A basic reader is mainly for opening, viewing, searching, and printing PDF files. A full editor adds tools for changing content, reorganizing pages, converting files, combining documents, compressing PDFs, adding annotations, and other document workflows. SoftwareCW’s PDF Technologies collection highlights PDF Reader Pro as more than a viewer, with editing, conversion, extraction, markup, compression, and merging features. Choose based on whether you only consume PDFs or regularly need to change and manage them.
