      Flatten Layers in a PDF File

      Ensure all elements in a PDF display correctly by flattening layers.

      Some PDF files include multiple layers that can cause blank or missing pages when viewed in certain apps. Flattening the file merges all layers, ensuring all elements are visible and display as expected.
