Вроде pdftk такое умеет: background <background PDF filename | - | PROMPT> Applies a PDF watermark to the background of a single input PDF. Pass the background PDF's filename after background like so: pdftk in.pdf background back.pdf output out.pdf Pdftk uses only the first page from the background PDF and applies it to every page of the input PDF. This page is scaled and rotated as needed to fit the input page. You can use - to pass a background PDF into pdftk via stdin. If the input PDF does not have a transparent background (such as a PDF created from page scans) then the resulting background won't be visible - use the stamp operation instead. multibackground <background PDF filename | - | PROMPT> Same as the background operation, but applies each page of the background PDF to the corresponding page of the input PDF. If the input PDF has more pages than the stamp PDF, then the final stamp page is repeated across these remaining pages in the input PDF. stamp <stamp PDF filename | - | PROMPT> This behaves just like the background operation except it overlays the stamp PDF page on top of the input PDF document's pages. This works best if the stamp PDF page has a transparent background. multistamp <stamp PDF filename | - | PROMPT> Same as the stamp operation, but applies each page of the background PDF to the corresponding page of the input PDF. If the input PDF has more pages than the stamp PDF, then the final stamp page is repeated across these remaining pages in the input PDF.
