Fit several Preview images or inspect their actual size

Option-Command-9 fits all images in the window; Option-Command-0 shows them at actual size. These are view changes, not file resizing.

Scope
Preview · Current vendor documentation checked 3 November 2026; no running-app compatibility test is claimed.
Keyboard and customization
Documented Mac defaults; punctuation and function keys depend on keyboard layout and hardware.. User bindings, app versions, focused controls and installed extensions can change a command. Inspect the active app menu or its shortcut editor when a listed combination differs.
Review basis
Documentation reviewed 2026-11-03 by Codex — primary-documentation and editorial review; no hands-on runtime test. These bindings were not tested in a running app for this guide.

Separate the image file from its display scale

An image can look small because it is being fitted into a window, not because its stored pixel dimensions changed. Conversely, actual-size viewing can make a large image extend beyond the visible area. Choose the view that answers your current question before considering an edit to the file itself.

Use consistent viewing across a set

When several images are open together, applying the same fitting or scale command makes comparison more predictable. A fitted view is useful for overall composition, while actual size helps inspect detail. Neither alone proves how the image will appear when printed or displayed on a device with different dimensions.

Return to an overview before choosing another image

After inspecting a detail at a larger scale, fit the images again so you can recognise which item is selected. Work with copies when practising any actual edits. The commands in this table change the view, but neighbouring editing commands in the same application may modify the image.
