Extract text from Glulx Blorb game archives (GBLORB)
To convert GBLORB game archives to another format, you need Gargoyle or other Game software.
To convert other file formats to the "Glulx Blorb Game File" file type, you need software like Gargoyle or a similar tool.
The .gblorb file is an interactive fiction game package designed for the Glulx virtual machine. It functions as a specialized archive (wrapper) that bundles the compiled game code (typically a ulx file) together with multimedia resources like jpg images and ogg audio into a single, distributable file. Players load this file into interpreter software like Gargoyle to play the text adventure game.
While highly efficient for game distribution, the .gblorb format creates significant access barriers. It is a proprietary community format. Standard archive managers like WinRAR or 7-Zip cannot open it. Media players cannot read the audio or images trapped inside. This causes frustration when users simply want to extract the game's soundtrack, view the cover art, or retrieve the base ulx file for debugging.
The best targets for converting or extracting data from a .gblorb file are standard media formats like jpg, png, and ogg, or the raw ulx code format. Extracting these files strips away the playable game structure but recovers the underlying assets.
Because this file uses a niche chunk-based structure, it is difficult to open or convert with standard online tools. Often, only dedicated interactive fiction tools can properly read or export the data. However, just drag and drop your file onto convert.guru to identify the format, inspect the file, and show text or internal content. If our analysis detects supported underlying or embedded formats, viewing or asset extraction may still be possible.
Convert.Guru analyzes your GBLORB file, detects the exact format, and lets you read the text inside.
Users also converted BLORB, GLKDATA, ZIP, TZST, 1-STEP and ZC files.
If you want to convert GBLORB file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use Gargoyle or similar software from the "Interactive Fiction Game Package" category. In the File menu, look for Save As… or Export….

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 GBLORB converter.
