Handy utilities for tech tasks

These utilities help with everyday technical jobs: making QR codes for websites and WiFi networks, creating strong random passwords, and formatting or checking JSON data from APIs and configuration files.

Because they run entirely in your browser, they're safe to use with sensitive information like WiFi passwords, API responses and new account passwords. Nothing is sent to a server or stored.

Quick tips

  • Print a WiFi QR code for guests so they can join your network without typing the password.
  • Use a different password of 16 or more characters for every important account.
  • Getting an error from an API? Paste the response into the JSON Formatter to find the exact line that's wrong.
