I edited a scan as OBJ — how do I return it to the scan pipeline?

This conversion, precisely: OBJ is the editing format, PLY is the pipeline's native tongue. Geometry returns unchanged; just remember any texture work stays behind, since the scan pipeline's PLY world speaks vertex data, not image maps.

Will the PLY be smaller than the OBJ?

Usually yes — binary PLY packs vertices tightly and sheds the .mtl and image files entirely. The exception is ASCII-targeted PLY, which can rival OBJ's size. For storage and pipeline transfer, the binary default is the compact choice.

Do I need to install software to change OBJ into PLY?

No. The whole conversion runs as a web page: the OBJ file is parsed by your browser, rewritten to PLY locally, and handed back as a download. There is no installer, no plugin and no desktop app in the loop.

What happens to textures, materials on the way from OBJ to PLY?

The PLY format cannot store textures, materials, so that data is dropped during the rewrite — the geometry itself is unaffected. If those features matter for the asset's next stop, pick a target format that supports them, or keep a copy of the original file.

Will the model look different after OBJ → PLY?

Geometry is re-exported as-is, so shape, scale and UV layout stay faithful. The only visible changes come from features the PLY format cannot express (textures, materials) — those parts of the material or setup are simplified to whatever PLY can store.

OBJ to PLY trades material scaffolding for attribute precision: the mesh ships without .mtl packaging but with PLY's per-vertex data model — exact normals, optional vertex colors — in the format that scanning and metrology ecosystems treat as home. Geometry is untouched; the audience changes.

What changes in the file

1
Texture images have no PLY home — models that relied on image maps come through uncolored
2
Vertex colors only carry if they existed as OBJ vertex colors, which is rare outside scan-editing workflows
3
The file set collapses: no .mtl, no images, one self-contained PLY
