About .pnt Files
PNT files are graphic images used by older painting applications.
They come in two flavors. One is linked with Prism Paint via the application/octet-stream MIME type. The other is tied to MacPaint Graphics through the image/mac MIME type.
These files store simple, raster-based drawings and sketches in a binary format.
- Prism Paint Use: Contains proprietary binary data for a dedicated painting program.
- MacPaint Use: Holds classic MacPaint graphics, used on early Macintosh systems.
- They can be opened with legacy graphics software and some modern editors like GIMP or Adobe Photoshop (with proper plugins).
According to FilExt.com, these files remain a notable part of early digital art history.
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.

FAQs
What is a .pnt file?
A .pnt file is predominantly a bitmap image created by MacPaint, a pioneer graphics program for the original Apple Macintosh. It stores black-and-white graphics at a resolution of 72 DPI. Alternatively, the extension may be used by Prism Paint for its proprietary binary data.
How do I open a .pnt file on Windows?
You can view MacPaint .pnt files using universal image viewers like XnView MP or Corel PaintShop Pro. Because this is a legacy format, standard Windows apps like Photos or Paint will likely not recognize it.
How can I convert a .pnt file to JPG or PNG?
Open the file in a compatible viewer like GraphicConverter (macOS) or XnView (Windows) and select File > Save As. Converting to PNG is recommended to preserve the quality of the original black-and-white pixel art.
What MIME type is used for .pnt files?
MacPaint graphics are associated with the MIME type image/mac or sometimes image/x-macpaint. If the file belongs to Prism Paint, it is often treated as generic binary data using application/octet-stream.
Why can't I open my .pnt file in Adobe Photoshop?
Modern versions of Adobe Photoshop have dropped support for many obsolete file formats, including MacPaint. You may need to use a format converter or an older version of the software to access the image.
How do I view .pnt files on a Mac?
The most reliable tool for opening legacy Mac formats on modern macOS is GraphicConverter by LemkeSoft. Native tools like Apple Preview generally no longer support the MacPaint format.
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.
