I’m not looking for a full PDF editor. Only to do tasks like merging and splitting PDFs, removing pages, or creating a PDF from a bunch of images.
https://www.ilovepdf.com is very handy, but I don’t like the idea of uploading my documents to them, especially if they have sensitive data.
Master PDF Editor. The current version is paid, but version 4 is free. It’s a good swiss knife like PDF tool.
