About this app

Editor for Visio Diagrams is a native Microsoft Visio (.vsdx) editor for creating, opening, and editing professional diagrams — without converting them to images or losing structure.

Work with real Visio files. Open .vsdx drawings, edit shapes and connectors on a modern canvas, and save changes back with high fidelity so your diagrams stay editable and compatible.

CREATE & EDIT
• Start a blank diagram or open existing .vsdx files
• Draw rectangles, ellipses, lines, and glued connectors
• Drop flowchart and technical shapes from a searchable stencil library
• Move, resize, rotate, align, group, and arrange shapes with precision
• Use smart guides, grid snapping, and multi-select for clean layouts
• Edit labels, styles, themes, and diagram properties
