What is an HQX File?

Question: What is an HQX File?

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

Before you can open an HQX 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 .HQX file extension refers to.

Answer: A file with the HQX file extension is a Macintosh BinHex 4 Compressed Archive file.

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

How To Open an HQX File:

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

HQX files are typically seen in Macintosh systems but if you're running Windows and need to decompress an HQX file, try WinZip, 7-Zip, ADL UNCOMPRESSOR or another popular Windows compression application.

If you know anything else useful about HQX files, please let me know so I can update this page.

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

How To Convert an HQX File:

There are two main ways to attempt to convert an HQX file to another file type:

The first option involving opening the HQX 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 HQX files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the HQX 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.
