How to view and recover previous versions of images and PDFs in Preview

Preview Browse Previous Versions on Mac

As you probably know, Preview on Mac automatically saves changes you make to an image or PDF file. While most times this is benefit, it can also be a detriment. You can create a duplicate before you start working on the file, but if you forget, then you’ve just changed the original. And this isn’t always what you want.

At the same time, you may make several changes that you decide you don’t want to use after all. But again, you’ve changed and saved the file already.

Here, we’ll show you how to view and recover previous versions of PDFs and images in Preview. This allows you to go back and grab an earlier version to use or copy.
