Frequently Asked Questions
Can I use this for digital letterheads?
Yes! Select your stationery/letterhead PDF as the overlay file and configure it as background or foreground.
How do page sizes behave?
The overlay scales automatically to fit the target page dimensions of the base document.
Is client-side processing lossless?
Yes. Vector paths and text fonts are preserved as native PDF objects without rasterization degradation.
Combine two PDF documents by overlaying page graphics, letterheads, and stamps. Set custom opacity, foreground/background ordering, and target page scopes.
How it works
- Choose the base PDF and the overlay file, such as a letterhead or watermark.
- Set it as a background or foreground layer, along with opacity and the target pages.
- Download the combined PDF.
Use this tool to add a watermark to a PDF or overlay a PDF, such as a letterhead or background template, onto the pages of another document. The overlay is scaled to fit each page, and vector paths and text stay as native PDF objects. Processing happens in your browser.
