How to convert SLDPRT to XYZ
- 01
Add your .sldprt file
Drag your SolidWorks Part file onto the drop zone, or click it to browse. Nothing is uploaded: it is read where it already sits.
- 02
Check the preview
The model is parsed on your machine and drawn in the viewport, so a wrong axis or a missing texture shows up before you commit rather than downstream.
- 03
Save the .xyz file
Press convert. The XYZ Point Cloud file is written in the tab and lands in your downloads folder. No link, no expiry, no account.
What carries over, and what does not
A format conversion is a translation, and translations lose things. Here is what actually happens when an SLDPRT file becomes an XYZ file.
| Data | SLDPRT | XYZ | Survives |
|---|---|---|---|
| Geometry | Yes | No | Dropped |
| Materials & colour | No | No | n/a |
| Texture maps | No | No | n/a |
| Animation & rigs | No | No | n/a |
| Scene hierarchy | Yes | No | Dropped |
Expect to lose
- The scene hierarchy is flattened: separate objects in the SLDPRT file are merged into one mesh.
None of this is a defect in the conversion; it is what XYZ is specified to hold. If you need the missing data, convert to GLB instead, which carries geometry, PBR materials, textures and animation in a single file.
What our XYZ writer puts in the file
The vertices of the model, one point a line, with colour. Triangles are not written.
About SolidWorks Part
A .sldprt holds its solid twice over. The exact one is a Parasolid XT stream, a commercial kernel format that needs a NURBS engine to turn into triangles, and that is the part nobody can read. The other is the tessellation SolidWorks caches so it can draw a part in lightweight mode without rebuilding it, and that one is a mesh: per face, a list of triangle strips with float32 positions in metres, unit normals and texture coordinates. That is what we read. Files from 2014 and earlier are OLE2 compound documents whose larger streams are chains of zlib blocks; 2015 and later use a container of SolidWorks' own, with stream names written with the nibbles of every byte swapped. Both open here, along with the properties, the configurations and the preview image the file carries of itself. The mesh is at the deviation the part was saved with, which is the same surface SolidWorks shows you; if you need the exact analytic surfaces, export STEP.
Commonly seen in: SolidWorks. More on the SLDPRT format page.
About XYZ Point Cloud
An XYZ file is a text file with one point per line: three coordinates, optionally followed by three colour values. That is the entire specification. Its simplicity makes it the universal fallback for surveying data, scientific point sets and anything exported from a spreadsheet or a script.
Commonly seen in: CloudCompare, MeshLab, surveying tools, scientific data exports. More on the XYZ format page.
How the conversion works
When you drop a file in, the bytes are handed to a parser compiled to run in your browser. The SLDPRT data is decoded into an in-memory scene graph of meshes, materials and transforms, which is what the preview is drawing. Pressing convert walks that scene graph back out through a XYZ writer and hands you the resulting bytes as a download.
The whole round trip is local. The page itself is static: it is delivered once and then does its work offline. That is why the privacy claim is checkable rather than a promise.
SLDPRT to XYZ: common questions
Is my SLDPRT file uploaded anywhere?
No. The file is read by code running inside this browser tab and never crosses the network. You can prove it by disconnecting from the internet before you convert, the page keeps working, or by watching the Network tab in your browser's developer tools while you drop a file in.
How large an SLDPRT file can I convert?
There is no server-side limit because there is no server. The practical ceiling is your own machine's memory: a browser tab can usually handle models up to a few hundred megabytes. Very dense scans or scenes with millions of triangles will take a few seconds and a lot of RAM.
Why does my converted XYZ file look untextured?
XYZ stores geometry only; it has no way to record materials or texture maps. If you need the surfacing to survive, convert to GLB or glTF instead.
Does it cost anything?
No. There is no fee, no account, no watermark and no per-file limit. Since the conversion runs on your hardware rather than ours, serving this page costs about as much as serving a blog post.
Does it work on a Mac, on Windows or on a phone?
All of them. There is nothing to install: any browser with WebGL 2 will do, which covers current Chrome, Edge, Firefox and Safari on desktop, and Safari and Chrome on mobile. A phone has less memory than a laptop, so a very heavy scene may be the one thing it cannot finish.
