Do I need to maximize my compatibility?

Adobe Photoshop CS/CS2

Operating Systems:

Macintosh, Microsoft Windows


Photoshop, Maximize Compatibility, Preferences


Every time I save a Photoshop file I get a warning asking me if I want to maximize my compatibility. Is this something I need to do? Can I turn this warning off, or should I leave it on?


The Maximize compatibility option is actually a preference setting, and yes, you can turn it on or off via the Preferences dialog box. To access the preference, choose Photoshop > Preferences > File Handling (Edit > Preferences > File Handling in Windows) and check out the File Compatibility section of the dialog box, where you’ll find a pop-up menu for Maximize PSD File Compatibility. Your options are Always, Never, and Ask.


Note: In previous versions this warning was still there, it was just called something different. It ranged from version to version but one example was “Maximize Backwards Compatibility in Photoshop Format.”


What does it do?

So what does the maximize compatibility option do? In a nutshell, it saves a composite (flattened) version of your layered file, along with the layered file when you save the document. In doing so, you wind up with a larger file size. As we mentioned before, there are three options to choose from in the pop-up menu.

        Always. When you select this option, you won’t get a prompt— Photoshop will always save a composite copy of your image with the layered file.
