How to Use Codex - QR Reader & Generator

Point your camera, drop an image, or type a URL — Codex reads and builds QR codes without friction, keeping everything you need one click away. It suits anyone who regularly shares links, Wi-Fi credentials, or data and wants a clean, no-clutter tool that simply works.

  1. Open Codex and choose Scan or Generate from the main screen
  2. To scan, hold a QR code in front of your camera or load an image file from your PC
  3. To generate, enter your text, URL, or data and pick a color and resolution
  4. Save or share the result directly from the app
  5. Revisit any past scan in the History section whenever you need it again

Controls

Everything is operated with standard mouse clicks and keyboard input — no special gestures required. The interface puts scanning, generating, and history in clearly labelled sections so you never have to hunt for a feature.

Tips & Tricks

  • Use the Read from Screen option to decode a QR code already visible on your monitor without needing a camera at all
  • When generating a QR code for a long URL, bump up the resolution setting so the code stays easy to scan when printed small
  • Enable the auto-open link option if you scan a lot of web addresses — it takes you straight to the page without an extra click
  • Check the History section before regenerating a code you have made before; your previous settings are saved there and ready to reuse
