TC has qpdf, submitted by some good looking aussie guy which states amongst other things
An application that does structual, content preserving transformations on PDF files. It could be called pdf2pdf
It does not create from raw state a pdf, but once you have a pdf you can edit it with qpdf

if you have decent internet why not try cloud editor?
the site is free to use but asks to upgrade for extra features so I guess that makes it commercial so I shall be obtuse
the site begins with pdf and ends in escape and is a commercial site
and makes the following claims
Free PDF Editor & Form Filler
