Workflow
How it works
Paste Your Code
Paste a function, snippet, or pseudocode into the input box, or describe your process in plain language.
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.
Refine the Diagram
Switch layout direction, adjust colors, toggle connection labels, and drag nodes to fine-tune your chart.
Export or Share
Download PNG/SVG for your README or slide deck, or share a live link for team review and embedding.

FAQ
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.
Can I reverse-engineer code to a flow diagram online?
Yes. Paste any function or snippet and the AI produces a readable flow diagram that maps your code structure visually. It is a fast way to document legacy code, prepare for code reviews, or explain logic to non-technical stakeholders.
Can I export and embed the flowchart?
Yes. Export PNG or SVG for documents, slides, and READMEs. Share a live link for quick reviews or embed the chart in knowledge bases, wikis, and internal portals with a simple embed code.
Does it support large functions or multiple files?
Moderate-size functions work well in the free version. For very large inputs, break the code into logical sections for cleaner results. Pro file upload helps streamline bigger conversions and multi-function flows.
How do I label Yes/No branches on a decision node?
Turn on Show Connection Labels in Display Settings and edit the label text on each branch directly. Use the arrow size and line width controls to add visual emphasis to key decision paths.
Is my code secure?
Your input is processed only to generate the diagram and stays under your control. No sign-up is required, you decide what to share, and you can export locally or delete charts from your workspace at any time. Avoid pasting sensitive credentials or secrets.
