Copyright and attribution

Users must own or have permission to use every submitted image. Photo2STL does not grant permission to copy a protected character, product, sculpture, photograph, logo, or other work.

Copyright concerns

A rights holder may contact Melvin Global LLC with a clear description of the work, the allegedly infringing use, contact information, and a good-faith statement of authority. Because Photo2STL does not provide a public gallery or retained model library, content may already have expired before a notice is received.

Model attribution

Low-poly generation uses Stability AI's SPAR3D under the Stability AI Community License. High-quality generation uses TencentARC's Pixal3D, based on Microsoft TRELLIS.2, under their MIT licenses. Supporting models, including DINOv3, MoGe, NAF, BiRefNet, and the MIT-licensed transparent-background/InSPyReNet foreground extractor, retain their respective licenses. Photo2STL preserves the applicable notices in its inference installation.
