What is the WPD file format?
.wpd is a text document file associated with WordPerfect. Most word processors support this format. .wpd files store formatted text along with optional table data or images. Older releases used the proprietary WordPerfect Character Set; newer versions added Unicode support.
History of WordPerfect
WordPerfect was originally released in 1982 and quickly became one of the most popular word processor applications. It offered a wide variety of plugins and extensions that further expanded its capabilities. The introduction of GUI word processors made WordPerfect less relevant, only to later become displaced by more modern tools. WordPerfect is still actively developed by Corel, and .wpd is still used - particularly in US legal and government offices. Files carry the four-byte signature FF 57 50 43 and embed formatting codes among the text, enabling WordPerfect's distinctive Reveal Codes feature. LibreOffice Writer and Microsoft Word both open .wpd files; on Linux, wpd2odt converts them from the command line.
Security & safety
RISK: LOWA .wpd is a document, not an executable, so it is low-risk. Old WordPerfect documents could contain macros, but these only run inside WordPerfect and are rarely a modern threat. The main caution is privacy: .wpd files are often legal or government documents containing sensitive personal information, so do NOT upload confidential .wpd files to online converters - use offline LibreOffice or WordPerfect Office instead. Also avoid sketchy "free WPD viewer" download sites; LibreOffice is the safe, free tool.

Files begin with the signature FF 57 50 43 ("<0xFF>WPC"). The next bytes give the document area pointer and a product/file-type byte (0x01 = WordPerfect document) plus major/minor format version, so a tool can tell WP5 from WP6 from the header.

Frequently asked questions
How do I open a WPD file without WordPerfect?
Use LibreOffice (free, open-source) - File > Open reads WordPerfect documents on Windows, macOS and Linux. You can then save the file as DOCX or PDF. Microsoft Word can also import .wpd in many builds.
Can Microsoft Word open a WPD file?
Often yes - Word historically included a WordPerfect import filter. Microsoft has removed it from some recent versions, so if Word won't open the .wpd, use LibreOffice and re-save as DOCX.
How do I convert a WPD file to Word (DOCX)?
Open the .wpd in LibreOffice Writer (or WordPerfect Office) and choose Save As > Word 2007-365 (.docx). Check complex elements like footnotes and columns after converting.
What program created WPD files?
Corel WordPerfect (originally WordPerfect Corporation, then Novell, then Corel). It dominated the DOS era and remains common in US legal and government offices; Corel still sells WordPerfect Office.
Is WordPerfect still around?
Yes - Corel still sells and updates WordPerfect Office, and it still uses the .wpd format. But most people open old .wpd files in LibreOffice or Word rather than buying it.
Why is the WPD format common in legal documents?
Law firms, courts and government agencies adopted WordPerfect early (5.1 era) and kept it for features like 'reveal codes' and strong document automation, so .wpd persists in legal archives and case files.
