Free PDF editor for all platforms
It's quite rare for me to recommend software but this free PDF editor is so good it's the exception.
I get asked about PDF editors on a regular basis but till now all the free ones came with same sort of penalty, restrictions, advertising, in app purchases, but this one seems to be truly free.
It runs on Windows, MAC and iOS, and it's called PDFGear. You can see more and download your copy here https://www.pdfgear.com/
Read, edit, convert, annotate, compress, merge, OCR, organise, print, and sign PDF files across devices, AND you don't need to sign up for an account.
I've not tried this but it also includes ChatGPT3.5 at no extra charge which I will have a play with later.
