Filevolcano.com provides a set of very useful tool for manipulation of PDF documents:
Described tools are very useful e.g. when there is a need to create single PDF document from multiple independent photos/images or documents. As an example it might be a letter to an Office/Court with multiple attachments. Having a letter to an Office/Court in a form of single PDF is very comfortable.
Most often the parts of other documents or photos/images are used as attachments of the final document/letter. Using Selected pages extractor its possible to change attachments to contain only needed pages. Using Photo to PDF converter we receive photos/images in pdf format, which makes it possible to attach these to the final document/letter.
PDFs merger is for joining main document with the attachments into the final document/letter. Sometimes it is necessary to separate the attachments. Great solution for this is to insert single page with attachment title before each attachment. For whole page texts/titles generation there is Whole page text generator.
The described tools make it easy to prepare a letter to an Office/Court.
