Questions buyers actually ask
Are my files uploaded?
No. Decoding, mesh generation, validation and STL export run on your device. The site downloads its scripts and public samples; it never uploads your file.
Does this reconstruct a full 3D object?
No. Relief and lithophane map brightness to height or thickness. Silhouette and SVG extrude flat outlines. STL stores geometry only, with coordinates intended as millimeters.
Can I use WebP as well as PNG and JPG?
Yes, raster decoding accepts PNG, JPG and WebP. Prepared SVG has a separate vector path. Animated content and arbitrary image formats are not supported.
What should I check after downloading?
Open the STL in your slicer, confirm the intended dimensions in millimeters, inspect holes and isolated pieces, and choose orientation and printer settings. Automatic closed-mesh checks do not prove every thin detail will print.

The expert review
Image2STL scores 81/100 as a free browser utility for turning images and prepared vectors into shallow STL geometry. Its strongest evidence is accessible structure and technically healthy public pages, while its most material weakness is mobile ergonomics.
