Frequently Asked Questions
What types of diagrams can I make?
Flowcharts, mind maps, org charts, Venn diagrams, Gantt charts, decision trees, timelines, process diagrams, cycle diagrams, pyramids, hierarchies, roadmaps, SWOT analyses, and more.
Is this a drawing tool?
No — each diagram type has a structured editor. You enter data (steps, nodes, items) and the tool generates the visual. Much faster than drawing from scratch.
Can I combine multiple diagrams?
Yes. Open /editor to place any diagram type alongside charts, stat cards, text, and images on a single infographic canvas.
Is it free?
All diagram types are free with no watermark. Export as PNG at no cost. No signup required.
Can I use it for presentations?
Yes. Export at high resolution and paste directly into PowerPoint, Google Slides, or Keynote.
What is the difference between a flowchart and a process diagram?
A flowchart includes decision branches (yes/no diamonds). A process diagram shows sequential steps without branching. Use /tools/flowchart-maker for decisions, /tools/process-diagram-maker for linear processes.
