How to export layers?

Hi! The quick way for individual layers is: in the Layers panel, select the layer you want, right-click it, and choose Export As — then choose PNG and export. Repeat for each layer you need as its own PNG file. For a faster export you can also use File > Export > Quick Export as. Adobe's guide is here: https://helpx.adobe.com/photoshop/desktop/save-and-export/save-files/save-in-png-and-gif-formats.html — it notes you can select layers in the Layers panel, right-click, and choose Quick Export or Export As. Hope that helps!
