Can’t crop images with Preview on Mac?

Some Mac users can’t find the Crop option or when they go to the Tools menu, the Crop option is greyed out. You have to select the area on the image to crop, otherwise you can’t select Crop under the Tools menu.

If you can’t see the selection tools, you need to click the Show Markup Toolbar button at the toolbar or click to open the View menu from the Apple top menu bar, then choose Show Markup Toolbar from the drop down menu.

If you can’t see the Toolbar in Preview, click the View menu, choose Show Toolbar option.

No “Save As” option in Preview?

There is no “Save As” option in the File menu and the Save option just saves the changes to the original image. If you do’t want to lose the original version, choose File > Export, then choose a new name, location or format to save it as a new image file on your Mac.
