Free Flowchart Maker Online — No Signup Required

A flowchart is a diagram that maps a process, decision tree, algorithm, or workflow as a sequence of shapes connected by arrows. Each shape type has a standard meaning: rectangles for process steps, diamonds for decision points (yes/no branches), ovals for start and end, parallelograms for input/output, and cylinders for data storage. Flowcharts are used in software engineering to document algorithms and system flows, in business process management to map workflows, in quality assurance to diagram test cases, and in technical writing to explain multi-step procedures.

This browser-based flowchart maker lets you place shapes, draw connections, and add labels without installing Visio, Lucidchart, or draw.io. The canvas supports pan and zoom for large diagrams. Shapes snap to a grid for alignment. Connectors route automatically between shapes and update when you move them. Export options include PNG for embedding in documents and SVG for high-resolution printing or editing in vector graphics tools.
