I assume the "pdftk-all" port you are referring is pdftk-java by Marc Vinyals (https://gitlab.com/pdftk-java/pdftk). You mention file pdftk-all.exe. Do you have a copy of this wrapper .exe for Windows? If so, have you tried renaming it to pdftk.exe and substituting it for the original pdftk.exe in your PDFTK Builder program folder to see if PDFTK Builder produces the desired output when calling it? See last paragraph below for results of my test. I downloaded the pdftk-all.jar (v3.3.3) from the pdftk-java...

Your guess at how PDFTK Builder was performing 'Stamp first page only' is correct and was implemented in v3.0 (Apr 2007). I added support for multibackground/multistamp in v4.0 (Nov 2017) which fortuitously allowed the workaround you found of adding a second blank page. PDFtk does not have a function to generate a blank page which made having to add a blank page to single-page stamps a problem. Instead, I used 'dump_data' to save the bookmarks and metadata from the original file and reapplied them...

Version 4.1.9 (15 Nov 2025) is a minor update of PdftkBuilder to fix a problem reported in user chrisemb's topic below regarding bookmarks (outlines) being deleted when a PDF was stamped with the 'Stamp first page only' option selected. This problem which affected the 'Stamp' and "Background' functions on the 'Mark Pages' tab had apparently managed to escape notice since those functions were implemented back in 2007 (v3.0). The problem did not appear if all pages of PDF were stamped - the default....

Version 4.1.8 (6 May 2025) is a minor update that (1) fixes a recently reported problem with the 'Advanced' tool (on Tools tab, Set 4) and (2) deletes the empty temp working folder that was being left when the program was exited. FYI: PDFtk Builder is also available on PortableApps.com . That site accounts for 10X the number of downloads of PDFtk Builder than this project site. While PortableApps.com maintains their own website, their .paf.exe files are actually downloaded from a PortableApps project...

You discovered a long-standing latent problem with the error-checking of the user-edited command template string in the 'Advanced' tool which caused valid 'multibackground' and 'multistamp' operations to be rejected (Error A04: No PDFtk operation found in template). The fix is simple and will be corrected in the next release. It is not necessary to resort to using the 'Advanced' tool to perform multibackground or multistamp operations. The Stamp and Background options on the 'Mark Pages' tab automatically...

I am releasing Version 4.1.7 today, 2 Dec 2024, on an expedited basis to fix a serious bug which I noticed just last week while giving a demo to a friend. The error occurs in prior releases of PDFTK Builder Enhanced when merging or interleaving the pages of two or more PDF documents and any file below the top file in the ‘Join Files” list has more than one page range entered in its Pages box. For those files, the first page range would be taken from the correct file, but additional page ranges would...
