Hi, can someone explain to me why crop tool is grayed out. Its a multi layered file that've been creating by following a tutorial. One thing I noticed if I convert this photoshop file to jpg then crop tool works fine.
That is because the JPEG format doesn’t support layers or artboards, so the layers and artboards are converted to a single image of pixels as a side effect of converting to JPEG. With the artboards converted, the Crop tool works again. But the Ungroup Artboards command accomplishes the same thing more directly, without losing layers and reducing image quality through a JPEG conversion, so Ungroup Artboards is a less destructive and higher quality solution.
