Frequently Asked Questions
Got questions? We have got answers. Find out everything you need to know about our Terraria map viewer and editor.
General
Terraworld.dev is an advanced online viewer and editor for Terraria world files (.wld). It allows players to upload their save files directly in the browser to view the entire map, locate specific items, find chests, track NPCs, check world statistics, and modify tile layers or world properties (such as hardmode triggers, defeated bosses, and world name) without installing any software.
Yes, it is 100% safe. All file parsing, map rendering, and editing are executed entirely client-side inside your browser. Your Terraria world files are never uploaded to any remote server or database. Your privacy and save files remain strictly on your local device.
Usage
After making edits using the editor panels, click on the Data menu and select "Download World" or "Save Changes". This will generate and download a modified .wld file. You can then copy this file and overwrite the original file in your Terraria saves folder. Make sure to back up your original save file before replacing it.
Save folders depend on your operating system:
- **Windows**: Documents\My Games\Terraria\Worlds
- **macOS**: ~/Library/Application Support/Terraria/Worlds
- **Linux**: ~/.local/share/Terraria/Worlds
- **Android**: Android/data/com.and.games505.TerrariaPaid/Worlds (Requires a file manager with Android/data access)
- **iOS**: On My iPhone/iPad -> Terraria -> Worlds
Compatibility
Yes, this tool has built-in support for modded world files (.twld) generated by tModLoader. When you open a modded world, it will detect modded block IDs, modded items in chests, and modded NPC entities, allowing you to search and view them like vanilla items.
Yes! Terraworld.dev is designed with a responsive, glassmorphic layout. The editor toolbar, search panels, and analysis summaries adapt to mobile screens. However, since rendering a massive world map requires web-canvas memory, we recommend using modern mobile devices with good RAM or running the tool on a desktop/laptop for the best performance.
Troubleshooting
This usually occurs when your world file is from a version of Terraria that is either extremely old (pre-1.3) or a brand new game release whose file structures have changed. We constantly update our parser to support the latest version (including Terraria 1.4.4 and preparatory work for 1.4.5). If your file is corrupted, you can try loading the backup file (.bak) instead.
