LibreOffice Draw

LibreOffice Draw, part of the free and open-source LibreOffice productivity suite, is a versatile vector graphics editor that doubles as a capable, if unconventional, PDF editor. Its strength lies in treating a PDF page as a collection of objects (text boxes, images, shapes) that can be moved, deleted, or modified. This allows for surprising flexibility in editing existing PDF layouts, adding new elements, or creating PDFs from scratch. It can also export directly to PDF.

However, it is not a dedicated PDF editor; its workflow is different, it lacks native OCR, and editing flowing text within paragraphs can be cumbersome. It is a powerful tool for users who already use LibreOffice, need a free and open-source solution for manipulating PDF page elements, and are willing to learn its unique approach. For basic edits and PDF creation within a full office suite, it's an invaluable hidden gem.
