The file extension WPS indicates a document file created by Microsoft Works prior to 2006. Today's equivalent of the WPS is the DOC file. If you have a WPS document and want to convert it into a format readable by more computers, convert it to a PDF file. The simplest way to convert a WPS file to a PDF is to download free software that will perform the conversion for you.
Launch Microsoft Works. Click "File," then "Open" and locate the name of the WPS file and click it to open.
Save the file with a DOC exension by clicking "File" and then "Save As." In the drop-down "Save as Type" box, select "Word 97-2000 & 6.0/95 - RTF (*.doc)" and then click "Save."
Navigate to the Open Office website.
Click "I want to download OpenOffice.org" to start the free download. Double-click the icon on your desktop and follow the directions to install OpenOffice.
Click on the OpenOffice Writer icon on your desktop. Click "File," then "Open" and locate the name of the DOC file and click it to open.
Click "File" and then "Export as PDF."
After your file is saved as a PDF, you will be unable to edit it using OpenOffice software. Keep a copy of the file in DOC format in case you need to edit it later.
