Encoding and conversion happen entirely inside your browser using JavaScript. Your input is never sent to a server, never logged, and never stored, so there is no database to breach.
The site is served over HTTPS only, with strict transport security enabled and content-type protection on every response to prevent MIME confusion.
If you believe you have found a security issue, email support@qrcodegener.org with the details and steps to reproduce. We acknowledge reports promptly and keep you updated while we investigate.
Most online tools upload your file, process it on a server and hand it back. That design makes the tool provider a target: everything users send sits in a database. This site takes the opposite approach by doing all the work client-side, so there is no user content to steal.,The practical consequence is that a WiFi password, a private URL or a contact record you encode never leaves your device and cannot be read by anyone else, including us.
All traffic is served over HTTPS with HSTS preloading, and every response carries content-type protection to stop MIME confusion attacks. The site sets a strict referrer policy so destination URLs are not leaked to third parties.
