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.
I love PDFArranger. It has basic functions such as rotate, add or delete pages and it comes very handy for large documents. Also It is available on Linux, Mac and Windows: https://github.com/pdfarranger/pdfarranger
