Flowchart Maker
Build process diagrams, decision trees, and workflows — right in your browser. No account, no upload, nothing sent to a server. Your diagram lives in local storage until you clear it or export it.
Tool Details
Design Professional Flowcharts with Drag-and-Drop Simplicity
Flowcharts are one of the easiest ways to visualize processes, algorithms, workflows, and decision-making logic. Whether you're documenting business operations, designing software architecture, explaining an algorithm, or planning a project, a well-designed flowchart makes complex ideas much easier to understand.
The Flowchart Maker on CoolDev.Tools lets you create professional flowcharts directly in your browser without installing any software.
The editor includes commonly used flowchart symbols such as:
- Process (Rectangle)
- Decision (Diamond)
- Terminal (Rounded Rectangle)
- Input/Output (Parallelogram)
- Predefined Process (Double-Lined Rectangle)
- Document (Wavy-Bottomed Rectangle)
Once your flowchart is complete, you can export it as PNG or SVG for presentations, documentation, websites, or sharing with your team.
Everything runs inside your browser, giving you a fast and responsive editing experience.
What is a Flowchart?
A flowchart is a visual representation of a process or workflow using standardized symbols connected with arrows.
Instead of reading long paragraphs or complicated documentation, users can understand a process simply by following the flow of connected shapes.
Flowcharts are commonly used in:
- software development
- business process documentation
- education
- project planning
- manufacturing
- quality assurance
Why Use Flowcharts?
Flowcharts simplify complicated ideas.
They help teams communicate processes more effectively while making workflows easier to understand.
Some major benefits include:
- better documentation
- easier debugging
- improved collaboration
- visual decision-making
- simplified training
Flowchart Symbols Available
The Flowchart Maker includes the most commonly used standard flowchart symbols.
Process (Rectangle)
The Process symbol represents an action or operation performed during a workflow.
Examples:
- Validate User
- Calculate Total
- Save Record
- Generate Invoice
This is the most frequently used flowchart shape.
Decision (Diamond)
A Decision symbol represents a condition where the workflow branches into multiple paths.
Examples:
- Is Payment Successful?
- User Logged In?
- Stock Available?
Decision nodes typically have:
- Yes
- No
or
- True
- False
branches.
Terminal (Rounded Rectangle)
The Terminal symbol represents the beginning or end of a process.
Examples:
- Start
- End
Every flowchart usually begins and ends with a terminal.
Input / Output (Parallelogram)
This symbol represents data entering or leaving a system.
Examples:
- Enter Username
- Read CSV File
- Display Result
- Print Report
Predefined Process (Double-Lined Rectangle)
A predefined process represents another reusable process or subroutine.
Instead of repeating detailed steps, the flowchart references an existing process.
Examples:
- Authenticate User
- Payment Gateway
- Send Email
Document (Wavy-Bottom Rectangle)
The document symbol represents a generated or used document.
Examples:
- Invoice
- Report
- Receipt
- PDF Export
Common Flowchart Examples
Flowcharts are useful in many industries.
Software Development
Visualize algorithms and application workflows.
Business Process Mapping
Document approval workflows and operational procedures.
API Design
Illustrate request-response flows and backend processes.
Education
Explain programming logic and decision trees visually.
Project Planning
Break complex projects into manageable workflow diagrams.
Features of the Flowchart Maker
The Flowchart Maker on CoolDev.Tools includes everything needed to build professional diagrams.
Browser-Based Editor
Create flowcharts directly in your browser.
No software installation required.
Standard Flowchart Shapes
Supports commonly used symbols including:
- Process
- Decision
- Terminal
- Input/Output
- Predefined Process
- Document
Drag-and-Drop Editing
Move and arrange shapes visually with ease.
Connect Shapes Visually
Create clear workflows using connector lines between symbols.
Fast Performance
The editor runs entirely in your browser for a smooth editing experience.
Export as PNG
Generate high-quality PNG images suitable for:
- presentations
- documentation
- blogs
- reports
Export as SVG
Export scalable vector graphics for:
- websites
- documentation
- Figma
- Adobe Illustrator
- further editing
SVG files remain sharp at any size without losing quality.
How to Create a Flowchart
Using the editor is simple.
Step 1: Add Flowchart Shapes
Choose the required symbols from the available flowchart elements.
Step 2: Arrange the Workflow
Drag shapes into position.
Step 3: Connect the Symbols
Create connections between steps to represent the workflow.
Step 4: Label Each Step
Add meaningful names to every process or decision.
Step 5: Export Your Diagram
Download your completed flowchart as:
- PNG
- SVG
Why Export as SVG?
Unlike raster images, SVG graphics remain perfectly sharp at any resolution.
SVG is ideal for:
- documentation
- websites
- technical blogs
- presentations
- editing later
PNG is better suited for quick sharing or inserting into office documents.
Browser-Based vs Desktop Flowchart Software
Traditional diagram software often requires installation, licensing, or user accounts.
Browser-based tools offer several advantages:
- instant access
- cross-platform compatibility
- no installation
- faster workflow
- works on Windows, macOS, Linux, and Chromebooks
Best Practices for Creating Flowcharts
Keep Workflows Simple
Avoid unnecessary complexity.
Use Standard Symbols
Following industry-standard shapes improves readability.
Maintain Consistent Flow Direction
Most diagrams read from top to bottom or left to right.
Use Clear Labels
Each step should describe exactly what happens.
Avoid Crossing Connector Lines
Cleaner diagrams are easier to understand.
Frequently Asked Questions (FAQs)
What is a flowchart?
A flowchart is a diagram that visually represents a process or workflow using standardized symbols connected by arrows.
Can I export my flowchart?
Yes. The editor supports exporting diagrams as both PNG and SVG.
Why choose SVG over PNG?
SVG files are vector graphics that remain sharp at any zoom level and are ideal for editing and web use.
Does this tool work in the browser?
Yes. Everything runs directly in your browser without installing software.
Is my diagram uploaded anywhere?
No. The editor is browser-based, allowing you to create diagrams without relying on external desktop software.
