About PDF Layer Manager
Control the Layers Inside a PDF
Some PDFs are built like design files: annotations, translations, measurements, print marks or alternate versions can sit on separate Optional Content Groups — usually called layers. Viewers that support OCGs let you switch those layers on and off, but most PDF tools give you no way to change the defaults or clean up the list.
This tool reads the layer configuration from your PDF and lets you edit it directly. Flip a layer's default visibility, rename cryptic group names, add a new empty layer for later authoring, or remove entries you do not want to ship. The page content streams are not rewritten — the changes live in the document's /OCProperties configuration.
What You Can Do
Everything operates on the layer list, not on the page graphics themselves.
Toggle Visibility
Set which layers are shown by default when the PDF is opened in a viewer that supports Optional Content Groups.
Rename Layers
Turn internal names like 'OCG 14' into clear labels such as 'Measurements' or 'Spanish text'.
Add Layers
Create a new empty Optional Content Group that an editor can assign content to later.
Delete and Restore
Mark a layer for deletion, then undo it before applying — nothing is final until you download.
Page Preview
Check the document while you work with page navigation and zoom controls.
Encrypted File Handling
Encrypted PDFs can be inspected in view-only mode; unlock them first to edit their layers.
Visibility Is a Default, Not a Redaction
Hiding a layer only changes whether it is visible by default. The underlying content remains inside the file, and a reader can usually turn the layer back on. That makes this tool useful for presentation defaults — like shipping a drawing with measurements off — but not for removing sensitive information.
Deleting a layer removes the group from the layer configuration rather than erasing page graphics. If your goal is permanent removal of content, use a redaction or content-editing workflow instead of layer controls.
How It Compares
Layer editing is a metadata job. This tool keeps it that way.

Private by Default
Layered PDFs often come from CAD exports, prepress files, legal review sets or multilingual documents — exactly the kind of material you should not upload to a random converter. OxygenPDF parses the file and writes the updated configuration entirely in your browser.
Close the tab and the document is gone. There is no queue, no server-side processing and no copy retained after the download.
