Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

What are GKO files?

What are OBJ files?

OBJ is a 3D model format created by Wavefront Technologies for its Advanced Visualizer software and now supported by almost every 3D application, which makes it one of the most common formats for exchanging models. A file of this type is plain text that describes the shape of an object: the coordinates of its vertices, the texture coordinates used for UV mapping, the surface normals, and the faces that join them into polygons. Named groups divide a model into separate parts. Colors and materials are not stored in the file itself but in a separate .mtl file that it refers to, with the texture images kept alongside. The format holds a static model only, with no animation, bones, or lights.
