Is Flowchart Designer completely free?

Yes, Flowchart Designer is 100% free with no hidden fees, subscription plans, or watermarks on your exported images.

How do I connect two nodes?

Hover over any node to reveal the four blue connection ports (top, right, bottom, left). Click and drag from any port, then release on a port of another node to create an arrow connection.

Can I change connection routing style?

Yes! Use the sidebar to choose between Curved (bezier), Straight, and Orthogonal (right-angle) routing. You can also change the routing of an existing connection by selecting it and editing in the Properties Panel.

How do I edit a node's label?

Double-click any node to edit its label inline directly on the canvas. Press Enter or click away to confirm. You can also edit the label in the Properties Panel on the right side.

What export formats are available?

You can export your flowchart as a high-resolution PNG image at standard (1x) or high-DPI (2x) resolution using the Export button in the top toolbar.

About Flowchart Designer

Flowchart Designer is a free, privacy-first, browser-based tool for creating professional flowcharts and process diagrams. No sign-up. No server uploads. Just open and design.

Why We Built It

Most flowchart tools are either locked behind expensive subscriptions, require account creation, or send your data to the cloud. We built Flowchart Designer to be a fast, lightweight alternative that respects your privacy and runs entirely in your browser using modern web technologies.

Technology

Built with vanilla JavaScript, W3C SVG for connection rendering, HTML5 Canvas API, and Vite as the build tool. Designed with Schema.org structured data specs from Schema.org.
