When to Use a Letterhead Overlay
A letterhead overlay is perfect for branding invoices, proposals, contracts, and internal reports with your company's header, footer, or border design. Instead of editing the original document, you simply upload it alongside a 1-page template — your logo, address, and styling are applied to every page in seconds.
How It Works
Upload your multi-page PDF and a template file (either a 1-page PDF or a JPG/PNG image). Choose whether the template goes on top of or behind your content. The tool then draws the template onto every page using pdf-lib and saves a new file. Everything happens locally — your documents are never uploaded to any server.
