PDF Protector Splitter and Merger Pro is an all-in-one utility that allows you to work with PDF documents in a number of ways. The program allows you to split a PDF document into multiple files, merge two or more documents into one, and protect the content of your files. With it, you can also extract images and text from your PDFs.
The application has a tabbed, easy-to-use interface that makes it easy to work with. Once you choose the task you want to perform, it is simple to load PDF files or folders into the conversion list. The different PDF functions are arranged by tabs, and the pop-up menu with options changes depending on the function you choose. If you decide to split a PDF, the menu will show you options to select the page range or determine the number of pages you want to extract. The image extractor, in turn, lets you obtain the images contained in PDF file in the format of your choice, which can be JPEG, PNG, TIFF, GIF, BMP, etc. Moreover, there are multiple PDF security options to protect the content of your documents from copying or printing and encrypt your files with a password. Additionally, this PDF app supports batch conversion, thus it is possible to work with more than one document at a time.
Overall, the application does a very good job splitting, merging, extracting text, and protecting PDFs, except for the image extraction feature, which gave me several error messages and output distorted photos, regardless of the image format chosen. Anyway, you can download the free trial version, which is fully functional, and decide for yourself if it is worth buying.
