Extract text from WD3 files
To convert your WD3 file to another format, you need Web Dumper or other Web software.
To convert other file formats to the "Offline Project Index" file type, you need software like Web Dumper or a similar tool.
A .WD3 file is primarily a project index created by Web Dumper (version 3) or Offline Explorer. These files act as a map for websites downloaded to your local drive, storing the directory structure, link relationships, and metadata required to browse the site offline. A common difficulty is that users mistake the .WD3 file for the website itself; however, it is often just a small index file (under 100KB) that references a separate folder containing the actual HTML and image assets. Without the original software and the accompanying data folder, the file is useless.
A secondary but significant use case is as a data log from Spectrum Technologies WatchDog 3000 series weather stations. In this context, the file contains binary environmental data (rainfall, wind speed, leaf wetness) that is unreadable by standard text editors. Users typically need to convert these logs to CSV or XLSX for analysis in Microsoft Excel. For web projects, the best conversion target is PDF (for archiving) or standard HTML5 (for universal access).
Convert.Guru analyzes your WD3 file, detects the exact format, and lets you read the text inside.
Users also converted CW, TDK, ML20 and WD2 files.
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 WD3 converter.
