What Is a Flowchart Maker?

A flowchart maker is a tool that lets you visually map out processes, decisions, and workflows using standardized shapes and connecting arrows. Flowcharts use rectangles for process steps, diamonds for decisions, ovals for start/end points, and parallelograms for input/output — a visual language understood across industries worldwide.

Flowcharts were first introduced in the 1920s by industrial engineers Frank and Lillian Gilbreth and became a standard tool in computer science during the 1960s. Today, they remain one of the most effective ways to document processes, communicate workflows, and solve problems visually. Over 80% of Fortune 500 companies use flowcharts in their process documentation.

This flowchart maker runs entirely in your browser with zero setup. Drag shapes from the sidebar, connect them with arrows, customize colors and text, and export your finished diagram as PNG, SVG, or JSON. No account required, no data leaves your device.

How to Create a Flowchart

Drag shapes from the sidebar. The shape library includes six types: rectangles for processes, diamonds for decisions, ovals for start and end points, parallelograms for data input/output, circles for on-page references, and text boxes for annotations. Drag any shape onto the canvas to place it.

Connect shapes with arrows. Hover over any shape to reveal its four connection ports. Click a port and drag to another shape's port to create an arrow connector. Choose between straight, right-angle, and curved connector styles from the toolbar dropdown.

Edit text and style. Double-click any shape to type text inside it. Use the properties panel on the right to change fill color, border color, text size, and dimensions. Shapes snap to a 20-pixel grid for clean alignment, which you can toggle off for freeform placement.

Export or save your work. Download as a high-resolution PNG for presentations, SVG for scalable vector output, or JSON to save and reload your diagram later. Use the Import button to load any previously saved JSON file.

Key Features

Six shape types with standard flowchart semantics. Each shape communicates a specific meaning: rectangles for actions, diamonds for yes/no decisions, ovals for terminals, parallelograms for I/O operations, circles for connectors, and dashed text boxes for notes and labels.

Three connector styles. Straight connectors for simple flows, right-angle (orthogonal) connectors for structured diagrams that follow grid lines, and smooth curved (bezier) connectors for organic-looking diagrams. All connectors include directional arrowheads.

Undo/redo and keyboard shortcuts. Every action is tracked with a 50-step history. Use Ctrl+Z to undo and Ctrl+Shift+Z to redo. Delete selected shapes with the Delete or Backspace key. Shift-click to select multiple elements.

Built-in templates. Start from a blank canvas or choose from three templates — Basic Flowchart, Decision Tree, and Org Chart — to jumpstart your diagram. Templates provide a pre-built structure you can customize with your own content.

Flowchart Maker: Free vs Paid Alternatives

vs Lucidchart ($7.95/mo) — Lucidchart is the market leader with real-time collaboration, 1,000+ templates, and integrations with Google Workspace and Microsoft 365. However, the free tier limits you to 3 editable documents with 60 shapes each. Our tool has no limits — create unlimited flowcharts with unlimited shapes, all free.

vs diagrams.net / draw.io (free) — diagrams.net is a powerful free option with deep feature sets. The tradeoff is a steeper learning curve and a more cluttered interface. If you need a quick flowchart in under 5 minutes, our streamlined drag-and-drop approach is faster. For complex enterprise diagrams, diagrams.net may be worth the learning investment.

vs Microsoft Visio ($5/mo) — Visio is Microsoft's enterprise diagramming tool with deep Office 365 integration. It's overkill for most flowcharting needs and requires a paid subscription. Our tool covers the core flowcharting use case — shapes, connectors, text, export — without the enterprise complexity or cost.

vs Miro (free tier: 3 boards) — Miro is a collaborative whiteboard platform that includes flowcharting as one of many features. The free tier limits you to 3 boards. If you only need flowcharts (not whiteboarding, mind maps, and sticky notes), a dedicated flowchart maker is faster and simpler.

Frequently Asked Questions

Is this flowchart maker really free?

Yes, 100% free with no signup, watermarks, or usage limits. The tool runs entirely in your browser — nothing is uploaded to any server. Create as many flowcharts as you need and export them in PNG, SVG, or JSON format at no cost.

How do I connect shapes together?

Hover over a shape to reveal four connection ports (small circles on each side). Click and drag from one port to a port on another shape to create an arrow connector. You can choose between straight, right-angle (orthogonal), and curved connector styles from the toolbar.

Can I save and reload my diagrams?

Yes. Click the JSON export button to save your entire flowchart as a JSON file. To reload it later, click Import and select the JSON file. All shapes, connectors, text, colors, and positions are preserved exactly as you left them.

What export formats are available?

Three formats: PNG for high-resolution raster images perfect for presentations and documents, SVG for scalable vector graphics that stay crisp at any size, and JSON for saving and reloading your diagrams. The PNG export renders at 2x resolution for crisp output on retina displays.

Does the flowchart maker work on mobile?

The flowchart maker works on tablets and larger screens. For the best experience with drag-and-drop shape creation and precise connector placement, we recommend using a desktop or laptop computer. The canvas supports touch input for basic interactions on tablets.

What shapes are used in a flowchart?

Standard flowchart shapes include rectangles for process steps, diamonds for decision points (yes/no questions), ovals for start and end terminals, parallelograms for input/output operations, and circles for on-page connectors. Using the correct shapes makes your flowchart universally readable.

Can I export my flowchart as a PDF?

You can export as PNG or SVG. To create a PDF, export as SVG and open it in any browser — then use the browser's Print to PDF function. SVG exports produce crisp, scalable output perfect for documents.

What's the difference between a flowchart and a process map?

A flowchart shows the logical flow of a single process with decision branches. A process map is broader — it can show multiple processes, swim lanes for different teams, and cross-functional handoffs. Start with a flowchart for individual workflows, then upgrade to a process map for complex multi-team operations.

How do I add decision branches to a flowchart?

Add a diamond shape to represent your decision point. Connect it with arrows to two or more paths. Label each arrow with the decision outcome (Yes/No, True/False, or custom conditions). Each path continues to the next process step or decision.

What's the best free alternative to Lucidchart?

For quick flowcharts without signup, this tool is the fastest option — drag, drop, export. For more complex diagramming with collaboration, diagrams.net (formerly draw.io) is a strong free alternative. Lucidchart's free tier limits you to 3 editable documents and 60 shapes per document.
