# UNIVERSAL VTT

## WHAT IS UNIVERSAL VTT?

In the [Export](/guide/final-steps/exporting-your-map.md#the-export-window) window, you can choose the **Universal VTT** format. It will create a *.dd2vtt* file instead of a regular image. It embeds the image file in **PNG** format and stores some data that can be read by a Virtual Tabletop (VTT) like [Foundry](https://foundryvtt.com/), [Roll20](https://roll20.net/), [Arkenforge](https://arkenforge.com/), [Fantasy Grounds Unity](https://www.fantasygrounds.com/home/FantasyGroundsUnity.php), and many others. 

{% hint style="info" %}
*While the format is **.dd2vtt**, it is similar to **.uvtt** and can be read by softwares that ask for **.uvtt** files.* 
{% endhint %}

You'll find a list of VTTs that support the **Universal VTT** format on the official [Dungeondraft website](https://dungeondraft.net/), in the "**VTT Integration**" section. Some of them support it natively, some others need a plugin.

\
**Data stored in UVTT files:**

* Image (PNG)
* Walls
* Portals
* Caves
* Light sources
* Grid PPI

That format is very useful when you have a lot of [walls](/guide/all-the-tools/design-tab/wall-tool.md), [doors](/guide/all-the-tools/design-tab/portal-tool.md) and/or [lights](/guide/all-the-tools/effects-tab/light-tool.md) and you don't want to spend a lot of time to draw them again in your VTT. When you import your file, all of that is **instantly generated** according to your map.

*Depending on the VTT you use, it might look different.*

{% hint style="success" %}
**Pro Tip:** *Foundry VTT can automatically convert the embedded PNG file to a WEBP file to make it lighter.*
