When browsing files in the Finder, you have the option for previewing them using Apple’s QuickLook feature. This allows you to either see some general information about files such as file size and last modification date, but for supported files you should see a preview of their contents, simply by pressing the Space bar with a file selected. While convenient, for previewing a file or two, you can use QuickLook to zoom in on images, as well as open files you are previewing.
When you quicklook an image, you should see the entire image show in the QuickLook window, so large images will be scaled to fit. However, you can zoom in on the image using a couple of methods:
- Pinch Zoom — Apple’s pinch-zoom gesture for its trackpads can be used to zoom to practically any level on a quicklook image.
- Option key — By pressing and holding the Option key, you will zoom in to the image’s full size.
Do you have any quick QuickLook tips? If so, share them below in the comments!
Snow Leopard users:
– use OPT-mouse click to zoom in, SHF-OPT-mouse click to zoom out
– use CMD-OPT-mouse click to toggle the zoom between actual size and scaled size
– while zoomed, the screen pointer should change to a cross with an arrowhead on the end of each arm, to signify you can drag the image around inside the viewing window; no scroll bars, just drag it. Mavericks does similar, but with scrollbars and an unchanged pointer: you can both drag and scroll in Mavericks
