To convert other file formats to the "Project File / Database" file type, you need software like CoffeeCup Web Form Builder or a similar tool.
About FB files
The .FB file extension primarily acts as a project file for CoffeeCup Web Form Builder, a tool for creating online web forms. It can also function as a database file for the open-source Firebird SQL relational database management system, or as a binary serialized data file for Google FlatBuffers. Other minor uses include game cache data for Cataclysm: Dark Days Ahead and legacy AOL Instant Messenger contact lists.
Because .FB is an overloaded extension, users face significant challenges when sharing or archiving these files. The CoffeeCup .FB format is a proprietary ZIP container. It holds XML data and web assets, but it requires a specific software installation to edit the form structure. The format is useless for users who just want to view the final web form. Similarly, Firebird .FB files are raw binary databases that cannot be queried without running a specialized SQL server environment.
To make the data accessible, conversion or extraction is strictly required. For CoffeeCup projects, the ideal target is exporting to HTML, CSS, and PHP using the original software. Alternatively, renaming the file to ZIP allows you to extract the raw XML and image assets, though the form's interactive logic will be lost. For Firebird files, you must dump the database into standard SQL or CSV formats for broader compatibility.
This file format is difficult to open or convert blindly because standard converters cannot guess which of the dozens of .FB variations you possess. Usually, only the original software can properly read or export the embedded data. We will inspect the file signature, show internal text content, and if our analysis detects a supported underlying format like a standard ZIP archive, extraction or conversion may still be possible.
Convert.Guru analyzes your FB file, detects the exact format, and lets you read the text inside.
If you want to convert FB file to MP4, VIDEO, VB or PDF, you can use CoffeeCup Web Form Builder or similar software from the "Web Form Project or Database" category. In the File menu, look for Save As… or Export….

The FB 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 FB converter.
