Microsoft Visio 2021 Professional features

Visio 2021 Professional is built for IT professionals, engineers, architects, and business analysts who need to create, share, and maintain complex technical and business diagrams.

• BPMN 2.0 support – business process model and notation diagrams compliant with the BPMN 2.0 specification
• Network and IT diagrams – rack, detailed network, Active Directory, LDAP directory, and physical network layouts
• Engineering diagrams – electrical, piping and instrumentation, fluid power, industrial controls, process flow, and systems diagrams
• Floor plans and facilities – HVAC, plumbing, security, space planning, electrical, and site diagrams including the new Crime Scene Investigation template with Evidence, Indoor, and Outdoor stencils
• Mobile app wireframes – new mobile app wireframe templates for low-fidelity design sketches and high-fidelity prototypes
• Live Preview – preview shape and formatting changes before applying them, reducing trial and error when editing complex diagrams
• Diagram validation – built-in validation engine checks diagrams against defined rules and flags errors automatically
• Stock images library – access to a curated library of stock images and icons from the Office Premium Creative Content collection, insertable directly into diagrams
• Hex color input – enter Hex color values directly in the Colors dialog without converting to RGB manually
• Modernized interface – refreshed Start experience, updated ribbon with monoline iconography, and a cleaner overall design aligned with modern Microsoft applications

What is new in Visio 2021 Professional vs Visio 2019

Visio 2021 Professional includes everything from the 2019 version plus meaningful additions across cloud diagramming, templates, and usability:

• Expanded Azure stencils – significantly more Azure shapes covering additional services, configurations, and topology types not present in 2019
• New AWS stencils – Amazon Web Services shapes were not available in Visio 2019 – fully added in 2021
• Mobile app wireframe templates – new category of templates for mobile interface design not present in 2019
• Live Preview – ability to preview changes before committing them – a workflow improvement absent in the 2019 version
• Stock images and icons – Office Premium Creative Content library integration not available in 2019
• Hex color input – small but practical addition that eliminates color conversion friction
• Refreshed interface – modernized Start screen, updated ribbon iconography, and improved overall visual consistency

For teams needing the most current Visio release with the latest stencils and templates, Microsoft Visio 2024 Professional is the newest available version.

Frequently asked questions

Does Visio 2021 have an end-of-support date?
Unlike older Visio versions that followed a fixed 10-year lifecycle, Visio 2021 follows Microsoft’s Modern Lifecycle Policy. This means it receives continuous support with no fixed end-of-support date announced – support continues as long as the product remains actively licensed and used.

Can I use Visio 2021 Professional on a Mac?
No. Microsoft Visio is a Windows-only application and has never had a native macOS version. It is not compatible with macOS, iOS, Android or Chromebook. If you are on macOS, third-party diagramming tools are the alternative.

What is the difference between Visio 2021 Professional and Standard?
Professional adds data-linked diagrams, the full Azure and AWS stencil library, engineering templates, UML 2.5, BPMN 2.0, database model diagrams, and mobile wireframe templates. Standard covers flowcharts and basic diagramming without data connectivity or the extended template library. If you need any of the advanced template categories or data-linked functionality, Professional is the correct choice.

Can I open Visio 2019 files in Visio 2021?
Yes. Visio 2021 Professional is fully backward compatible with files created in Visio 2019 and earlier versions. Your existing diagrams open, edit, and save without any conversion required.

Is Visio included in Microsoft Office or Microsoft 365?
No. Visio is sold separately from all Microsoft Office editions and is not included in any Office bundle. A lightweight version of Visio is available within Microsoft 365 commercial subscriptions as Visio for the web, but the full desktop application requires a separate purchase or Visio Plan 2 subscription.
