About .chr Files
CHR files are binary files used to store graphical character set data, often for applications like game development or font design.
- Main use: Storing a set of pixel-based glyphs or tiles for graphic projects.
- Other uses: Encoding custom icons, fonts, or sprite graphics within certain software.
- Technical details: The MIME type is application/octet-stream, meaning the file holds binary data rather than plain text.
- Software/apps: Specialized graphic editors, charset editors, or dedicated game development tools are required to properly open, view, or edit these files.
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 .chr file?
A .chr file is typically a Character Set file used to store graphical data such as fonts, sprites, or game tiles. These are binary files commonly associated with retro game development (like NES homebrew) or legacy programming environments like Borland Turbo C.
How do I open a .chr file used in game development?
To view or edit character sets for retro consoles (like the NES or Game Boy), you need specialized tile editors. Popular tools include YY-CHR and Tile Molester, which decode the binary data into visible pixel grids.
Can I open a .chr file in Notepad?
No, .chr files contain compiled binary data, not human-readable text. Opening one in a text editor will result in garbled characters because the file is treated as application/octet-stream rather than plain text.
How can I convert a .chr file to an image like PNG?
You cannot convert a .chr file simply by renaming it. You must open the file in a utility like YY-CHR, which renders the binary data as graphics, and then use the tool's export function to save the sprite sheet as a BMP or PNG image.
Why won't my .chr file open in a tile editor?
The .chr extension is ambiguous and used by multiple programs. If a tile editor won't open it, the file might be a 3ds Max Character file (used for 3D animation rigs) or a legacy Borland BGI font, which requires different software such as Autodesk 3ds Max.
What is the correct MIME type for .chr files?
There is no standard registered MIME type for proprietary character set files. When serving these files over a network, they are usually configured as the generic binary type application/octet-stream to force a download.
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.
