By modifying the source file, for which word processor or other computer application may have been used, you can easily write in a portable document file.

1. How Can You Edit a PDF File and Make it More Readable?
This is a real popular format used for the sharing and creating digital documents. Since
files created in this format can be viewed across any platform or operating system, it is
extensively utilized. At the initial stages, only Adobe Acrobat was meant to be used to
read a file in pdf. However, with changing time, there have been many utilities developed
that can be used to read files created in portable document format. In order to have an
accurate output when editing an existing file, there is generally a need of the original
document that was used for its creation. This is more of an open-standard format that
permits activation of digital signing and password protection mode for the documents
that need to be shared with others over the Net. At times, to edit content, people convert
documents from pdf to word using pdf file converter as well. So the basic three things
that you would need for being able to write in a file in this format are:
•Source file
•Editor and viewer program
•Word processor or image editing program
By modifying the source file, for which word processor or other computer application may
have been used, you can easily write in a portable document file. Once after having done
modifications in the source file, you can save it in this format. So all the edited content
would be saved in the converted files like it is in the original file. Given that this option
does not work for you, which means, if you have no original source file available then
another method needs to be used. If only the main file in this format is available, then you
would have to use an editing program. The program would allow you to write, edit and
upgrade the content in your file. You would have to search over the Net to find a capable
tool. All you need to do after finding an application is to run it. So, it is after launching the
application that you can open a file, in which you need to edit the matter. This will then
show you the main interface and then you can proceed with writing and editing process in
your portable document file. You can insert objects, columns, re-position images, correct
typed letters or reveal some additional content. It would be better if you do not attempt
editing multiple pages as a single document but only by taking one page at a time. For
easier editing, individual window is opened for every pdf page.
