Circuit Diagram Maker
Quick answer: Create professional circuit diagrams online with supported-model circuit analysis. 480+ symbols across 4 packs, smart wire routing, BOM export, and PNG, SVG, and PDF output.
Best fit
Use this browser workflow when an editable drawing, structured electrical data, fast sharing, and common exports matter more than a native specialist desktop format.
Not the best fit
Use specialist software when the project requires native DWG intelligence, enterprise plant engineering, advanced production PCB/DFM, arbitrary vendor simulation models, certified power studies, or mechanical panel engineering.
Available capabilities
- 480+ circuit symbols
- Supported-model DC, transient, and AC analysis
- Editable pin-aware routing
- PNG, SVG, PDF, DXF, netlist, and BOM outputs
Representative test
Open a relevant sample, change one component and connection, then verify the exact drawing, report, analysis, and export your job requires.

Frequently asked questions
Is CircuitDiagramMaker free to use?
Yes. The free plan lets you create up to 3 diagrams with 3 exports per month and includes the DIY symbol pack (84 symbols) and DC simulation. Upgrade for unlimited diagrams, all 480+ symbols, and supported DC, transient, and AC analysis.
Does CircuitDiagramMaker have circuit simulation?
Yes. The built-in browser engine supports DC operating point, transient, and AC frequency analysis for supported component models. The compatibility page documents model and syntax limits.
Can I export my circuit diagrams?
Absolutely. Export as high-resolution PNG, scalable SVG, print-ready PDF, or Bill of Materials CSV. PNG and SVG are instant client-side exports; PDF is server-side for print-perfect output.
Does it protect unsaved work?
Yes. The editor stores a local recovery copy in IndexedDB and authenticated diagrams autosave to the server. A connection is still required to load and sync the web application.
How many circuit symbols are available?
Over 400 symbols are available across DIY, Hobbyist, Pro, and Industrial packs. Standard-specific details are stated only where they have been defined for that symbol.
Can I share my diagrams with others?
Yes. Generate a private, unlisted, or public shareable link for any diagram. Viewers see a read-only version without needing an account. Full version history with restore is included.
Is there a circuit diagram maker app or online version?
CircuitDiagramMaker is an online editor with no desktop installation. It runs in modern browsers on Windows, Mac, Linux, Chromebook, tablets, and phones.
Is this a free circuit diagram maker online?
Yes. You can draw, edit, and export circuit diagrams online free on the starter plan — no credit card and no signup required to begin. Paid plans add unlimited diagrams, all 480+ symbols, and supported DC, transient, and AC analysis.
Can I use it as a circuit diagram web editor with a simulator?
Yes. Place components, wire them, then run DC, transient, and AC analysis for supported models in the browser. The compatibility matrix documents model and syntax limits.
