Converting .wps files directly to .pdf format.
Converting Microsoft Works Word Processor Documents directly to Adobe Portable Document Format (.wps to .pdf conversion) is quite straightforward, and can be accomplished by pretty much any currently available word processors or online document conversion tools.
The original software, Microsoft Works, was discontinued in 2009.
One option is to use Microsoft Word (2010 version and newer), as it allows users to import their old .wps documents and re-save them to numerous different formats.
Alternatively, you could try third-party software, such as LibreOffice Writer or Apache OpenOffice Writer, which are capable of converting .wps to .pdf.
