What is Flowchart Maker?

Drag and drop to build flowcharts with decision diamonds, process boxes, input/output parallelograms, document shapes, and connectors. Export the finished diagram as PNG, SVG, or PDF.

Pick from process boxes, decision diamonds, start/end pills, input/output parallelograms, and document shapes. They snap into place and stay connected when you move them. Double-click a node to rename it, drag from one handle to another to wire two shapes together, and recolor or clear the board in a click. When the diagram is done, export a transparent SVG for slides, a PNG at any zoom level, or a print-ready PDF.

How to use

1. Step 1 — Drag shape nodes (process, decision, start/end) from the toolbar onto the canvas.
2. Step 2 — Connect nodes by dragging from one handle to another. Double-click to edit labels.
3. Step 3 — Arrange your layout, then export the flowchart as PNG, SVG, or PDF for presentations, print, or documentation.

When to use

• Documenting a backend request flow with success and failure branches before you start writing code.
• Mapping a customer-support escalation path so a new hire can read it on day one.
• Sketching an algorithm in a design doc when prose stops being clear enough.

Result

A product manager maps out a user onboarding flow: Start → Sign Up → Email Verified? (decision) → Yes → Dashboard / No → Resend Email → loop back to verification.

FAQ

What is the difference between a process box and a decision diamond?

Rectangles represent an action or step (Send Email, Update Record). Diamonds represent a yes/no or branching question that splits the flow into two paths. Pill-shaped nodes mark the Start and End of the whole diagram. Following these conventions keeps the flowchart readable.

How do I connect two shapes?

Hover over a node and you will see small handles appear on its edges. Click and drag from one handle to another shape's handle, then release. An arrow appears between them. You can drag the arrow's midpoint later to reroute it cleanly around other nodes.

Can I label the arrows, not just the boxes?

Double-click an arrow and a text input appears at its midpoint. This is useful on decision diamonds to label the two outgoing branches Yes and No, or to annotate transitions with a condition such as status=200 or retry exhausted.

Why should I export as SVG instead of PNG?

SVG stays sharp at any zoom level and is editable in Figma, Illustrator, or Inkscape if you need to tweak text or colours later. PNG is fixed resolution but pastes more reliably into Confluence, Notion, or PowerPoint without import quirks.

How many nodes can the canvas handle before it slows down?

React Flow renders comfortably with a few hundred nodes. Past that, panning and zooming get sluggish on lower-end laptops. If your diagram grows that large, split it into a top-level overview that links to detail diagrams for each subsystem.
