As your design project grows, your Layers panel can quickly become chaotic. Merging layers is critical for organizing your workspace, applying global effects, and optimizing your final file size.
Merging combines specific selected layers into one, while flattening compresses the entire document into a single background layer, destroying all transparency.
Methods for Combining Layers
Follow these exact steps to execute the operation flawlessly.
1
Merge Down
Select a layer and press Ctrl + E (Windows) or Cmd + E (Mac). This merges the selected layer with the one directly below it.
2
Merge Selected Layers
Hold Shift or Ctrl/Cmd to select multiple specific layers. Right-click and choose Merge Layers (or press Ctrl/Cmd + E). Only the selected layers will be combined.
3
Merge Visible
Hide any layers you want to keep separate by clicking the eye icon. Then press Shift + Ctrl + E (Windows) or Shift + Cmd + E (Mac) to merge all currently visible layers into one.
4
Flatten Image
Go to Layer > Flatten Image. Use this only when you are completely finished, as it permanently flattens everything and removes alpha transparency.

Need to quickly merge elements but don't have access to your Photoshop desktop app? PhotoQuill supports full layer management. Open your PSD file directly in the browser, select your layers, and hit Ctrl+E. It’s 100% free, private, and processes instantly without uploading your files.
What is the shortcut to merge all layers in Photoshop?
The shortcut to flatten all layers into one is Ctrl + Shift + E (Windows) or Cmd + Shift + E (Mac). This merges all visible layers into the bottom-most layer.
What is the difference between Merge Layers and Flatten Image?
Merge Layers (Ctrl+E) only merges the layers you have selected. Flatten Image merges ALL layers, including hidden ones, producing a single background layer with no transparency.
Can I merge layers without losing quality?
Merging raster layers is destructive. To preserve quality, convert layers into a Smart Object first, which merges them as a single editable unit without destroying the originals.
Does PhotoQuill support merging layers?
Yes. PhotoQuill is free photo editing software with full layer support. Select multiple layers in the Layers panel and press Ctrl+E to merge them, exactly as in Photoshop.
