IGCSE Flowchart Symbols
Our algorithm ensures that your flowchart perfectly matches the requirements for Cambridge IGCSE (0478), O-Level (2210), and A-Level (9618).
We automatically detect I/O operations, process assignments, and complex branching decisions to output the correct industry-standard shape.
- ✔️ Automatic Shape Mapping
- ✔️ 100% Client-Side Rendering
- ✔️ Flowchart to Pseudocode Sync

Frequently Asked Questions
How do I convert pseudocode to a flowchart?
Simply type your pseudocode into our free compiler, run it to ensure there are no syntax errors, and click 'Code to Flowchart'. Our engine will automatically generate a flowchart using standard IGCSE symbols.
What are the standard IGCSE flowchart symbols?
The standard symbols are: Rounded Rectangle for Start/End, Parallelogram for Input/Output, Rectangle for Process/Assignment, and Diamond for Decisions (IF/WHILE/FOR).
Can I convert a flowchart back to pseudocode?
Yes! PseudoStudio allows you to edit the generated flowchart visually. Once done, you can click "Sync Edits to Code" to generate the updated pseudocode from your flowchart.
