What is Circuit Diagram?
Circuit Diagram is a free, open-source application for drawing electronic circuit schematics. The classic Windows editor provides a visual workspace for arranging components and exporting the finished diagram as a PNG or SVG image. It is useful when you need a circuit illustration for documentation rather than a drawing made from unrelated shapes. Custom components can be defined in XML when the supplied collection does not include the symbol you need.
This download is version 3.1, listed by the publisher as Desktop (Classic), the original desktop application. Its release notes identify a searchable toolbox. The publisher now lists the browser editor and preview command-line tools separately; those are not the installer linked here. Do not assume that newer web-editor functions, including its simulation service, are included in this classic desktop release. The publisher's catalog describes this release as 11 years old, and modern Windows compatibility has not been verified for this entry.
What it offers
- Create electronic circuit diagrams with a collection of component symbols.
- Export diagrams as PNG images or scalable SVG files.
- Define additional components using an XML format.
- Find components with the searchable toolbox introduced in version 3.1.
Good to know
- The linked installer is the legacy Desktop (Classic) 3.1 release, listed by the publisher as 11 years old; modern Windows compatibility is unverified.
- The web editor and preview command-line tools are separate offerings; their newer features should not be assumed to exist in this desktop release.
