Open source reading and editing tools for PDFs are often more secure and reliable alternatives to the applications residing in the first pages of "PDF editor" search results. There, you're likely to see proprietary applications with hidden limitations and tariffs, lacking sufficient information about data protection policies and hosting. You can have better.
Here are five applications that can be installed on your Linux system (and others) or hosted on a server. Each is free and open source, with all the necessary features for creating, editing, and annotating PDF files. Being covered are LibreOffice, ONLYOFFICEdocs, PDF Arranger, Okular, and Xournal++.
