Add color overlays to your PDF documents
Merge two PDFs visually by overlaying pages from one document onto another. Ideal for adding templates, watermarks, form backgrounds, letterheads, or branding elements—done entirely in your browser.
Select a base PDF and an overlay PDF to superimpose their contents page-by-page. Great for form overlays, design guides, invoice stamps, and more.
Control position, transparency, scale, and alignment of the overlay PDF. Perfect for semi-transparent stamps, letterheads, or forms without disrupting base content.
All processing is done locally in your browser. Your PDFs never leave your device, ensuring privacy and data security even for confidential files.
Overlay pages automatically aligned by index (page 1 on page 1, etc.). If overlay has fewer pages, choose to repeat or leave remaining base pages untouched.
Use it on desktop, tablet, or mobile. Our overlay tool is fully browser-based and works without needing to download or install anything.
Whether you’re a business adding branding, a teacher overlaying answers, or a designer adding templates — this tool makes it simple and powerful.
Overlaying lets you reuse a standard form, watermark, or design across multiple PDFs. It’s perfect for branding, approval stamps, report covers, and document templates.
Use transparent overlays (PDFs with no solid backgrounds) for watermark-like effects. Align carefully when overlaying form templates or scanned designs.
