QR code is a two-dimensional barcode made up of black and white squares that encodes data (usually a URL, text, or contact information). A QR scanner is software that reads these patterns and decodes the information inside them. Unlike a physical barcode scanner, a QR code scanner works on any device with a camera or image file, making it fast and accessible online.
The scanner analyzes the uploaded image or photograph, identifies the QR code pattern (including its three corner position markers), and uses mathematical algorithms to decode the position and data layers. It then extracts the encoded information and displays it—whether that's a web link to click, plain text to read, or structured data like contact details or WiFi credentials.
| Input | Result | Notes |
|---|---|---|
| A QR code image from a restaurant menu | Decodes to the URL: https://example.com/menu-pdf | Useful for viewing full menus on your phone without typing the link manually |
| A QR code from a product label or packaging | Decodes to a product landing page or verification link | Helps verify authenticity or access warranty information instantly |
| A QR code image from a WiFi sign or event poster | Decodes to network credentials or event details | Quickly join networks or access event information without manual entry |
Yes—upload or paste the image file directly into the scanner. Most modern phones also have built-in QR scanning in the camera app, but this online tool works if you already have the photo saved.
The decoding itself is safe, but always inspect the decoded URL before clicking it. Malicious QR codes can link to phishing sites or malware. If the destination looks suspicious, do not open it.
The image may be too blurry, too small, or damaged. Try uploading a clearer, higher-resolution photo, or ensure the QR code's corner markers are fully visible and unobstructed.
QR codes commonly encode URLs, plain text, contact information (vCard format), WiFi login credentials, calendar events, email addresses, and phone numbers—up to 4,296 characters depending on the version.
You need internet to use this online scanner, but once decoded, you can copy the result and use it offline. Alternatively, if your device has a built-in QR camera, that works without internet.
QR codes include error correction (up to 30%), so slightly damaged codes may still decode. Heavily faded or torn codes are less likely to succeed—a high-contrast, clean image gives the best results.
