PDFCreator


PDFCreator is an application for converting documents into Portable Document Format 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.
Since 2009, PDFCreator has included closed source adware, toolbars and other controversial software that is installed by default.

Implementation

The application is written in Microsoft C# and released to the public at no charge. It works with 64-bit and 32-bit Windows versions including Windows 10. The actual PDF generation is handled by Ghostscript, which is included in the setup packages.
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 and PDF/X ), PNG, JPEG, TIFF, TXT. It also allows to digitally sign PDF documents.
Between 2009 and 2013 the installation package included a closed-source browser toolbar that was considered by many users to be malicious software. Although technically an optional component, the opt-out procedure used to be a two-step process, which was considered by many to be intentionally confusing. In addition to the spyware activity described below, the toolbar allowed one-click creation of PDFs from the current webpage and included a search tool. As of version 1.2.3, the opt-out procedure only required unchecking one checkbox during the installation process.
Since version 0.8.1 RC9 PDFCreator supports access to its functionality via an ActiveX interface, allowing any COM enabled application to make use of its functionality.
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-bit, 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.
Starting with version 3.0.0, PDFCreator ended support for Windows XP.

Adware toolbar controversy

Starting with version 0.9.7, PDFCreator included an adware toolbar. The end-user-license agreement for PDFForge Toolbar by Spigot, Inc., states that the software will:
Pdfforge, which created PDFCreator, wrote an FAQ entry regarding the toolbar that stated:
Since that time various versions of PDFCreator have included adware toolbars and other software with the installer, which many virus scanners identify as problematic or undesired software.
In March 2012 the company announced that the toolbar had been discontinued with version 1.3.0. The company stated:
As of 23 March 2012, PDFCreator included the MyStart toolbar by Incredibar. On 13 June 2012, PDFCreator once again included another controversial bundled software package, which tests as spyware, called SweetIM. In July 2012 the project disabled reviews and ratings on its sourceforge repository.
On 30 August 2012, PDFCreator version 1.5.0 was released which included an installer for the "AVG Security Toolbar." There was an option to disable installation of the "AVG Security Toolbar, but it was not clearly identified. Furthermore, installation of PDFCreator required acceptance of the AVG EULA even when installation of the "AVG Security Toolbar" was disabled.
On 23 October 2012, PDFCreator version 1.5.1 was released which includes an installer for iClaro Search. Compared to previous adware choices, once installed, iClaro cannot be removed using the "Add/Remove Programs" option.
On 14 January 2013, PDFCreator version 1.6.2 was released which includes an installer for Install Entrusted Toolbar. The setup screen for Install Entrusted Toolbar has a single option in black font. The description for Express reads:
In October 2013, PDFCreator was stealthily installing more software, including Amazon's Internet Explorer toolbar, without notifying the user.

Awards

The now defunct OpenCD project chose PDFCreator as the best free software package for creating PDF files in Windows.
In August 2008, InfoWorld magazine recognized PDFCreator with an Open Source Software Award from the field of more than 50 available open source or free PDF creation applications.
Both of these awards predate the inclusion of the contested spyware.
