Typical uses

Letterhead – type a letter in any program, save it as PDF, then lay your company letterhead behind it.
Stamps and seals – put a “PAID”, “COPY” or approval stamp on every page.
Pre-printed forms – combine typed answers with the blank form so both show on one page.
Backgrounds and frames – add a coloured border or certificate frame.

On top or behind?

On top always works and is best for stamps and logos – lower the opacity if it covers text. Behind the page puts the overlay underneath your content, which is what you want for letterheads. It needs pages with a see-through background: most PDFs made from Word, Google Docs or this site are see-through, while scanned pages and some designs are not – in that case use On top with a lower opacity.

Sizes

Fit to page scales the overlay to fit without stretching. Stretch to fill makes it cover the whole page. Keep original size centres it at its real size.

Frequently asked questions

What is a PDF overlay?

Laying the pages of one PDF over (or under) the pages of another, like printing on pre-printed paper. It is the quickest way to add a letterhead, stamp or background design to a document.

Is it free?

Yes, free with no watermark.

Should I choose “On top” or “Behind the page”?

On top always works and suits stamps and logos – lower the opacity if it covers text. Behind the page suits letterheads and backgrounds, but only shows if your document has a see-through background, which is true for most PDFs made from Word or Google Docs.

Can the overlay have several pages?

Yes. Choose “Page by page” to put overlay page 1 on page 1, page 2 on page 2 and so on, or “start again” to repeat a set of pages.

Is the text still selectable?

Yes. Both PDFs keep their text and vector graphics – nothing is turned into an image.

Are my files uploaded?
