HOW IT WORKS

From canvas to usable file

  1. 1Choose a supported local Terraria .wld file; strict validation checks the required header, section directory, and bound footer before reading metadata.
  2. 2Review the embedded seed together with the world name, dimensions, difficulty, evil type, and supported file version.
  3. 3Copy the exact seed or open the related map viewer while the original .wld file remains unchanged on your device.

FAQ

FAQ

Is my Terraria world file uploaded?

No. A supported .wld file is read locally in your browser and is not sent to Visualiquid.

Which Terraria world files are supported?

The workspace supports standard Terraria .wld world-format versions 179 through 326. Other versions, modified layouts, sidecar mod data, and files missing viewer-required structure are rejected instead of being guessed.

What world information can the Terraria world seed viewer read?

For a supported file, it shows the embedded seed and the parsed world name, size, difficulty, evil type, and file version available in that format.

Does the Terraria seed generator predict a new world?

No. The auxiliary generator creates a seed value only; it does not simulate or predict Terraria terrain, structures, biomes, chests, or loot.

Will reading the seed change my world save?

No. The viewer does not write to the selected .wld file, and your original world remains unchanged.
