Trace a picture and turn it into a solid 3D-printable shape: a logo, a line drawing, lettering or a silhouette. Use PNG, JPG, WebP, GIF, BMP or SVG. Adjust the threshold until the shape is filled in cleanly, smooth the edges, remove specks, and set the size.
Make a solid shape, raise the artwork on a backing plate with a border and rounded corners, or cut a spray stencil. Your original picture is never uploaded: the tracing happens in your browser. For a photo with shades of grey, a lithophane is the better choice.
Drop the PNG on the page, move the threshold until the shape you want is filled in, set the size and thickness, and download the STL.
Yes. SVG works well because its outlines are already clean; set the size and choose a solid shape, a raised plate or a stencil.
The picture has noise or a textured background. Raise "Ignore specks", add a little smoothing, or clean the picture up first in the image editor.
A photo has shades rather than clear shapes, so it traces poorly. For photos, make a lithophane instead.
