What Is a PLY File?
The Polygon File Format, also called the Stanford Triangle Format, was designed at Stanford for storing 3D scan data. A PLY file is a header (which declares what properties each vertex and face carries) followed by the data itself in either binary (compact) or ASCII (human-readable) form.
Unlike STL, PLY can carry per-vertex colors, normals, and arbitrary custom attributes — which is why every photogrammetry and LiDAR tool writes it.
Who Uses PLY Files?
Photogrammetry and 3D scanning users (RealityCapture, Meshroom, Agisoft Metashape), LiDAR processing pipelines, researchers working with the Stanford 3D scanning repository, and tools like MeshLab and CloudCompare.
Common Use Cases
- Preview a photogrammetry reconstruction before cleanup
- Inspect a LiDAR scan or point cloud
- View a downloaded Stanford bunny / dragon / Lucy benchmark mesh
- Convert PLY to OBJ, STL, or GLB for downstream tools
- Generate a PDF snapshot of a scan for a report
Features
Open Instantly
Drag and drop a .ply file — binary or ASCII, scan or mesh, the viewer detects the variant from the header.
Point Clouds & Meshes
Renders triangulated meshes as solid surfaces and pure point clouds as point primitives.
Vertex Colors
Per-vertex red / green / blue attributes from photogrammetry tools load and render automatically.
3D Navigation
Orbit, pan, and zoom with mouse or touch to inspect the scan from every angle.
Convert to GLB
Export PLY as GLB for use in modern web viewers, AR, and game engines.
Convert to OBJ
Save as Wavefront OBJ for use in MeshLab, Blender, Maya, or 3ds Max.
Convert to STL
Export as STL for 3D printing a scanned object.
Export as PDF
Generate a snapshot PDF of the current view for reports or client decks.
Handles Big Scans
Tens of millions of points / triangles handled on a modern desktop browser.
Embed on Any Site
Add the PLY viewer to your website with a single iframe embed code.
Compatibility & Format Notes
Both binary and ASCII PLY files are supported. Per-vertex colors, normals, and triangulated faces all load. Polygonal faces with more than three vertices are triangulated on the fly. Pure point clouds (no faces) render as point primitives.

Your Files Stay on Your Computer
Your PLY files are parsed entirely in your browser. Nothing is uploaded, stored, or shared unless you explicitly click the Share button. Shared files are hosted for 90 days then deleted.
Frequently Asked Questions
▶Does the viewer support binary AND ASCII PLY?
Yes. The header is parsed first to determine which body parser to use — you don’t need to know which variant your file is.
▶Will my photogrammetry vertex colors render?
Yes. Per-vertex red/green/blue attributes are picked up automatically and used as vertex colors when the mesh has no material.
▶Can I view a pure point cloud (no faces)?
Yes. PLY files with vertex data but no face data are rendered as a point cloud. Very dense scans (tens of millions of points) may be slow on phones — desktop browsers handle them well.
▶Is this PLY viewer really free?
Yes, completely free. No signup, no watermarks, no file size limits on the viewer (the optional share-link feature has a 30 MB upload cap). Built by Innerscene as a tool for architects, engineers, and designers.
▶Are my files uploaded to a server?
No. All parsing, rendering, and conversion runs in your browser — nothing is uploaded, stored, or transmitted by default. The Share button is the only feature that uploads a file, and only when you explicitly click it.
▶Can I convert to another format?
Yes. Click Export in the toolbar to save as STL (3D printing), OBJ (Wavefront), GLB (glTF binary), or PDF (snapshot of the current view).
▶Can I embed this viewer on my own site?
Yes. Click Embed in the toolbar to generate a one-line <iframe> snippet you can paste into any HTML page. You can choose whether the embed shows the viewer’s toolbar.
