Portable Document Format file! widely known as PDF file, is the most used format to share documents online. If you move back just a few years back, After the fist decade of 21st Century, the most common program to create documents online was MS Word. Though MS Word is still like a hot selling cake, but to send the files through mails or sharing through FTP, PDF has become a reliable option now. Sometimes due to corruption of PDF files it is not possible to open it. So before I tell you how to fix damaged PDF files you must know why it is preferred more than other formats.

Reasons for using PDF Format

One of the basic reasons behind this, is that PDF is not editable by a normal user. Which makes it secure. Since there are many paid tools available online that can edit a PDF file easily, but if you have implemented additional security to your PDF file, even a commercial tool cannot edit it until the security is removed. I too use Adobe Acrobat X, but If the file is secured, I fail editing it.

Disadvantages (Cons)

I mentioned above as well, that a PDF cannot be edited easily as compared to other formats like .doc or .docx. People find it difficult to edit these files.
If you want to edit a PDF file, you need to buy a commercial PDF editing tool, the better one is always expensive.
Other documents can easily be accessed or opened with the default programs in the OS package. Whereas to open a PDF document, you need Adobe Acrobat reader or Foxit reader.
