QR Studio – QR Code Generator & Scanner

Most QR tools hide the good parts behind a paywall, mark them “coming soon,” or quietly send your data to a server. QR Studio does the opposite: every professional feature is built in, free, and runs entirely on your device.

Why install it QR Studio generates and scans QR codes 100% locally. No network requests, no analytics, no account, no remote API — your data never leaves your browser. It works fully offline.

What you can do
