glTF vs OBJ
glTF and OBJ are both mesh formats, but they were designed for different eras. glTF is the modern, web-optimized standard with PBR materials and compact binary packaging, while OBJ is a simple, universally supported legacy format.

OBJ: universal legacy
Plain-text, read by nearly every tool, MTL materials.
For the web, pick glTF
glTF loads faster and renders materials better online.
When to choose each
Choose glTF / GLB for web, real-time engines and AR/VR, where performance and PBR materials matter.
Choose OBJ for simple, broad interchange between offline rendering and DCC tools.
Converting between them
Convert OBJ to glTF to modernize a legacy mesh for the web.
glTF supports embedded textures via GLB, while OBJ relies on separate MTL and image files.
