Try These Examples
Import and edit existing flowcharts
Bring in a basic flowchart from Draw.io, Visio (.vsdx/.vdx), a Lucidchart Visio export or Mermaid without using AI credits. Labels and connections become editable in our visual style; the original layout and artwork are replaced. SVG artwork and PNG/JPG/WebP images use AI conversion, so review the result. Our own editable SVG and JSON files reopen with their saved design.
What is a Flowchart?
A flowchart is a visual diagram that shows the steps in a process using shapes and arrows. Rectangles represent actions, diamonds represent decisions, and arrows show the flow from one step to the next.
Flowcharts make complex processes easy to understand. Whether you're documenting a business workflow, explaining how software works, planning a project, or making decisions, a well-designed flowchart communicates your ideas clearly.
Describe your process or upload an existing diagram to get started. Then click to edit labels, move or resize shapes, and connect steps with arrows. Download an editable file to keep working later.
Start with a simple description. You do not need to write diagram code or plan the layout first.

Create a flowchart from an idea or bring an existing diagram into the editor. You can review and change the result before downloading it.
Describe a process or upload a diagram
Explain what you want to show, including any decisions or exceptions. Or upload a basic flowchart from Draw.io, Visio, a Lucidchart VSDX export or Mermaid. You can also upload an SVG or image for AI conversion.
Generate or open your flowchart
AI turns your description into an editable diagram. Supported diagram files open without AI credits; SVG artwork and images use AI conversion. Check the labels and connections, especially after converting an image.
Edit shapes, labels and arrows
Double-click a shape to edit its label. Drag to move it, use its corner to resize it, or add shapes from the toolbar. To connect steps, choose an arrow style and click two shapes. Sign in to request AI edits, then review the proposed changes before applying them.
Export, save or share
Download an image for a document or presentation, or an editable SVG, JSON, Draw.io or VSDX file to continue working. Sign in to save to your account or create a share link. Manual edits and file exports are free.

What Can You Create?
Our flowchart generator works for any process you need to visualize. Here are some popular uses:
Business Processes
Document workflows like employee onboarding, customer support procedures, approval chains, or order fulfillment. Clear process flowcharts help teams work consistently and efficiently.
Software & Algorithms
Map out program logic, user flows, or decision trees before coding. Developers use flowcharts to plan systems and communicate technical concepts to non-technical team members.
Decision Making
Create decision flowcharts that guide users through complex choices. Perfect for troubleshooting guides, diagnostic procedures, or any scenario with multiple possible paths.
Education & Training
Teachers and trainers use flowcharts to explain processes, scientific concepts, and step-by-step procedures. Visual diagrams improve comprehension and make learning materials more engaging.
Flowchart Symbols and Their Meanings
These symbols explain common flowchart notation. The current editor provides process rectangles, decision diamonds, start/end shapes, text and several arrow styles. Other specialist symbols may be simplified when imported.
Rectangle (Process)
Represents an action or step in the process. Examples: "Send email," "Calculate total," "Review document."
Diamond (Decision)
Indicates a point where the flow branches based on a condition. Typically has yes/no or true/false outputs. Examples: "Is payment received?" "Approved?"
Oval (Terminator)
Marks the start or end of a process. Every flowchart should have at least one start and one end point.
Parallelogram (Input/Output)
Represents data entering or leaving the process. Examples: "Enter username," "Display results," "Print report."
Arrow (Flow Line)
Shows the direction of the process flow, connecting shapes in sequence.
Rectangle with Double Lines (Subprocess)
Indicates a predefined process or subroutine that's detailed elsewhere.
