How to Mirror an Image in Photoshop

Step 1: Open your image

Start by opening your image into Photoshop. I’ll use this image from Adobe Stock:

For help with opening images, see my Getting Images into Photoshop complete guide.

Step 2: Duplicate the document

Before we mirror the image, let’s make a copy of our Photoshop document. That way, we won’t accidentally save the mirrored version over the original.

Go up to the Image menu in the Menu Bar along the top of the screen and choose Duplicate:

Going to Image > Duplicate.

Then in the Duplicate Image dialog box, name the copy “Mirror” and click OK:

Naming the copy of the document.

And if we look at the document tabs just below the Options Bar, we see that we’re now working on a copy of the image named “Mirror”:

The document tabs.

You can close the original document by clicking the small “x” in its tab. On a Windows PC, the “x” is found on the right side of the tab, and on a Mac, it’s on the left:

Step 3: Select the Crop Tool

Next, select the Crop Tool from the toolbar:

Selecting the Crop Tool.

Step 4: Set the aspect ratio to Ratio

And in the Options Bar, make sure that the Crop Tool’s Aspect Ratio is set to Ratio. This will let us freely adjust the sides of the cropping border:

Step 5: Drag one side of the cropping border to the flip point

Depending on which direction your image needs to flip, click on the left or right side of the cropping border and drag it over to the spot where the image will be mirrored.

In my case, I want to flip the image from left to right using the woman’s hair as the mirror point. So I’ll drag the right side of the cropping border to that location:

Step 6: Drag the opposite side to crop away unwanted space

I also don’t need all of that empty space on the left of the image. So to crop some of it away, I’ll drag the left side of the cropping border inward:

Step 7: Turn on “Delete Cropped Pixels”

Before you crop the image, go up to the Options Bar and make sure Delete Cropped Pixels is checked:

The Delete Cropped Pixels option.

Step 8: Crop the image

Then still in the Options Bar, crop the image by clicking the checkmark:

Clicking the checkmark.

And here’s my result after cropping the photo:

Step 9: Duplicate the Background layer

In the Layers panel, the image sits on the Background layer.

Make a copy of the Background layer by dragging it down onto the Add New Layer icon:

Duplicating the Background layer.

The copy appears above the original:

The “Background copy” layer.

Step 10: Select the Free Transform command

With the “Background copy” layer selected, go up to the Edit menu in the Menu Bar and choose Free Transform. Or press Ctrl+T (Win) / Command+T (Mac) on your keyboard:

Going to Edit > Free Transform.

Step 11: Drag the reference point onto the side handle

Photoshop’s Free Transform box and handles appear around the image.

And in the center of the transform box is a target icon known as the reference point. This point marks the center of the transformation:

How to show the reference point

If you are using a newer version of Photoshop and the reference point is missing, go up to the Options Bar and click inside the Toggle Reference Point checkbox:

The Toggle Reference Point checkbox.

Then click on the reference point and drag it onto the handle on the side where the image will flip.

Since my image is going to flip from left to right, I’ll drag the reference point onto the right side handle:

Dragging the reference point onto the side handle.

Step 12: Choose the Flip Horizontal command

Then with the Free Transform command still active, right-click (Win) / Control-click anywhere inside the image and choose Flip Horizontal from the menu:

Choosing the Flip Horizontal command.

It won’t look like the image has flipped. Instead, the Free Transform box will move to the empty area beside the image:

Step 13: Accept and close Free Transform

Commit the transformation and close Free Transform by clicking the checkmark in the Options Bar:

Clicking the checkmark.

Step 14: Select the Reveal All command

If the cropping border is still visible around your image, it’s because the Crop Tool is still active. Press the letter M on your keyboard to quickly switch to the Rectangular Marquee Tool to remove the border.

At this point, we’ve created the mirrored version of the image, but we can’t see it because the mirrored half is sitting off to the side. So here’s the fun part. To view the entire effect, go up to the Image menu in the Menu Bar and choose Reveal All:

Going to Image > Reveal All.

The Reveal All command instantly reveals the entire Photoshop canvas, including the hidden areas, giving us our final result.

To fit the entire effect on the screen, choose the Fit on Screen command by pressing Ctrl+0 (Win) / Command+0 (Mac) on your keyboard:
