Free Online EPS to STL Converter

An EPS file, or Encapsulated PostScript to give it its full name, is a vector graphics file format aimed at the publishing and printing industries where high-definition graphics are paramount.

The format stores images in the form of lines, curves, shapes, and gradients to make up the final image. Unlike raster bitmap formats such as BMP, EPS is a vector format, meaning it can be scaled without any loss of detail or pixelation.

EPS files can be opened with a wide variety of vector editing applications, such as Inkscape; they can also be converted to bitmap formats, such as PNG, using our array of EPS conversion tools.

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.
