About .pgn Files
PGN files are text files that store chess game records in a Portable Game Notation format.
They are marked with MIME types such as application/x-chess-pgn and application/vnd.chess-pgn to indicate their content to software and systems.
- Chess Game Recording: They list moves, game events, and annotations.
- Metadata Storage: They include details like player names, dates, event info, and game outcome.
- Software Compatibility: Programs such as ChessBase, Arena, Scid, and even plain text editors can open them.
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
How do I open a PGN file on my computer?
You can open PGN files using specialized chess software such as ChessBase, Scid vs. PC, or Arena Chess GUI. Because the format is plain text, you can also view the raw move data using any simple text editor like Notepad or TextEdit.
Can I edit a PGN file manually?
Yes, PGN files are human-readable text files. You can open them in a text editor to correct player names, dates, or move notation, but you must strictly adhere to the Portable Game Notation standard to ensure chess engines can still read the file.
What is the difference between PGN and FEN files?
A PGN file records the entire history of a chess game, including every move and metadata like player names. In contrast, a FEN (Forsyth-Edwards Notation) string only describes the arrangement of pieces on the board at a single specific moment in time.
How can I convert a PGN file to a PDF?
Most chess database software allows you to print a game or export it directly to PDF, often including diagrams of key positions. There are also various online tools where you can paste the PGN text to generate a printable document.
What MIME type should be used for PGN files on a server?
To ensure browsers and applications handle the file correctly, servers should use the MIME type application/x-chess-pgn or application/vnd.chess-pgn. You can find more technical details about these types on mime-type.com.
Why is my PGN file not loading in my chess app?
This usually happens if the file contains syntax errors, such as broken header tags (e.g., missing brackets []) or invalid move notation. Opening the file in a text editor to look for formatting inconsistencies or using a tool like pgn-extract can help resolve these issues.
Can I view PGN files on Android or iPhone?
Yes, mobile apps like Lichess, Chess.com, and Analyze This allow you to import PGN files. You can typically open the file directly from your email or file manager, or paste the text content into the app's analysis board.
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.
