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.
Our free flowchart generator lets you create these diagrams quickly without installing any software. Just drag shapes onto the canvas, add your text, connect the steps, and download your finished flowchart.

Making a flowchart is simple with our free online tool. Follow these steps to create your diagram in minutes.
Add Your Shapes
Start by dragging flowchart shapes onto the canvas. Use rectangles for process steps, diamonds for decision points, and ovals for start and end points. Position them in the order your process flows.
Connect the Steps
Draw arrows between shapes to show how the process moves from one step to the next. For decision points, add multiple arrows to show different paths based on yes/no or other conditions.
Add Your Text
Click on each shape to add labels describing what happens at that step. Keep text short and action-oriented — for example, "Review application" or "Send confirmation email."
Download Your Flowchart
When you're happy with your diagram, download it as an image. Use it in presentations, documents, websites, or anywhere you need to explain a process visually.

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
Flowcharts use standard shapes that have specific meanings. Understanding these symbols helps you create diagrams that others can easily read.
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.
