Crop, flip, and rotate photos

In Pixelmator Photo, you can crop a photo to improve its composition, remove unwanted parts, or use the machine learning-trained ML Crop to automatically crop the image for you.

You can also rotate and flip a photo, use one of the available crop presets, or crop it to a custom aspect ratio. In the list of presets at the bottom of the screen, you can add new custom presets or remove the ones you no longer use.

Crop a photo

Crop photos automatically

When you turn the Crop tool on, you can grab one of the crop box handles and start resizing it yourself or use ML Crop to crop an image automatically. ML Crop has been trained on millions of photos to recognize good and bad image compositions. Based on this training, ML Crop can analyze and crop images almost as intuitively as a skilled photographer would.

    • Tap in the toolbar at the top of the screen.
    • Press C on your keyboard.
  2. If a different crop mode is selected, tap the crop mode button in the bottom-left corner of the screen, and choose Crop.

  3. Tap ML Crop at the bottom of the screen.

You can also use ML Crop in combination with the crop presets. ML Crop will find the best way to apply the specific preset and carefully calculate what to keep and what to leave out of the image.

  1. Choose the Crop tool by doing one of the following:

    • Tap in the toolbar at the top of the screen.
    • Press C on your keyboard.

Note: For the images that have already been cropped, ML Crop uses the current aspect ratio as a starting point for cropping.
