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.
The application is GPL-licensed free software, written in Microsoft Visual Basic.
The actual PDF generation is handled by Ghostscript. Besides being installed as a printer driver, PDFCreator can be associated with .ps files to manually convert PostScript to PDF format. It merge multiple files into one PDF.
[advt]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.
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.
