A Circuit Diagram Maker

Circuit Diagram enables you to make electronic circuit diagrams and export them as images.

The latest source code for Circuit Diagram can now be found on GitHub.

Official Website

The official website for Circuit Diagram can now be found at - please visit for requesting new features and components in future releases, help and documentation on designing circuits, and more.
If you would like to link to us, please link to rather than this page - thanks!

Custom Components

In addition to the standard components, Circuit Diagram supports custom components - you can download more components and learn how to create your own.


Design your electrical circuit and then export it as:
  • PNG - best compatibility
  • SVG - no loss of quality when scaling

Currently supported components:
  • Logic gate (AND, NAND, OR, NOR, XOR, NOT, Schmitt Trigger NOT)
  • Resistor (including variable, thermistor, potentiometer)
  • Capacitor
  • Op-amp
  • LED & diode
  • Microcontroller
  • 4-bit counter
  • 7-segment decoder
  • 7-segment display
  • Lamp
