Free network diagram maker
Map physical or logical network topology with EdrawMax. Build diagrams for LAN/WAN environments, cloud architecture, security zones, racks, and infrastructure using editable templates plus Cisco, AWS, Azure, router, switch, server, firewall, and connection symbols.
Why use EdrawMax for network diagrams?
Start with editable examples for physical and logical networks, LAN/WAN topology, firewalls and DMZs, racks, Cisco environments, and AWS or Azure architectures. Replace sample devices, subnets, and connections with your actual infrastructure.
Use EdrawMax as an alternative workflow for teams that need editable network diagrams and Visio file compatibility. Import existing VSDX content when needed, refine the topology, and export the result for continued editing or documentation.
Build and revise topology diagrams with drag-and-drop symbols, connectors, alignment tools, labels, and annotations. A consistent visual system makes it easier to distinguish devices, zones, subnets, and data paths as the network grows.
Work on network diagrams from desktop or browser workflows and share updated diagrams with teammates. Keeping an editable source helps operations, security, and infrastructure teams maintain a common view as devices, subnets, or cloud services change.
Export the topology as PDF for documentation, SVG or images for presentations, or an editable format when others need to continue working on the diagram.
How to make a network diagram with EdrawMax
Start with a physical, logical, cloud, security, rack, or vendor-specific template, or open a blank canvas if you are documenting an existing environment from scratch.
Place routers, switches, firewalls, servers, endpoints, cloud services, or racks. Connect them with consistent lines, and label important subnets, VLANs, IP ranges, interfaces, or trust zones when they matter to the audience.
Check that the diagram distinguishes physical versus logical relationships clearly, remove unnecessary detail, then export or share the diagram for troubleshooting, onboarding, security review, or infrastructure documentation.
