PDF converter software works by converting the file extension of a document into something that is both readable and editable in other programs. PDF converter software is often used to convert compressed PDF files into Microsoft Word files.
Methods for converting PDF files to other document types online include Nitro, a company that converts an uploaded file using its own software and then emails it back in the chosen format. Free trials of the software are available to convert files both to and from the PDF format. An added bonus of PDF converter software is the ability to merge documents to create a compressed set of documents that can be emailed without restrictions. This is achieved by converting a document type back to PDF using the same software after making any editorial changes.
