Frequently asked questions

Is overlaying PDFs free?

Yes. The overlay tool is free and unlimited, and it never uploads your files.

Do the base PDF and letterhead stay private?

Yes. Both documents are combined locally in your browser, so neither the content nor the template reaches any server.

Is there a file size limit?

No hard limit. Processing is local, so capacity depends on your device's memory rather than on any server quota.

Can I choose where the overlay goes?

You choose whether the overlay sits below the content, like a letterhead, or above it, and whether it applies to all pages or only the first.

Does the overlay stay sharp when printed?

Yes. The overlay is applied fully vector, so letterheads and templates keep their original crispness at any print size.
