"I am looking for some tools on Linux I can use to edit PDF documents. Any recommendation much appreciated!"
Over the past few years, I've tried a variety of Linux PDF editing apps and I've had a very mixed experience depending on what I was trying to do. For example, simply filling out a PDF form was a nightmare. If that's what you want to do, I'd suggest using a web app like DocuHub or Adobe's fee web pdf editor, https://www.adobe.com/acrobat/online/pdf-editor.html I recently used pdfmod, to remove a page from a pdf and it worked great. Lightweight, simple tool. There's a PDF app that uses EMACS for editing, elpa-pdf-tools, if you're good & comfy with using EMACS. If you've a graphical package manager installed, it's easy to search on PDF and read the description of each pdf tool and should find one that's designed and good for the specific tasks you want to do.
