I had Adobe Acrobat Pro which does that, but I uninstalled it since it was taking way too much space and I basically never used it.

Adobe reader. if you use anything else you will eventually have to install adobe at some point anyway, due to nothing else supporting pdf 100%. such as the secure pdfs that download the content when you open them

Libreoffice Draw can modify PDFs element-wise. You can pick text fields, pictures, etc. I wouldn't bother modifying PDFs myself but you can give it a try.

What I do is I convert it to SVG using Inkscape, edit the SVG code (I use Sublime Text for this), and then convert it back to PDF using Inkscape again.

SVGs and PDF have some incompatible elements though.
