Technical note

JPEG to STEP: what carries over and what does not

JPEG is made of pixels, so the conversion works in two steps: the image is first traced into vector outlines, and those outlines are then extruded to the height you set. The result is real geometry rather than a picture wrapped in a 3D file. Outline tracing is the mode to use here, because it returns closed shapes, and only a closed shape has an area to lift. How good the result is depends almost entirely on the JPEG going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

3D Workflow

From picture to 3D model

reaConverter traces JPEG images into outlines and extrudes them into STEP models, so a logo or a sketch becomes a 3D part in one run.

  • Each image is vectorized first, then extruded to the height you set in millimetres
  • Works best with logos, signs and line art: a photo has no clean outlines to follow
  • Apply the same height and tracing settings to every image in the batch
  • Keep unreleased designs and client models on your PC: nothing is uploaded

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.
