Merging and flattening
Merging layers combines multiple layers together. Pixel, vector, mask, adjustment or image layers can be merged into a new merged layer or into the first available pixel layer beneath it in the layer stack.
The entire document can also be flattened to produce a single-layer document.
Once layers have been merged, they become a single layer and their previous contents are no longer separately editable. There are several ways of merging layers.
To merge all visible layers:
In the Layers panel:
- Click Show/Hide Layer to set the visibility of layers in the project.
- -click a layer and select Merge Visible.
A new layer is added one step above the selected layer. This layer is a merged copy of all visible layers.
To merge selected layers:
- On the Layers panel, select multiple layers using -click or -click.
- From the Layer menu, select Merge Selected.
The selected layers merge down into the lowest layer in the selection.
To merge a layer with a pixel layer below:
- On the Layers panel, -click a layer and select Merge Down.
The selected layer merges with the first available pixel layer beneath it.
To create a copy of all visible layers merged:
- On the Layers panel, click Show/Hide Layer to set the visibility of layers in the project.
- From the Edit menu, select Copy Merged.
A flattened version of the visible layers is added to the Clipboard.
To flatten all layers:
- From the Document menu, select Flatten.
The document will then contain a single flattened layer.
