Is It Safe to Scan QR Codes Online? Privacy Guide

February 15, 2026 Security Team

The Hidden Danger of Online Scanners

When you use an online tool, you need to know where your data goes.

Many 'free' scanners work by uploading your image to a remote server. The server reads the code and sends back the result.

The Risk: If you scan a private WiFi code, a personal ticket, or a crypto key, that image is now on someone else's server. They could save it, view it, or hack it.

The Safe Alternative: Client-Side Scanning

Client-side scanning is different. It happens 100% inside your web browser.

The website sends the scanning code (JavaScript) to your device. Your device does the work. The image never leaves your phone or computer.

How We Protect You

Our scanner is built on this secure technology.

  • No Uploads: We never see your images.
  • No Logs: We do not track what you scan.
  • No Cookies: We do not use tracking cookies for ads.

Always check the 'Privacy Policy' of any tool before scanning sensitive information. If they don't explicitly say 'Client-Side', assume they are uploading your data.
