Flattening layers in image editing merges visible layers into the background, reducing file size and filling transparent areas with a color.
Flattening layers in image editing is a process where all visible layers are merged into the background layer, resulting in a single layer with all the information combined. This action reduces file size by eliminating the need to store information from multiple layers. Additionally, any transparency in the original layers is removed, and the areas that were transparent are usually filled with a chosen color, commonly white.
