About .puz Files
PUZ files are binary files used for storing crossword puzzles. They contain grid layouts, clues, and answers in a compact format.
These files use the MIME type application/octet-stream. This MIME type indicates that the file holds non-text, binary data.
- Main use: Used for Across-style crossword puzzles.
- Other uses: Distributed for interactive puzzle solving and digital crosswords.
- Software: Open them with apps like Across Lite or other similar puzzle programs.
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.

How do I convert a .puz file to PDF for printing?
To print a puzzle, open the .puz file in a desktop viewer like Across Lite. Select the Print function from the file menu, and choose "Microsoft Print to PDF" (Windows) or "Save as PDF" (Mac) in the printer selection dialog to generate a printable document.
Why does the .puz file look like scrambled text in Notepad?
A .puz file is a binary format, not plain text. It contains encoded data for the grid layout, solution, and checksums alongside the clues. Because of this structure, viewing it in a text editor will display unreadable characters; it requires a specialized parser.
How can I create my own .puz files?
You generally cannot create these manually; you need crossword construction software. Programs like CrossFire or Crossword Compiler allow you to build a grid and write clues, then export the final project as a .puz file for others to solve.
What is the MIME type for .puz files?
There is no official standard registered with IANA, so web servers often treat them as generic binary data using application/octet-stream. Some implementations may use unofficial types like application/x-crossword. For more on binary handling, check mime-type.com.
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.
