Image & asset specs
Exact sizes and formats for every image you can add across OmniLab, with live previews you can download.
Hand this page to whoever creates your artwork — it lists the exact size, shape, and format for every image across OmniLab. Every preview is generated live, so you can switch examples and download a starter PNG for each one.

Good to know
- Formats: use JPEG, WEBP, or PNG. For icons and the wheel pointer, use a PNG with a transparent background.
- File size: there's no hard limit, but keep files light so pages load fast.
- 3D objects (catcher, 3D selection, treasure hunts) aren't image uploads — you pick them from your 3D library, and they need a GLB file (plus USDZ for the best result on iPhone and iPad).
