PDF Studio can create PDF documents in a few different ways:
- Scan paper document into PDF

- Convert Images (gif, png, jpeg, tiff format) to PDF
- Convert Word documents to PDF (.doc format supported in PDF Studio 6, .doc and .docx formats supported in PDF Studio 7)

- Convert Text documents (.txt) to PDF

PDF Studio is also integrated with Google Docs and it is possible to convert Microsoft Office documents to PDF using Google Docs conversion services. All this can be done without leaving PDF Studio. Users can simply upload documents to their Google Docs account and then open the documents as PDF in PDF Studio. Choose "Open As PDF" in the righ-click menu (CTRL + click in Mac) after selecting a file in the Google Docs File Manager.

PDF Studio does not provide a PDF printer driver like Adobe does. In general, we found that this is not really needed as most applications these days include a Save As PDF function.

Under Mac, you can simply save a document as PDF from the Print dialog:

Under Windows, Office 2010 come with a "Save As PDF" function in each application (Word, Excel, PowerPoint). For Office 2007, Microsoft distributes a free add-in to Save As PDF:

To print any documents to PDF, there a number of free PDF printer drivers available for download on the internet for instance "CutePDF Writer". Once installed these printer drivers will show under the list of printers in your print dialog allowing you to save any file to PDF (including when you print HTML pages from the web).

It is also possible to convert Microsoft Office document to PDF by uploading documents to your Google Docs account and then opening the documents as PDF in PDF Studio. All this can be done without leaving PDF Studio.
