Using LibreOffice as a PDF Editor - gHacks Tech News
Feb 13, 2018·PDF X-Change Editor, free. A bit old-fashioned as far as looks are concerned, but quite powerful even in the free version. Opens blazingly fast (in marked contrast to Libre Office, which takes ages). I also use PDF X-Change Lite (also free), from the same publisher, to convert to pdf any printable file created by a Windows program.
