PDFCreator is an application for converting documents into Portable Document Format (PDF) format on Microsoft Windows operating systems. It works by creating a virtual printer that prints to PDF files, and thereby allows practically any application to create PDF files by choosing to print from within the application and then printing to the PDFCreator printer. It contains optional closed sourceadware that is installed by default.
The application is written in Microsoft Visual Basic and released to the public at no charge. It works with 64-bit and 32-bit Windows versions including Windows 7, internally using mostly 32-bit code. The actual PDF generation is handled by Ghostscript.
Besides being installed as a virtual printer, PDFCreator can be associated with .ps files to manually convert PostScript to PDF format. PDFCreator can convert to the following file formats: PDF (including PDF/A (1b) and PDF/X (X-3:2002, X-3:2003 and X-4), PNG, JPEG, BMP, PCX, TIFF, PS, EPS, TXT, PSD, PCL,RAW. It also allows to digitally sign PDF documents.
Since version 0.8.1 RC9 (2005) PDFCreator supports access to its functionality via an ActiveX/COM interface; this allows programs written in other languages, like C#, Delphi, Visual Basic, .NET, VBA, Perl, Python, Ruby, WinBatch, Windows Scripting Host (JScript, VBScript), to utilise and control PDFCreator programatically.
The installation package includes a closed-source browser toolbar that is considered by many users to be malicious software (see below). Although technically an optional component, the opt-out procedure is a multi-step process which is considered by many to be intentionally confusing. In addition to the spyware activity described below, the toolbar allows one-click creation PDFs from the current webpage and includes a search tool.
PDFCreator allows the user to disable printing, copying of text or images and modifying the original document. The user can also choose between two types of passwords, user and owner, to restrict PDF files in several ways. The former is required to open the PDF file, while the latter is necessary in order to change permissions and password. Encryption can be either 40 bits, compatible with Adobe Acrobat 3.0 or 4.0, or 128 bits for Acrobat 5.0 or higher.
Starting with version 0.9.6, there is full support for Windows Vista and version 0.9.7 provides support for Windows 7.
