A Terraria seed viewer shows you a world's map before you commit to playing it, and a map viewer does the same for a world you already have. They're two different jobs, and the tool you want depends on one thing: do you have a world file (.wld), or only a seed? Only a seed, use a seed-based viewer. Got a file, use TerraMap to look around, or TEdit if you want to change things. Everything below is as of November 2026.
Seed viewer, map viewer, or editor?
People use "seed viewer", "map viewer" and "world viewer" like they mean the same thing. They don't quite:
- Seed viewer: you type a seed and get a map back without ever creating the world.
- Map (world) viewer: you open an existing
.wldfile and explore it: zoom around, search for ores, chests and the dungeon. - Editor: opens the file too, but it can change and save it. That's a different risk level, and I'll get to it.
| Tool | What it does | Needs | Version support | Where |
|---|---|---|---|---|
| terraria.tools seed map | Seed map viewer | A seed, or a .wld file | Check it against your game version | Browser |
| TerraMap | Viewer: pan, zoom, search blocks and items, read chest contents | A .wld file | Its page doesn't list a version, so check that your world opens | Browser |
| TEdit (desktop) | Map editor: edits the map, chests, signs and world settings | A .wld file | Release 5.2.5 (2 November 2026) supports Terraria 1.4.5.8 | PC |
| TEdit web | Browser editor for Terraria maps | A .wld file | Check it opens your world | Browser |
The game itself has had hotfixes up to 1.4.5.8 on PC since 1.4.5 landed in January 2026, so a viewer that last updated in the 1.4.0 days is worth skipping. Plenty of old roundups still recommend those.
Seed only? Start with a seed viewer
If you're still choosing, terraria.tools takes a seed or a .wld file and shows you the map. If you haven't picked a seed yet, my lists of the best Terraria seeds and the secret seeds are where I'd start.
My advice: before you trust any seed viewer, generate the world for real once and check a landmark against the map. Dungeon side and the evil biome are quick ones. If they match, that's a good sign. If they don't, you've saved yourself an afternoon of planning around the wrong map.
Where your Terraria world file lives on PC
Worlds are .wld files. Where they sit depends on your system:
- Windows:
%USERPROFILE%\Documents\My Games\Terraria\Worlds. Paste it into the File Explorer address bar. - Mac:
~/Library/Application Support/Terraria/Worlds. In Finder, hit Cmd+Shift+G and paste it in. - Linux:
~/.local/share/Terraria/Worlds
The Steam Cloud catch
If that Documents folder is empty or doesn't exist, your worlds are probably in Steam Cloud. Terraria's Steam ID is 105600, so look in your Steam folder under userdata, then your user ID folder, then 105600, then remote. On Windows that's usually C:\Program Files (x86)\Steam\userdata\{YOUR_USER_ID}\105600\remote. Inside remote, open whichever folder holds your .wld files.
Whichever route you took, copy the file somewhere else before you open it in anything. I'd do that every time, viewer or not.
How to open your world in TerraMap
- Go to terramap.github.io.
- Spoiler-free: click the folder button and pick the folder that holds your world and your player's map files. You only see what your character has already explored.
- Everything: click Open World File, or drag the
.wldonto the page, and the whole map shows. That's the "I don't care about spoilers" option. - Pan and zoom, then search for blocks and items, and read what's inside chests.
The page says your files are read in the browser and not uploaded anywhere, though your browser might still flash an "Uploading" warning. Ignore it.
A few keyboard shortcuts I'd actually use: f opens a folder, o opens a world file, n and p step through the next and previous match, h highlights every match, x clears the highlights, d jumps to the dungeon, s jumps to spawn.
It doesn't say which game versions it supports. So if your world won't load after a fresh 1.4.5.x hotfix, that's the first thing to suspect.
TEdit: powerful, and it can hurt your world
TEdit is a map editor. It'll show you the map too, but it's built to change it: the map itself, chests, signs, world settings. Because it writes world files, a bad save can wreck one, so work on a copy. The latest desktop release, 5.2.5 from 2 November 2026, supports Terraria 1.4.5.8. It also handles tModLoader .twld files, so modded worlds are covered there. If you only want to look, TerraMap is the safer pick.
Terraria seed viewer on console or mobile
People ask about this for PS4, PS5, Xbox and Android. Short answer: no viewer reads a console or mobile world directly. Your one option there is a seed viewer, if you know the seed.
Spoilers and cheating
A full-map view of your own world turns Terraria into a different game. You'll know where every chest and shrine is before you've dug a tile. That's fine if you're doing a speedrun or planning a build, and it kills the exploring if you aren't. My rule is spoiler-free mode for a world I'm actually playing, full view for planning. On a server with other people, ask before using it.
