Which MIME types are related to file extension ".vssx"?
The .vssx file extension is associated with 3 MIME types:
application/vnd.ms-visio.stencil, application/vnd.ms-visio.stencil.main+xml, application/vnd.visio.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .vssx Files
VSSX files are Microsoft Visio stencil documents that store a collection of shapes for diagramming purposes. They use the Office Open XML format and are macro-free.
Their MIME types include application/vnd.ms-visio.stencil, application/vnd.ms-visio.stencil.main+xml, and application/vnd.visio, which indicate that these files are designed for Visio and include essential data in XML format inside a ZIP container.
- Reusable Shapes: They serve as building blocks in creating flowcharts and technical diagrams.
- Consistent Design: They help maintain uniformity across diagram elements.
- Compatibility: They work primarily with Microsoft Visio and similar diagramming tools that support Office Open XML.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.
Associated MIME types

FAQs
What is a VSSX file used for?
A .vssx file is a Microsoft Visio Stencil file that contains a collection of reusable shapes, connectors, and icons. It acts as a library or palette that allows users to drag and drop pre-defined elements onto a .vsdx drawing canvas to create flowcharts and diagrams efficiently.
How do I open a VSSX file?
You can open VSSX files using Microsoft Visio (version 2013 or later) by double-clicking the file or loading it into the 'Shapes' pane of an active diagram. Third-party tools like LibreOffice Draw, Lucidchart, and diagrams.net (formerly Draw.io) also support importing these stencil files.
What is the difference between VSS and VSSX?
The .vss extension represents the older, binary format used in Visio 2010 and earlier, while .vssx uses the newer Office Open XML format introduced in Visio 2013. The VSSX format is essentially a ZIP archive containing XML data, making it more compact and less prone to corruption.
Are VSSX files safe from macro viruses?
Yes, .vssx files are strictly macro-free documents. Unlike the older .vss format or the macro-enabled .vssm format, a VSSX file cannot store or execute VBA code, making it a safer choice for sharing standard shape libraries.
How can I convert a VSSX file to PDF or image formats?
You cannot directly 'convert' a stencil to a PDF in the traditional sense, as it is a collection of objects rather than a single page. However, you can drag all the shapes from the VSSX file onto a blank Visio drawing page and then save that drawing as a PDF, JPG, or PNG.
Why can't I edit the shapes in my VSSX file?
Visio opens stencils in read-only mode by default to prevent accidental modification of the master shapes. To make changes, right-click the stencil's title bar in the Shapes pane and select Edit Stencil; a small asterisk icon will appear indicating it is now editable.
What is the MIME type for VSSX files?
The standard MIME type for these files is application/vnd.ms-visio.stencil. For more technical details on Visio media types, you can refer to the entry for application/vnd.visio or application/vnd.ms-visio.stencil.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
