What types of content can a QR code contain?

QR codes can encode URLs, plain text, Wi-Fi network credentials (SSID and password), vCard contact information, email addresses, phone numbers, SMS messages, and geographic coordinates. This tool automatically detects and labels the content type.

Can I decode a QR code from a screenshot or screenshot taken from another screen?

Yes. You can paste screenshots directly using Ctrl+V (or Cmd+V on Mac). You can also take a screenshot on your phone and upload the image file. As long as the QR code is visible and reasonably sharp in the image, it can be decoded.

What is a QR Code Decoder?

A QR code decoder reads the pattern of black and white squares in a QR code image and extracts the data that was originally encoded. This tool performs that decoding entirely in your browser — no server upload, no account required.

Common uses include checking what a QR code contains before scanning it with your phone, recovering data from a QR code you generated earlier, verifying QR codes on printed materials or digital assets, and reading QR codes found in screenshots or documents.
