Here’s a slightly polished version of your feature list in the same style:
Features
Edit existing text (including paragraphs, columns, and whole pages), change fonts, and adjust the basic layout directly in the PDF instead of only adding notes on top.
Insert, replace, and resize images; rearrange, add, delete, and rotate pages; and perform basic page operations such as cropping or merging multiple files into a single PDF.
Add comments, annotations, and simple signatures, and apply password protection and permissions for basic document security and access control.
If you tell me what kind of tool this is (editor, viewer, suite, etc.), I can tune the wording further to match its target audience (home users, business, IT admins, etc.).
