About This Tool
Flatten PDF layers into a single layer with our free online layer merger. Combine all layer content into one static layer, removing layer visibility controls for consistent document appearance across all PDF viewers.
Layered PDFs from Adobe Illustrator, CAD applications, and design software may display differently depending on viewer settings. Flattening merges all visible content into one layer, ensuring everyone sees the same output regardless of their PDF application.
All layer flattening happens locally in your web browser. Your documents never upload to external servers, ensuring privacy for architectural drawings, design files, and technical documents requiring layer consolidation.
Perfect for finalizing CAD exports, preparing layered designs for distribution, ensuring consistent appearance of technical drawings, or archiving layered documents in a static format. Works with layered PDFs from Adobe Acrobat Pro, AutoCAD, and design applications. Preserves all visible content while removing layer switching functionality.
