How It Works

reaConverter offers the fastest, simplest solution for converting your JLS files into GLTF in seconds - all images processed on your PC for maximum privacy and speed.

3D Workflow

From picture to 3D model

reaConverter traces JLS images into outlines and extrudes them into GLTF 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

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.
