About W51 files
The .w51 file extension is predominantly a legacy word processing document created by WordPerfect 5.1 for MS-DOS, a dominant text editor from 1989. In a minority of cases, it functions as a SEDAR compressed document archive used by the Canadian Securities Administrators for financial filings.
You can still open these text files using modern versions of Corel WordPerfect or the open-source LibreOffice suite, which includes robust legacy import filters.
Users encounter significant disadvantages with the .w51 format today. It is an obsolete, proprietary binary format that modern web browsers and mobile devices simply cannot read. Furthermore, modern tools like Microsoft Word often block these legacy files entirely due to modern security policies or lack the necessary rendering engines, forcing users to find immediate workarounds.
To make these files usable, you should convert them to DOCX, PDF, or RTF. Converting to PDF is ideal for preserving historical layouts, while DOCX is best for text editing. Note that complex legacy formatting, custom printer macros, or obscure fonts from the MS-DOS era will likely be substituted or lost during modern conversion.
Because this is a closed, proprietary 1980s format, standard online converters often fail to process it. Just drag and drop your file to identify the format, view it, and convert it when possible using convert.guru. Even if full layout conversion fails, our analysis can often inspect the file and extract the raw text from the vintage binary structure.
Convert.Guru analyzes your W51 file, detects the exact format, and lets you read the text inside.

The W51 Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our W51 converter.
