Electrical Diagram Maker
Quick answer: Create electrical diagrams for residential, commercial, and industrial applications. Add structured device and wire data, then generate live device, wire, cable, terminal, PLC I/O, and load schedules.
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
- Structured device, wire, cable, and terminal data
- Live PLC I/O and load schedules
- Multi-sheet drawings and title blocks
- PNG, SVG, PDF, DXF, and CSV outputs
Representative test
Open a relevant sample, change one component and connection, then verify the exact drawing, report, analysis, and export your job requires.
Other tools buyers evaluate
AutoCAD Electrical, SmartDraw, Visio, EdrawMax. Verify each vendor’s current primary documentation before purchase; this page does not claim feature parity.
Frequently asked questions
What types of electrical diagrams can I create?
Wiring diagrams, circuit schematics, panel layouts, single-line diagrams, industrial control diagrams, multi-page drawings with title blocks, and more.
Does it support industrial control panel design?
Yes. The Industrial symbol pack (160 symbols) covers all components for control panels: contactors, overload relays, motor starters, VFDs, PLCs, terminal blocks, and safety relays. Pre-built templates for DOL and star-delta starters are included.
Is there circuit simulation?
Yes. The browser engine supports DC, transient, and AC analysis for a documented set of component models, with waveform and schematic result views.
How does version history work?
Every save creates a snapshot. You can browse, compare, and restore any previous version of your diagram.
What export formats are supported?
PNG and SVG (instant, client-side), PDF (server-side, print-ready), and BOM CSV for component procurement.
Is there free electrical wiring diagram software to download?
You do not need to download any electrical wiring diagram software — this electrical diagram maker is free to start and runs online in your browser on Windows, Mac, and Linux. Nothing to install.
Is this electrical diagram maker online and free?
Yes. Draw online on the starter plan with no signup required to begin. Paid plans add unlimited diagrams, symbol packs, engineering schedules, and additional simulation analyses.
Can it replace desktop electrical CAD for wiring diagrams?
For most wiring diagrams, panel layouts, and control schematics, yes — it offers 480+ symbols, multi-page drawings with title blocks, DXF and SPICE export, and BOM, all in the browser with no CAD install.
