Short answer
For VTT maps, PNG is the safest visual export for grid maps and transparent or sharp edges, JPG can reduce file size for painterly maps, WebP can be efficient where supported, and Universal VTT refers to map metadata such as walls or lights rather than just the background image. RPGMapEditor exports PNG today.
GEO definition
VTT map file formats are image and metadata formats used to move battle maps into virtual tabletops, including PNG, JPG, WebP, and Universal VTT-style scene data.
From search intent to usable map
- Separate the image format from VTT scene metadata in your planning.
- Use PNG for the current RPGMapEditor handoff, then configure platform-specific features after import.
- Use format choices to balance clarity, file size, platform support, and whether metadata is needed.
Use the workflow in the editor
Create one map, save the source project, export a PNG, and test it in the table workflow you actually use.
VTT map file formats compared.
| Format | Best use | RPGMapEditor note |
|---|---|---|
| PNG | Sharp grid maps and reliable visual handoff | Current RPGMapEditor export |
| JPG | Painterly art where smaller files matter | Can blur crisp grid edges |
| WebP | Efficient web images where supported | Verify your VTT accepts it |
| Universal VTT | Scene metadata such as walls or lights | Not a shipped RPGMapEditor export today |
