How to Merge Layers in Photoshop: Basic and Advanced Techniques
In Photoshop, layers are the building blocks of any project. As your design grows, you might end up with many layers on your canvas. According to Adobe's official data, professional designers average 57 layers per PSD file.
Too many layers can make things confusing and increase your file size. Merging layers helps keep your workflow simple and makes Photoshop run faster.
In this tutorial, we would like to share how to merge layers in Photoshop, taking you from beginner to expert.

The Basics of Merging Layers in Photoshop
In Photoshop, every layer is like a clear sheet you can edit independently. Once you finish editing a part of your work, you can merge several layers into one. This not only makes your file smaller but also makes future edits easier.
When you merge layers, the top layer covers the area of the layer beneath it. Even if one layer has transparent parts, that transparency stays after merging.
Remember, merging layers is a one-way process. After you save, you can't get the original layers back. It's best to save a copy of your file or back up your layers before merging, or only merge them when you're sure you won't need to make any more changes.
How to Merge Layers in Photoshop?
Photoshop offers several ways to merge layers. Here are some common ways:
1. Merge Down
This method merges the selected layer with the one right below it. First, click the top layer you want to merge. Then, right-click and choose "Merge Down" from the menu, or press "Ctrl + E" ("Cmd + E" on macOS).
2. Merge Visible Layers
If you only want to merge the layers you see on the canvas, hide the ones you don't need by clicking the eye icon in the Layers panel.
Then, right-click on any visible layer and select "Merge Visible" from the menu, or press "Shift + Ctrl + E" ("Shift + Cmd + E" on macOS).
3. Merge Selected Layers
If you need to merge several layers that are not next to each other, hold down Ctrl (or Cmd on macOS) in the Layers panel and click on each layer you want to merge.
Alternatively, to select a group of consecutive layers, click the first layer, hold down Shift, and then click the last layer. This will select all the layers in between.
For example, if you want to merge two layers in Photoshop, just select them in the Layers panel, right-click, and choose "Merge Layers" from the menu.
4. Flatten Image
If you want to know how to merge all layers in Photoshop, the Flatten Image command is exactly what you need.
This command combines all the layers in Photoshop into one single layer. When you use it, all visible layers are merged together, and any hidden layers are removed.
This not only makes your file smaller but also simplifies its structure, making it easier to print or export.
To use this command, click "Layer" in the top menu and then choose "Flatten Image" from the drop-down menu.
Keep in mind that after flattening, you cannot edit the layers separately. It's a good idea to save a copy of your file with all layers intact before you flatten the image.
5. Stamp Visible Layers
Stamp Visible is a unique way to merge layers without changing the original ones. It combines the images from several layers into a new layer while leaving the originals intact.
If you want to see a merged effect but keep the original layers, Stamp Visible is the best option.
Stamp Down a Layer:
Select a layer and press "Ctrl + Alt + E" ("Cmd + Option + E" on macOS). This stamps the content of that layer onto the one below it without altering the original.
Stamp Multiple Layers:
Select the layers you want and press "Ctrl + Alt + E" ("Cmd + Option + E" on macOS). This creates a new layer with the combined content while keeping the original layers the same.
Stamp Visible Layers:
Press "Shift + Ctrl + Alt + E" ("Shift + Cmd + Option + E" on macOS) to stamp all the layers you can see into one new layer. The original layers stay unchanged.
Stamp a Layer Group:
Select a layer group and press "Ctrl + Alt + E" ("Cmd + Option + E" on macOS). This stamps all layers in the group into a new layer while leaving the group intact.
Extra Tip:
Merging layers reduces the number of layers, but stamping often adds a new layer. Stamp Visible is great for image compositing because it keeps your original layers.
It is also useful for creating special effects, especially when used with layer masks to build up multiple effects.
As you can see, whether you're merging layers or stamping layers, there are all kinds of shortcuts. Using them can definitely boost your productivity, but remembering every shortcut isn't easy.
We want to recommend the TourBox creative console. You can map your most-used Photoshop shortcuts to the TourBox, and with just one hand you can operate it, just like using a game controller, to perform many tedious tasks with ease.
And the magic of TourBox doesn't stop there. If you're interested in learning more, click the link above for more details.
Detailed Steps for Merging Layers in Photoshop
Here is a simple example to show you how to merge layers. The steps are clear and easy to follow:
Step 1: Open Your File and Check the Layers
- Start Photoshop and open your file.
- Look at the layer names and order in the Layers panel. Make sure you know what each layer does.
- If needed, rename the layers to make them easier to identify.
Step 2: Choose the Layers to Merge
- For consecutive layers: Click the current layer and press "Ctrl/Cmd + E" to merge it with the layer below.
- For non-consecutive layers: Hold down Ctrl (Cmd on macOS) and click each layer you want to merge. Then, right-click and select "Merge Layers."
Tip: When you select multiple layers, they will be highlighted in the panel. This makes it clear which layers you have chosen.
Step 3: Merge the Layers
- To merge down: Right-click and choose "Merge Down" to combine the current layer with the one below.
- To merge visible layers: Hide any layers you do not want to merge. Then, press "Shift + Ctrl + E" ("Shift + Cmd + E" on macOS).
- To keep your original layers and create a merged copy: Use the Stamp Visible command by pressing "Alt + Ctrl + E" ("Option + Cmd + E" on macOS). This adds a new layer with the merged content while leaving the original layers unchanged.
Things to Remember:
Merging is irreversible. It's a good idea to duplicate the layers (Ctrl/Cmd + J) or save your PSD file before merging.
Advanced Tips for Merging Layers in Photoshop
- Using Clipping Masks: If you need some layers to show in a specific shape, first create a clipping mask. Then merge the layers to keep the look you want.
- Organize Your Layers: Before merging, group similar or related layers together. Then merge the groups to keep your Layers panel neat.
- Use Keyboard Shortcuts for Speed: Learning shortcuts can save you time and make editing easier. A TourBox can boost your efficiency even more. If you work on an iPad, check out our TourBox Elite Plus.
Layer merging is a basic yet essential skill in Photoshop. It might seem simple, but it's a key part of managing your layers. Good layer management not only boosts your productivity but also makes your creative work run more smoothly.
We hope this short tutorial gives you a clear understanding of the basic concepts, step-by-step instructions, and handy tips for merging layers in Photoshop, so you can use them in your projects.
