iSkysoft PDF Editor Pro will not only let you merge different PDF files, it also lets you split files into different documents. If you have bits and pieces of PDF files you wish to turn into one big, organized file, this is just the program you need. Based on my interaction with this software, the optical character recognition can come in pretty handy. The character recognition is great and works well. This is exactly why iSkysoft PDF Editor Pro comes with an intelligent OCR feature.

When your PDF file is actually a converted scanned document, editing may be impossible. You can also choose to convert PDF to other file formats, create a new PDF file or combine PDF documents. In this mode, you can edit text, edit embedded images, completely remove pages, re-arrange pages, add watermark and much more. Pages that are out of proportion can be cropped, you can as well insert new blank pages. You can choose to edit your existing PDF files. At startup, you’re presented with four useful options. To get started, it’s as easy and dragging and dropping the file to be edited into the program UI.
