So get your arms around these free tools to conveniently modify and add effects to the PDF documents.
Adobe Reader XI
The first tool on my list is Adobe Reader XI. This free tool offers impressive range of annotation functions, allows commenting and digital signing. Moreover, the users can documents can also be saved as a text file. You will have to pay to unlock other features like converting documents into PDF format, exporting PDF files etc.jPDF Bookmarks
As its name suggests, this tool allows bookmark editing including deletion, modification and addition. Its GUI interface is very user friendly. Moreover, you can also create bookmarks that support wide range of media formats.
jPDF Tweak
This java-based application is more versatile than the previous jPDF Bookmarks. You can easily split/combine files, attached documents, add digital signature, give page numbers, water marks and much more. It is not as user-friendly as the above mentioned jPDF Bookmark.FreeOCR.net
This tool is quite handy in transforming the content of a PDF document into raw text. It is a reliable utility that can only handle text and leaves behind the images. For best performance, scan the pages individually. However, the entire PDF file can also be transcribed in one go. But the users would have to perform more post-scan editing. Overall it does the job reasonably well.PDF-XChange Viewer
This functionally rich tool is light-weight. The paid version provides the convenience of digital signature, addition/erasure of pages along with the flexibility to attach files. The free version also does many tasks like document searching, markup, annotation etc. In short, it handles the operations very efficiently.PDFTK Builder
New features have been added along with a GUI (graphical user interface) in the previous PDFTK command-line utility.
You can secure the document with password, include stamps, change background and also rotate the pages. Entire document as well sections can also be collated. The interface is quite comprehensive and incorporates fair amount of functionalities.
PDF Split and Merge
The name of this tool kit provides a clear picture of its functionality. Multiple PDF documents can be easily integrated, whereas you can split the file and extract single pages. It eases task with good amount of customization, but the interface is not that much attractive. But still it is reasonably well for document attachments, page rotation and splitting off components.SpeedPDF Stamp
Functionality of this utility is very limited, but still is quite handy. You can embed custom stamps, and seamlessly place it on the back/front of the pages. Sybrex Systems designed this tool kit.7-PDF Maker
This well designed and useful application can efficiently convert broad range of image and file formats. It supports more than 80 formats. This free PDF convertor quickly transforms almost any document into PDF format.
