About HND files
The .HND file extension is primarily a HelpNDoc Project file developed by IBE Software. It serves as the master project container for authoring help manuals, documentation, and eBooks. Internally, a modern .HND file is structured as an SQLite database. This means it stores text, tables of contents, keywords, and internal relationships in an organized, but proprietary, relational structure. Other uses for .HND files include medical imaging data generated by Varian Medical Systems (specifically Varian Eclipse) and bridge deal records for Bridge Base Online.
Users often need to convert .HND files because they are completely useless without the original software. You cannot open a HelpNDoc project natively in a web browser, and sending an .HND file to a client means they must install a specific Windows program to read it. Furthermore, the medical and card-game variants are even more tightly locked to their respective niche software, making data sharing difficult.
The best solution is to export the .HND project to universally accessible formats like PDF, HTML, CHM, or EPUB. However, because the file is a complex database container (not a flat document), standard online file converters will fail to process it. They cannot render the internal proprietary layout or execute the built-in compiler. Often, only the original software can properly read or export the data. If our analysis detects the underlying SQLite structure, viewing or text extraction may still be possible.
Convert.Guru analyzes your HND file, detects the exact format, and lets you read the text inside.
Users also converted HNDGP, SAV, IBD, 3 and BSC files.

The HND 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 HND converter.
