The fastest way to duplicate a layer in Photoshop CS5 is to select the layer in the Layers panel and press Ctrl + J (Command + J on a Mac). You can also right-click the layer and choose Duplicate Layer, go to Layer > Duplicate Layer, or drag the layer onto the Create a new layer icon at the bottom of the panel. The copy appears directly above the original with “copy” added to its name.
These methods work the same way in every version since CS5, including current versions of Photoshop. Below you’ll also learn how to duplicate several layers, copy a layer to another document, and duplicate part of a layer.

How to duplicate a layer with the menu
- In the Layers panel, click the layer you want to copy. If the panel is hidden, press F7 or choose Window > Layers.
- Right-click the layer name (not the thumbnail) and choose Duplicate Layer.
- In the dialog box, type a name in the As box.
- Leave Document set to the current file, and click OK.
How to duplicate a layer with the Move tool
- Select the layer and press V for the Move tool.
- Hold Alt (Option on Mac) and drag on the canvas. The pointer shows a double arrow.
- Release the mouse. The copy lands where you dropped it. Add Shift while dragging to keep it in a straight line.
How to duplicate multiple layers
Hold Ctrl (Command on Mac) and click each layer, or click the first and Shift-click the last to select a range. Then press Ctrl + J or choose Layer > Duplicate Layers. To copy a whole group, select the group folder and duplicate it the same way.
How to copy a layer to another document
- Use the dialog: Right-click the layer, choose Duplicate Layer, and pick the other open file from the Document menu. Choose New to put the layer in a brand-new file.
- Drag it: Arrange the windows side by side, then drag the layer from the Layers panel onto the other image.
How to duplicate just part of a layer
- Make a selection with the Marquee, Lasso, or Quick Selection tool.
- Press Ctrl + J to copy the selected area to a new layer (Layer via Copy).
- Press Shift + Ctrl + J instead to cut it to a new layer and leave a hole in the original (Layer via Cut).
Why can’t I duplicate a layer?
- No layer is selected. Click the layer name so it’s highlighted.
- You’re editing text. Press Esc or click the check mark in the options bar to finish editing first.
- The Background layer is locked. You can still duplicate it. The copy is a normal layer you can edit freely.
- A selection is active. Ctrl + J copies only the selection. Press Ctrl + D to deselect, then try again.
Frequently asked questions
What does duplicating a layer do?
It creates an identical copy, including layer styles and masks, so you can experiment without changing the original.
Why duplicate the Background layer?
It’s a common first step before retouching. You edit the copy and keep the original untouched in case you need to start over.
Does duplicating a layer increase file size?
Yes. Each layer adds to the file size. Delete copies you don’t need, or merge layers when you’re done.
