How to Merge Layers in Photoshop Without Flattening Your Image
Need to merge layers in Photoshop? Don't flatten the image and lose all your work. Learn how to merge a copy of your existing layers onto a separate layer! For Photoshop CC and earlier.
Written by Steve Patterson.
When working with multi-layered Photoshop documents, you often reach a point where you need to flatten the image. Usually it's so you can sharpen the image for print or for uploading to the web. Or you may want to move the image to another layout or design.
But while Photoshop does have a Flatten Image command, it's not the solution you're looking for. When you flatten the image, you lose all of your layers. And if you save and then close the document after flattening the image, those layers are lost forever.
So in this tutorial, I'll show you a better way, one that's entirely non-destructive. You'll learn how to merge your layers onto a separate layer and keep your existing layers intact!
But there's a trick. You won't find a "Merge All Layers To A New Layer" command anywhere in Photoshop. Instead, you need to know a secret keyboard shortcut. And while not everyone is a fan of keyboard shortcuts, I think you'll agree that this one is definitely worth knowing.
Let's get started!

Why you should not flatten a Photoshop document
Before we learn how to merge layers onto a new layer, let's take a quick look at why flattening an image is a bad idea. I'm using Photoshop CC but you can follow along with any recent version.
In the Layers panel, we see that I've added several layers to my document. Along with the original image on the Background layer, I also have a separate layer for smoothing skin. Above that is a layer for whitening teeth. And at the top is a layer for changing eye color:

If I was done working on the image, I might want to print it, email it, or upload it to the web. But first, I would want to sharpen the image. And before I could sharpen it, I would need to merge all of my layers onto a single layer.
The problem with flattening the image
One way to merge layers in Photoshop is to simply flatten the image. And I could do that by going up to the Layer menu in the Menu Bar and choosing the Flatten Image command:
Going to Layer > Flatten Image.
But here's the problem. By flattening the image, I've lost all of my layers. And if I save and close the document at this point, my layers will be gone for good, along with my ability to edit any of those layers in the future:
The result after flattening the image.
I'll undo that and restore my layers by going up to the Edit menu and choosing Undo Flatten Image:
Going to Edit > Undo Flatten Image.
How to merge layers onto a new layer
Here's a better way to work. Rather than flattening the image, we can keep our existing layers and just merge a copy of them onto a brand new layer!
Step 1: Select the top layer in the Layers panel
Whenever we add a new layer, Photoshop places it directly above the currently-selected layer. So since you'll most likely want the merged copy to appear above your existing layers, start by selecting the top layer in the Layers panel:
Clicking the top layer to select it.
Step 2: Merge a copy of the layers onto a new layer
Then use the secret keyboard shortcut to merge a copy of your layers onto a new layer.
On a Windows PC, press Shift+Ctrl+Alt+E. On a Mac, press Shift+Command+Option+E. Basically, it's all three modifier keys, plus the letter E.
And if we look again in my Layers panel, we now see a brand new layer above the original layers. This new layer holds a merged copy of all the other layers in the document:
Photoshop adds a new layer and merges a copy of the existing layers onto it.
Step 3: Rename the new layer "Merged"
At this point, it's a good idea to give the merged layer a more descriptive name. Double-click on the existing name (in my case, it's "Layer 1"), rename the layer "Merged", and then press Enter (Win) / Return (Mac) on your keyboard to accept it:
Renaming the merged layer.
And there we have it! That's how easy it is to avoid flattening your image by merging your layers onto a new layer in Photoshop!
