Stamping a #PDF file (e.g. add a signature) in 2026 on #Linux seems to still be an impossible task without some weird gimmicks. (I don't mean digital signing, BTW.)

LibreOffice Draw could work but messes up with the fonts.

pdftk can do it but it needs the “stamping” signature file to be correctly sized and positioned —good for batch processing, bad for single files.

Any ideas?
