How to merge layers in Photoshop

For most purposes, the best option is a keyboard shortcut:

• Click on one of the layers you want to merge in the Layers panel.
• Hold Shift, then click on all of the other layers you’re merging.
• To merge, hit Control-E in Windows, or Command-E on a Mac.

If you want to accomplish the same thing via menus, select the layers you want to merge using the Shift-click method, then go to Layers > Merge Layers.

How to merge visible layers in Photoshop

Should it make sense for your work, you can choose to merge all visible layers, rather than pick layers one-by-one.

• Toggle the eye icons in the Layers panel to control visibility.
• When all the layers you want to merge have an eye icon next to them, go to Layers > Merge Visible in the top menu.

How to merge layers in Photoshop by flattening an image

Be extra careful about using this method, since “flattening” merges all visible layers into a background. If you don’t want to replace your existing background, it’s better to use other options.

• Toggle the eye icons in the Layers panel to control visibility.
• When all the layers you want to merge have an eye icon next to them, go to Layers > Flatten Image in the top menu.
