I have several pdf’s in which I like to change text and or pages/pictures/headings etc.
How can I do this with your product
While there are ways to modify pdfs using Libre Office, LO does not have a pdf editor per se. If you find Adobe Acrobat Pro or DC too expensive for the features you use, try products such as Foxit, Master PDF Editor, Nitro PDF Pro, Nuance Power PDF, etc.
There are disk-based and online options, there are OS-specific and cross-platform options, and there are fee-based and free versions. Do a search on the web and look at each product to determine the best fit for your needs.
