What is an SFZ File?

Question: What is an SFZ File?

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

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

Answer: A file with the SFZ file extension is a SoundFont Compressed file.

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

How To Open an SFZ File:

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

SFZ files can be opened with Cakewalk's free SFZ Player program.

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

Tip: Use Notepad or another text editor to open the SFZ file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This may or may not be the case with SFZ files but it's worth a try.

If you find that an application on your PC does try to open the SFZ file but it's the wrong application or if you would rather have another installed program open SFZ 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 SFZ File:

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

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

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