Advanced PDF Concatenator - Version 1.11 Advanced PDF Concatenator is an affordable utility that simplifies the task of merging multiple PDF files into one PDF document. By default the application combines all pages from the selected input PDF documents, however users are provided with an interface to define specific page numbers or page number ranges that should only be merged together. In addition to this, the application provides an interface to separate merged PDF files with optional blank pages. Advanced PDF Concatenator automatically persists most recently used output directory path, detects password-protected input PDF files, allows users to sort input PDF files by path, size and creation date and permits assignment of custom names to output PDF documents.
