How to draw a flowchart

  1. Add the steps. Use a process for an action and a decision for a condition.
  2. Connect the logic. Add arrows, label branches, and connect a later step back to an earlier one for a loop.
  3. Save a copy. Export JSON to keep editing later, or PNG, SVG, or PDF to share the diagram.

Common questions

Is the editor free?

Yes. The editor, browser saves, and JSON, PNG, SVG, and PDF exports are free. No account or payment is required. There are no ads or analytics.

Where are my flowcharts saved?

Projects are stored in IndexedDB in this browser on this device. Diagram content is not uploaded to a server. Clearing site data or using a private browsing session can remove your work. Export JSON backups for work you want to keep.

Can I use it for branches and loops?

Yes. Connect decision branches and label their arrows. Create a loop by connecting a later step to an earlier step. A connection directly from a node to itself is not supported.

Does it turn a flowchart into code?

No. This version is a diagram editor. It does not execute algorithms or generate source code.
