Steps

Step 1: Open the Image in Preview

The first step in cropping a jpeg on a Mac is to open the image in Preview. Preview is the default image viewer on Macs, and can be accessed by double-clicking on the image file in Finder, or by right-clicking on the image file and selecting “Open With -> Preview”. Once the image is opened in Preview, you should see it displayed on your screen.

Tips: You can use the keyboard shortcut “Command + O” to quickly open an image in Preview. You can also drag and drop an image file directly into the Preview icon on your dock to open it.

Step 2: Select the Crop Tool

Next, select the crop tool by clicking on the “Tools” icon in the top toolbar, and then selecting the “Crop” option from the dropdown menu. Alternatively, you can use the keyboard shortcut “Command + K” to select the crop tool directly. When you select the crop tool, you should see a set of grid lines appear over your image.

Tips: You can adjust the size and shape of the crop tool by dragging the corners or edges of the grid lines.

Step 3: Adjust the Crop Tool Position and Size

Position the crop tool over the part of the image you want to keep. You can adjust the size and position of the crop tool by clicking and dragging on the edges and corners of the grid lines. Once you’re happy with the position and size of the crop tool, click and drag the entire tool over the portion of the image you want to keep.

Tips: You can hold down the “Shift” key while dragging the edges of the crop tool to maintain the aspect ratio. You can also hold down the “Option” key while dragging to resize the crop tool from the center.

Step 4: Crop the Image

When you have the crop tool positioned correctly, you can crop the image by clicking on the “Crop” button in the top toolbar, or by using the keyboard shortcut “Command + K”. After cropping, only the part of the image inside the crop tool will remain, and the rest will be removed.

Tips: You can use the “Undo” keyboard shortcut “Command + Z” to undo the crop if you make a mistake.

Step 5: Adjust the Crop If Necessary

If you’re not happy with the results of your crop, you can adjust it by clicking on the crop tool again and moving the grid lines. Once you’ve made the necessary adjustments, crop the image again by clicking on the “Crop” button.

Tips: You can use the arrow keys on your keyboard to nudge the crop tool into the desired position.

Step 6: Save Your Cropped Image

Once you’re happy with the crop, save your image by clicking on “File” in the top toolbar, and selecting “Save” (or “Save As” if you want to save it under a different name). Your new cropped image will now be saved on your computer.

Tips: You can use the keyboard shortcut “Command + S” to quickly save your cropped image.

Step 7: Undo Your Crop if Needed

If you realize later on that you want to undo your crop, you can simply revert back to the original image. To do this, open your cropped image in Preview and click on “File” in the top toolbar. Select “Revert to” and then “Original”. This will replace your cropped image with the original, un-cropped version.

Tips: You can also use the “Versions” feature in Preview to save different versions of your image, so you can easily switch between them if needed.

Step 8: Use the Crop and Resize Dialog Box

If you want to crop and resize your image at the same time, you can use the crop and resize dialog box. To access this dialog box, select “Tools” from the top toolbar, and then “Adjust Size”. In the dialog box, you can enter the new dimensions for your image and then crop it using the grid lines that appear.

Tips: You can use the keyboard shortcut “Command + Option + I” to quickly open the adjust size dialog box.

Step 9: Use the Aspect Ratio Feature

When cropping an image, you can also use the aspect ratio feature to maintain the same proportions of your image. To activate this feature, click on the “Tools” icon in the top toolbar, select “Crop”, and then choose “Original Ratio” or “Custom Ratio” from the dropdown menu.

Tips: You can also use the “Constrain Proportions” checkbox in the adjust size dialog box to maintain the aspect ratio when resizing your image.

Step 10: Use the Ratios Preset Feature

Preview also features a set of preset ratios that you can use when cropping an image. To access these ratios, click on the “Tools” icon in the top toolbar, select “Crop”, and then choose the desired preset ratio from the dropdown menu.

Tips: You can also create your own custom ratios by selecting “Custom Ratio” from the dropdown menu, and entering your desired dimensions in the fields provided.

Step 11: Use the Alignment Feature

The alignment feature allows you to align your crop tool with specific areas of the image. To activate this feature, click on the “Tools” icon in the top toolbar, select “Crop”, and then choose the desired alignment option from the dropdown menu.

Tips: You can also use the “Align To” dropdown menu in the adjust size dialog box to align your image with specific edges or corners of the canvas.

Step 12: Use the Grid Feature

The grid feature provides a visual guide for aligning your crop tool with certain elements of the image. To activate this feature, click on “View” in the top toolbar, select “Show Grid”, and then adjust the grid settings as desired.

Tips: You can also use the “Snap to” option in the grid settings to snap your crop tool to the grid lines for more precise alignment.
