DaVince Tools is a group of programs for converting JPEG, TIFF, and text files to Portable Document Format (PDF) files. These programs can be run from either a Windows application or in a DOS command-line environment. As a bonus, included with the product is a TIFF tag viewer and a PDF maze maker. These are standalone programs, which means they are not plug-ins for other applications nor do they require other software in order to run. There is a converter for each file type: tiff2pdf, jpeg2pdf and txt2pdf. The Windows application, wdavince.exe, provides a single GUI interface for accessing all the converters. A DOS command-line environment is also available, where program execution can be controlled by either the command line or a command file. All converters share these common features: create 1 PDF for each file, directory or all files; PDF compression support; GUI, command line and command file support; Bookmark support.
