How to convert your file
Review your settings
Choose the right mode, scale and detail. Processing runs in your browser.
Inspect and download
Rotate the preview, save the output and verify it in your next application.
How WEBP to STL works
The image decoder reads the first frame and converts it to PNG pixels before outline or heightmap processing. Sampling is limited to 512 points on the longest edge.
Compatibility and limitations
Layers and animation are not preserved. HDR images become display-range pixels; color is not stored in standard STL. This creates a relief or extrusion, not a reconstruction of hidden surfaces.
Get a more reliable result
Start with a clean source, choose dimensions appropriate to the intended use, and inspect the exported file. A successful conversion does not guarantee printability or automatic mesh repair. Read our detailed workflow guide for the decisions that matter.
Processing limits
Raster images: 20 MB and 24 million pixels. SVG: 2 MB. Image sampling is up to 512 points on the longest edge. Width 10–300 mm, proportional height 1–600 mm, depth 0.2–20 mm, relief base 0.5–10 mm.
One file at a time. Processing stops after 90 seconds. Files remain in browser memory, and no conversion upload is performed. Replacing a file clears the previous result. Closing the tab releases its working data.
Questions about WEBP to STL
What information changes during conversion?
Layers and animation are not preserved. HDR images become display-range pixels; color is not stored in standard STL. This creates a relief or extrusion, not a reconstruction of hidden surfaces.
How do I inspect the output?
Open STL output in the STL viewer, then verify the scale and geometry in your slicer. OBJ output can be checked in a mesh application.
