About .kvk Files
KVK files are Keyman Virtual Keyboard files. They store keyboard layout data in a binary format.
These files let you define custom keyboard mappings for non-standard input. Their MIME type is application/octet-stream, meaning they are treated as a generic binary file by systems.
- Main use case: Configuring virtual keyboards for multilingual and custom input.
- MIME type: Uses a binary data stream format.
- Software: Typically used with the Keyman software suite, which can open, view, and edit these files.
- Utility: Helps adapt computer input to special language needs.
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 .kvk file and what is it used for?
A .kvk file is a Keyman Virtual Keyboard file used by the Keyman input software. It stores the binary data required to display an On-Screen Keyboard (OSK), allowing users to see a visual map of where characters are located on their physical keyboard layout.
How do I open or edit a .kvk file?
You cannot open a .kvk file with a standard text editor because it is in a binary format. To edit the visual keyboard layout, you should use Keyman Developer, which allows you to modify the source .kvks (XML) file and then compile it into the binary .kvk format for distribution.
Why does the .kvk file look like gibberish in Notepad?
The .kvk file contains compiled binary data, not human-readable text. Because its MIME type is often treated as application/octet-stream, text editors attempt to decode the binary bytes as text, resulting in garbled characters. You must use specific software like Keyman Developer to view it correctly.
What is the difference between .kvk and .kmx files?
The .kmx file contains the compiled rules for processing keystrokes (the logic), while the .kvk file contains the visual layout for the On-Screen Keyboard (the display). Both files are often packaged together inside a .kmp (Keyman Package) file to provide a complete keyboard experience.
Can I convert a .kvk file back to an XML format?
Direct conversion from .kvk back to a readable format is not a standard feature for end-users. Ideally, you should locate the original .kvks source file, which is XML-based and editable. If you only have the binary .kvk, you are generally limited to using it within Keyman Desktop.
How should I configure my server to host .kvk files?
If you are hosting Keyman keyboards for download, you should configure your web server to serve .kvk files with the MIME type application/octet-stream. You can verify generic binary MIME settings at 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.
