About This Tool

PDF Layer Manager allows you to view and manage Optional Content Groups (OCG) in your PDF documents. OCG layers are used in technical drawings, maps, and complex documents to organize content into toggleable layers.

View all layers in your PDF, toggle their visibility, add new layers, delete unwanted ones, or rename existing layers. This tool is essential for working with layered PDFs like architectural plans, CAD exports, and print-ready documents.

All processing happens locally in your browser, ensuring your documents remain private and secure.

Frequently Asked Questions

What are PDF layers (OCG)?

Optional Content Groups (OCG) are layers in a PDF that can be shown or hidden. They are commonly used in CAD drawings, maps, and complex documents.

Why does my PDF show no layers?

Not all PDFs contain layers. Layers are typically added during PDF creation from design software or CAD applications.

Will layer changes affect the original content?

Layer visibility changes only affect what is displayed or printed. The actual content remains in the document.
