PDF-Analyzer

PDF-Analyzer is a program with a pretty self-explanatory name - it lets you find out various details on PDF files, such as security information, as well as to make some modifications.
The interface of the application is outdated but easy to figure out, thanks to the intuitive layout. You can use the tree view to locate PDFs on your hard drive. Alternatively, you can drag and drop the selected file onto the main window of the application.
So, you can edit document fields concerning the title, subject, author, keywords, PDF version, encryption type and level, date of creation and modification, among others.
In addition, you can change file permissions in regard to printing, copying, editing, form fields, comments, content access, document assembling, JavaScript and RDF content. PDF-Analyzer allows you to reset the PDF password, view the changes in the default PDF viewer, as well as to print the file, just to name a few.
The application runs on a very low quantity of CPU and system memory, so it doesn't interfere with the runtime of active processes.
It has a good response time and worked smoothly during our tests, without hanging, crashing or popping up error dialogs. First-time and experienced users alike can tinker with the tool's options.
