Question: What is a CRX File?

Did you find a CRX file on your computer and wonder what program should open it? Maybe someone emailed you a CRX file but you're not sure how to use it. Perhaps you tried to open the CRX file but Windows told you that it could not open it.

Before you can open a CRX file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .CRX file extension refers to.

Answer: A file with the CRX file extension is a Google Chrome Browser Extension Archive file.

Some CRX files might also be Links Games Course files.

Other types of files may also use the CRX file extension. If you know of any additional file formats that use the .CRX extension, please let me know so I can update this information.

How To Open an CRX File

The easiest way to open a CRX file is to double-click on it and let your PC decide which default application should open the file. If no program opens the CRX file then you probably don't have an application installed that can view and/or edit CRX files.

Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.

The Google Chrome browser uses CRX files to provide extendability in the browser. A Google Chrome CRX file is actually just a renamed ZIP file so any archive/compression program, like PeaZip or 7-Zip (both free), will open CRX files for expansion.

If you know of any more programs that open CRX files, please send me a quick email and let me know the name of the program so I can update this page.

If you find that an application on your PC does try to open the CRX file but it's the wrong application or if you would rather have another installed program open CRX files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert a CRX File

There are two main ways to attempt to convert a CRX file to another file type:

The first option involving opening the CRX file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens CRX files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the CRX file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
