Extract text from WORLD files
To convert your WORLD file to another format, you need Terraria or other Game software.
To convert other file formats to the "Map / Simulation File" file type, you need software like Terraria or a similar tool.
The .world extension is a generic container used by various software engines to define virtual environments, making it one of the most ambiguous file types you will encounter. It is most commonly associated with video games like Terraria (stores terrain, items, and structures in a GZIP-compressed binary format), The Sims 3 (packages town layouts), or robotics simulators like Gazebo (uses XML-based SDF to describe physics and lighting).
The primary issue with .world files is their proprietary nature; a file created in Terraria is completely unreadable by The Sims, and often even incompatible with different versions of the same game. Users frequently struggle with version mismatches, binary encoding that prevents text editing, and the inability to view the full map outside the game client. For Terraria players, the goal is often converting the binary map to a high-resolution PNG image to view the entire world layout or exporting data to JSON for editing in tools like TEdit. For Gazebo users, the workflow involves converting the SDF-based .world text files into standard 3D formats like DAE (Collada) or URDF for interoperability with other physics engines.
Convert.Guru analyzes your WORLD file, detects the exact format, and lets you read the text inside.
Users also converted 3DX, DOCX, DOC, PNG, SIM, SIMS3PACK and PACKAGE 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 WORLD converter.
