PNG to STL: Turn 2D Images into 3D‑Printable Models

PNG to STL conversion means turning a flat 2D raster image (PNG or JPG) into a 3D mesh file (STL) that a slicer can understand. The PNG stores pixels, while STL stores triangles in 3D space. Since PNGs don’t contain depth information, the converter has to infer height, thickness, and shape from brightness and edges.

You can upload PNG and JPG image files up to 10MB. For the cleanest PNG‑to‑STL conversion, use high‑resolution images with strong contrast, simple shapes, and clearly defined edges—especially for logos and icons.

Most PNG‑to‑STL conversions complete within a few minutes, depending on the complexity of your image. After upload, we process the image, generate a 3D mesh, and prepare an STL file that you can download and open in your slicer.

You can upload and preview images without an account, but you’ll need to sign in to start a conversion job and download your STL files. Creating an account also lets you save and revisit previous PNG‑to‑STL conversions.

High‑contrast PNGs with clean silhouettes, logos, simple line drawings, and text designs usually produce the best STL results. Complex photographs can be converted, but they may require extra cleanup and are better suited to bas‑relief or decorative prints rather than precise mechanical parts.

Yes. You own the rights to the STL files generated from your own images. You can use them for personal or commercial 3D printing projects such as custom merch, signage, keychains, or prototypes—subject to any rights on the original artwork you upload.

If your PNG‑to‑STL result looks too flat or like a single solid block, it usually means the image had low contrast or the inferred depth range is too small. Try increasing contrast in the original PNG, simplifying the background, or experimenting with a bolder, higher‑contrast version of your artwork.
