In the Export 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, Roll20, Arkenforge, Fantasy Grounds Unity, and many others.
While the format is .dd2vtt, it is similar to .uvtt and can be read by softwares that ask for .uvtt files.
You'll find a list of VTTs that support the Universal VTT format on the official Dungeondraft website, 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, doors and/or lights 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.
