powerful pdf editor
 

I'm looking for a pdf editor that permit me to resize the content of all pages, and add footer with page number and image.
I tried InkScape (but I can modify only one page) and Libreoffice Draw (but I don't found the features I'm looking for).
Something like Adobe Acrobat or Pdf Architect.

Do you absolutely want it to be a GUI? If not, there're many great command line tools, e.g. mutool (part of mupdf), cpdf, sejda-console (the last free release is 3.2.85), qpdf, on some distros the good old pdftk or its newer port to Java pdftk-java may be available.

A good GUI tool is Master PDF Editor, but the free (as in beer) version has limited functionality, albeit older free versions (3.x) were not so limited in scope and still can be downloaded.

Free version of Sejda PDF Desktop imposes some daily and size limits.

The venerable PDFedit still may be available on older distros. It requires Qt3 and is rather basic than powerful. Probably won't cope with newer and complex PDF files.

If you're ready to pay, there's also PDF Studio. Cannot really comment on this as I never used it.

Another option is to install Wine and run a Windows PDF editor.

Or you may use some online PDF edit service if you're OK with uploading your files to them.

Sorry, the link ist wrong. See this post.

I've been using PDF Studio Pro for a few years now, both on Win 7 and, now, on Linux Mint. The pro version falls between Adobe Acrobat Standard and Acrobat Pro in features. Unlike Acrobat, PDF Studio in not cloud or subscription based and never expires; you can continue to safely use a version even after a new version comes out. It's also much less expensive to buy once upfront than to essentially rent Acrobat from Adobe.

While there was a learning curve I had to overcome, once that was out of the way, I like it a lot better than I did Acrobat, especially when using multiple monitors. I have PDF Studio set as my default PDF viewer as well as using it for PDF creation and editing.

Oopsie!
