Manage a PDF's Optional Content Groups | the hidden layer system used in CAD exports, maps, and annotated documents | to show or hide specific content.
Upload a PDF that contains optional content layers.
Review the detected layers and toggle their visibility.
Export a PDF with your chosen layer visibility settings applied.
OCGs, often called "layers," let a single PDF contain content | like translations, annotations, or CAD details | that can be shown or hidden without altering the underlying document.
Not all PDFs use OCGs; this feature is mainly found in exports from CAD software, GIS/mapping tools, or PDFs authored with layer support in mind.
Yes, exporting with a layer set to hidden removes it from the visible output while keeping the file structurally valid.
