Terraria Map Viewer: view your world map online

The Terraria Map Viewer reads the world file (.wld) in your browser and draws each tile as one pixel. You can see oceans, floating islands, biomes, the Dungeon, caves and the Underworld, and zoom and pan the map with a mouse, keyboard or two fingers. A Small world has 4,200 × 1,200 tiles, Medium has 6,400 × 1,800 and Large has 8,400 × 2,400.

Reading, unpacking, and rendering all run locally in a background thread in your browser. No server request transfers or stores your world, and you need neither an account nor a login. The viewer does not modify the file; it only reads it.

On Windows, worlds are in “Documents\My Games\Terraria\Worlds”; on macOS, in “~/Library/Application Support/Terraria/Worlds”; and on Linux and Steam Deck, in “~/.local/share/Terraria/Worlds”. For tModLoader, the “Worlds” folder is inside the “tModLoader” subfolder of the Terraria folder, so on Windows it is in “Documents\My Games\Terraria\tModLoader\Worlds”. On a rented server, you can find the world in the server's world folder, accessible through the file manager or FTP. Consoles and phones do not allow file access, so you cannot retrieve the .wld file from them.

The viewer reads worlds from Terraria 1.4.0.5 and newer, in all three sizes and all difficulty modes, including the special seeds Drunk World, For the Worthy, Celebrationmk10, The Constant, Not the Bees, Don't Dig Up, No Traps and Get Fixed Boi. For worlds from 1.3 or the first 1.4.0 versions, open them once in a current Terraria version and save them there. Player maps (.map) aren't supported; use the .wld file for the same world. For tModLoader, open the .wld file from its “Worlds” folder. The viewer does not read the additional .twld file where tModLoader stores Mod data, so content from Mods such as Calamity will be missing from the map.

Terraria's world generator creates the world from the seed text; this viewer does not recreate that process. Generate the world with your seed in Terraria or on a Terraria server (for example, using the -autocreate option), then open the resulting .wld file here. You'll see the exact map your game uses, including all ores, chests and biomes.

Under “Find on map”, the viewer lists the ores, gems and objects found in your world, such as Life Crystals, Life Fruits, Demon Altars and Shadow Orbs, with their counts. For example, the sample world contains 14,290 Copper blocks and 96 Life Crystals. Click an item to mark its locations. Adjacent ore blocks are grouped into a vein, and the six locations closest to the spawn point are listed. Use the search field to find other blocks. You can show Chests as a separate layer with their positions and names, but the viewer does not show their contents.

The world file contains every block, including places you've never visited. The viewer therefore shows chests, altars, the Dungeon and biomes without hiding spoilers. It only reads the file and doesn't write anything back, so it won't reveal the in-game map. If you want to discover Terraria without spoilers, wait until you know the world well before using it, or use it to view the map of a world you're planning for your server.

The viewer runs in phone and tablet browsers, and you can zoom the map with two fingers. However, the console and mobile versions of Terraria don't give you access to the .wld file, so get it from your PC or server. A Large world (8,400 × 2,400 tiles, around 12 MB) is read in the background and drawn in strips so browsers with size limits can display it. A Large world may still be too much for older phones with little memory.

The “Save as PNG” button exports the entire world map as an image without markers. Small and Medium worlds are exported at one pixel per tile, so a Small world is 4,200 × 1,200 pixels. A Large world is scaled down because it exceeds the image size limit.
