Quick Facts
How it works
From code to clear flowchart in four steps.
Paste Your Code
Paste a function, snippet, or pseudocode into the input box, or describe your process in plain language.
Example: Paste a Python if/else function or type out your algorithm steps.
AI Builds the Flow
The AI converts your input into nodes and connections—if/else becomes a Decision node with Yes/No branches, loops become cycles.
Example: An if statement becomes a Decision node with Yes and No paths.
Refine the Diagram
Switch layout direction, adjust colors, toggle connection labels, and drag nodes to fine-tune your chart.
Example: Enable Show Connection Labels, then switch layout to left-to-right.
Export or Share
Download PNG/SVG for your README or slide deck, or share a live link for team review and embedding.
Example: Export PNG for a Confluence page or share a link with your code reviewer.
Who uses it
From code reviews to classroom lessons—clear flows for every team.
Reverse-engineer logic
Turn functions and conditionals into visual process flows for code reviews, onboarding, and refactoring sessions.
Document test paths

FAQs
How does the code to flowchart converter online work?
Paste your code or describe your algorithm and the AI maps the logic into Start, Process, Decision, and End nodes. It applies auto-layout, adds Yes/No connection labels on decision branches, and produces an editable diagram you can review, adjust, and export in seconds.
Which programming languages are supported?
Common patterns in Python, JavaScript, Java, C/C++, and pseudocode convert well. The AI understands if/else, loops, function calls, and basic control flow across most imperative languages. You can always refine node labels and connections after the first draft.
Can I convert pseudocode to a flowchart?
Yes. Type or paste your algorithm steps in plain pseudocode and the AI builds a labeled flow with Decision nodes, Yes/No branches, and Process steps. It is ideal for teaching, documentation, and design work before writing actual code.
Is the code to flowchart converter really free?
Yes. You can use the converter free in your browser with no installation or sign-up required. Pro plans add file uploads, advanced customization, and higher AI usage limits for teams with larger conversion needs.
How accurate are AI-generated flowcharts?
For typical control flow—if/else, loops, function calls—accuracy is high. Review the draft and edit node labels, arrow directions, and branch names as needed. Auto-layout keeps the diagram readable as you refine it.
