What is MIME type "image/x-wpg"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

The MIME type image/x-wpg identifies graphics made for specific word processing software. It is used to embed detailed image data into documents. The file used is WPG.

This format stores graphics in a way that preserves clarity for print and screen rendering. Modern image viewers may not support it without conversion, and specialized software like WordPerfect Office is often required.

Main use: Embedding graphics in word processing or desktop publishing documents.
Functionality: Manages detailed image data for crisp display and printing.
Technical note: The prefix x- shows it is an experimental or non-standard MIME type often tied to proprietary software.

Usage Examples

HTTP Header

When serving content with this MIME type, set the Content-Type header:

    <a href="file.dat" type="image/x-wpg">Download file</a>

Server-side (Node.js)

Setting the Content-Type header in Node.js:


    const http = require('http');

      res.end('Content here');    
    }).listen(3000);

FAQs

Do web browsers support image/x-wpg?

No, modern browsers like Chrome, Firefox, and Safari do not support the image/x-wpg MIME type natively. If you embed a .wpg file in a webpage, it will likely appear as a broken image icon or trigger a file download. You must convert these files to standard web formats like image/png or image/jpeg for them to display correctly.

How do I open a file sent with the image/x-wpg content type?

You need software compatible with the WordPerfect Graphics format. The primary application is Corel WordPerfect Office, but free alternatives like LibreOffice and Inkscape can often import and view these files. Dedicated image viewers like IrfanView or XnView also support the format.

How do I configure Apache to serve .wpg files correctly?

To ensure your server sends the correct Content-Type header, add the following line to your .htaccess file or main configuration: AddType image/x-wpg .wpg. This helps client applications identify the file as a WordPerfect graphic rather than a generic binary file.

What does the 'x-' prefix mean in image/x-wpg?

The x- prefix signifies that this is a non-standard or proprietary MIME type that is not part of the official IANA registry. It indicates the format was developed privately (in this case, by WordPerfect Corporation) rather than by an internet standards body.

How do I convert image/x-wpg for use on a website?

Since .wpg files can contain both vector and bitmap data, the best conversion target depends on the image content. Use LibreOffice Draw to open the file and export it as image/svg+xml to preserve vector scalability, or export it as a PNG if it contains complex raster data.

Why does Nginx identify my WPG files as application/octet-stream?

Nginx defaults to application/octet-stream if it doesn't recognize the file extension. To fix this, open your mime.types file (usually in /etc/nginx/) and add the line image/x-wpg wpg;, then reload the server configuration.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
