Code → Flowchart Generator

Our Flowchart Generator supports JavaScript, Python, C, C++, and Java. It also accepts Pseudocode and Step-based logic descriptions. The engine uses language-specific tokenizers to accurately detect loops, conditionals, and function calls in each syntax.

All processing happens 100% client-side in your browser. The tool tokenizes your code, builds a lightweight Abstract Syntax Tree (AST), generates a Control Flow Graph (CFG), and renders the flowchart using SVG—all without sending data to any server. Your code remains completely private.

We follow standard flowchart conventions: Ovals for Start/End, Rectangles for Processes, Diamonds for Decisions (if/else/switch), Parallelograms for Input/Output, and Subroutine boxes for Function Calls. Loops use diamonds with back-edges to show iteration.

Yes! You can export your flowchart as a PNG image, SVG vector (scalable for print), or a PDF document. There's also an option to copy embeddable code for use in websites or documentation.

The Animate tab lets you visualize program execution step-by-step. Each node highlights in sequence with narration explaining what's happening—perfect for teaching, debugging logic, or preparing for coding interviews.

Absolutely. The Customize tab offers color themes (Default, Ocean, Forest, Sunset, Mono), adjustable font sizes, node spacing controls, and toggle options for line numbers and arrow labels. Switch between vertical and horizontal layouts too.

Yes! Click any node to see a tooltip showing the node type, source line number, and the exact code it represents. This line-by-line mapping helps you understand how your code translates to flow logic.

Yes! The core flowchart generation is completely free. Students can visualize algorithms for assignments, and teachers can use it to create educational diagrams. Pro features like advanced export and extended history are available with an upgrade.
