Crop and straighten photos in Photos on Mac
You can crop a photo to improve its composition or eliminate unwanted parts of the image. You can crop it to a preset or custom aspect ratio, or you can constrain the photo to its original aspect ratio. You can also straighten photos that were taken at an angle unintentionally.
Note: You can also crop and straighten videos. See Change and enhance a video.
Important: Cropping a photo changes its appearance everywhere in Photos, including in albums, slideshows, and projects. To edit a photo without changing it everywhere, first duplicate the photo and then edit the duplicate.
In the Photos app on your Mac, double-click the photo, then click Edit in the toolbar.
Click Crop in the toolbar.
Tip: To quickly see the crop and straighten tools while editing, press C.
Do any of the following:
Crop or straighten the photo automatically: Click Auto.
Crop manually: Drag the selection rectangle to enclose the area you want to keep in the photo.
Crop to specific proportions: Click the aspect ratio you want in the sidebar.
For example, for a square photo, choose Square. For printing the photo, choose one of the preset aspect ratios, such as 8:10. To resize a photo for use in a high-definition video, choose 16:9. Or choose Custom to enter a custom aspect ratio for a photo.
Flip the image: Click Flip to flip the image horizontally. Option-click to flip the image vertically.
Straighten the photo: Drag the Straighten, Vertical, or Horizontal slider to adjust the angle of the photo. Or move the pointer outside of the selection rectangle, then use the rotation arrow to adjust the angle of the photo.
Remove the current cropping or straightening changes: Click Reset.
When finished making changes, do one of the following:
Save your changes: Click Done.
Stop cropping without saving your changes: Click Revert to Original.
