A .ply file is the Stanford Polygon File Format: a short header declaring elements and properties, followed by ASCII or binary vertex and face records. It remains a common interchange for scanned point clouds and triangle meshes in research and geometry processing.

Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.
Where PLY comes from
Greg Turk and colleagues at Stanford introduced PLY in the mid-1990s for the Digital Michelangelo Project and related range-scanning work. The simple header-plus-payload design spread through MeshLab, PCL, and academic toolchains even as glTF and 3MF grew in product workflows.
How PLY works
Header begins with ply and a format line (ascii 1.0 or binary_little_endian 1.0) and ends at end_header.
element vertex and element face blocks declare counts; vertices typically expose float x y z properties.
Faces commonly use property list uchar int vertex_indices and may be triangulated from n-gons.
Binary payloads pack scalars in little-endian order immediately after the header bytes.
When to use PLY
Exchanging scanned or remeshed triangle surfaces with research tools
Feeding MeshLab, CloudCompare, and geometry-processing scripts
Archiving simple meshes without materials
Converting between PLY and print or realtime mesh formats
Strengths and limitations
Strengths
Simple, extensible header that is easy to parse
ASCII and binary variants cover debugging and compactness
Long-standing support in mesh-processing software
Limitations
No standard materials, units, or scene graph
Big-endian and exotic property layouts are inconsistently supported
Compatibility
MeshLab, Blender, Open3D, PCL, and many academic converters read ASCII and little-endian binary .ply. CAD and slicer support is thinner than STL or 3MF, so conversion is common before printing or realtime use.
