All The Best Terraria Map Viewers
Terraria map viewers are 3rd party programs used to explore Terraria maps. You can use these programs to zoom, pan, find ores and blocks, dungeons, chests and more. You can even check chests content, since they can find out what's in them.
Some of these tools such as TEdit allow you to edit and change many things in your Terraria world.
Terramap - The Terraria Map Viewer
Known as the best Terraria world viewer, TerraMap helps you to explore your map easily. You can either download their program, or use the Terramap online viewer . This last option is really useful if you want to explore your map in your browser while playing.

The Terramap shortcuts are available on their official documentation . There you can learn how to use Terramap, how to highlight and find NPCs.
Terramap is literally Chunkbase but for Terraria. You can use it as your main Terraria Seed Viewer, but you won't be able to edit things, where TEdit strength shows up.
Features
- See a map from a seed
- View the entire world map in real-time without revealing fog
- Search for specific items, chests, ores, and structures
- Highlight important locations like biomes, NPC houses and traps
- Export map as an image
- Web-based and cross-platform (works on Windows, macOS, and Linux)
TEdit - The World Editor
The best Terraria Map Editor is TEdit. You need to download it to use it. TEdit is really useful, you can basically use it as Paint, but for your Terraria world.
If you ever made a Terraria server, you may have wanted to change the difficulty of your world. You can change the difficulty of your terraria server with TEdit. Changing it on your server won't do anything in the first place if the world was generated with another difficulty. This is why you also need to use TEdit.
One of the most common usage of TEdit is to cleanse the Evil Biome. Many tools are available, you can add items, edit chests, remove sprites, remove corruption and much more ! The only downside is that you need to use your world file. Unlike Terramap, you can't just paste a world seed and use TEdit as a terraria seed viewer.

Features
- Map edit tool allowing terrain and structure changes
- Add, remove & move blocks, walls, and liquids
- Change chests content, NPCs, and other world entities
- Compatible with a lot of Terraria versions
- Find your world seed
TerraFirma
Less popular than the previous tools, TerraFirma is a basic world viewer. You can't use this tool online, but need to download it.
With TerraFirma, you can zoom, pan around your map and save is as a png. There aren't many more features to be discussed here, we highly recommend to use Terramap instead.
Features
- A map viewer that works offline, good for exploring worlds
- Allows searching for items, chests, and any specific terrain feature
- Highlights biomes, traps, and other world elements
- Renders amps in different styles
- Can generate and export high resolution map images
Terraria Map Editor
This program name is pretty self-explanatory. Terraria Map Editor is an online alternative to TEdit, but with less features. The creator was independent, but the site is now available from the TEdit github organization. This must mean they are now the site owners.
Features
- Allows world modification for terrain, buildings, and items
- Undo/redo functionality for safer world editing
- Enables block and wall painting for visual changes
MoreTerra
MoreTerra is mostly used to generate an image of your map. This program is useful to place markers on your world. This can be useful to precisely find chests containing specific items, such as weapons or anything.
Features
- Lightweight map viewer with quick world rendering
- Useful to search ores and chests locations
- Helps finding biomes and structures
- Saves map snapshots for reference
Conclusion
There are many map viewers for Terraria. What we recommend is to only use Terramap as your world explorer, to find chests, items or dungeons. And to use TEdit when you need to edit your world. This is particularly true when you want to change your world difficulty, or just cleanse Corruption or the Evil biome. The choice is now all yours !
