Converting files from other format to PDF is a smart idea if you want to create E-books for selling or making contract or some government report. Adobe Acrobat is the king when creating PDF files but editing files with Adobe Acrobat is never as convenient as Microsoft Office. Actually, there are some tools that may alter Adobe Acrobat. Most importantly, most of these tools are FREE.

Then install the plug-in on your computer. When you create Office document, including Word, Excel, PowerPoint and other Office files, click Save As, then choose PDF to help you publish a copy of the document as a PDF file.
