What is difference between PDF and Word document?
PDF stands for Portable Document Format, created by Adobe. This allows for distribution of such documents with the possibility to restrict edits or changes. Best use is for original documents that bear signatures and the like, where you would not like someone to be able to “lift” the signature or the stamps. PDF documents can be edited if you have the full version of Adobe, but you have the possibility to lock the document so even the full version cannot be messed with. Word documents are editable. Good for drafts, sharing with collegues, fine for unsigned documents, or for printing out to be signed.
