Convert FBX to PLY
Free FBX to PLY converter that runs in your browser. See real dimensions before you download.
How to convert FBX to PLY
- Drop your FBX file (with its textures, if separate) onto the converter — it opens in your browser, nothing is uploaded.
- Check the preview and the dimensions in mm; fix units or the up axis in “Units & orientation” if the size or orientation looks wrong.
- Choose PLY as the output and click Convert. Several files download as one ZIP.
What carries over from FBX to PLY
| FBX | PLY | Result | |
|---|---|---|---|
| Colour / materials | Yes | Yes | Kept |
| Textures | Yes | No | Dropped |
| Units stored in file | Yes | No | Numbers in mm |
| Separate parts | Yes | No | Merged into one mesh |
| Usual up axis | Y | Z | Rotated (switchable) |
About FBX files
FBX began as Filmbox, a motion-capture tool from Kaydara, and Autodesk bought it in 2006 and kept developing it as a proprietary format. It has no public specification; the supported way to read or write it is Autodesk's FBX SDK, and other tools rely on that SDK or on reverse-engineered code. There is a binary encoding and an older ASCII one. FBX is more than a mesh container: it stores scene hierarchies, materials, cameras, lights, skeletons, skinning weights and animation takes. For that reason it became the usual bridge between modelling and animation packages such as Maya and 3ds Max and game engines such as Unity and Unreal. Scale and axis conventions vary by exporter, with centimetres being the common default, so an FBX can look wrong in a different program until the unit and up-axis settings are checked.
About PLY files
PLY was developed in the mid-1990s by Greg Turk and colleagues at the Stanford Graphics Lab to store data from 3D scanners, and the Stanford Bunny and Happy Buddha models made it famous. A PLY file starts with a text header that declares elements, such as vertex and face, and the properties each element has. The body then follows in ASCII, binary little-endian or binary big-endian. Because properties are declared in the header, a file can carry any extra per-vertex data: normals, colour channels, intensity, confidence or custom scalars. This flexibility made PLY a standard output for scanners, depth cameras, photogrammetry and point-cloud tools. It can store a point cloud with no faces at all, or a polygon mesh. It does not define units or a scene structure.
3D printing notes
Slicers do not take FBX, so the file has to be converted to a mesh format first. Animation and rigging are irrelevant to printing, so only the posed geometry matters. Many FBX models are in centimetres, which means a character that is 18 cm tall in the file must end up as 180 mm; reading it as millimetres gives 18 mm, and reading it as metres gives a huge model. MeshShift defaults FBX to centimetres, shows the real dimensions, and lets you change the unit. It reads FBX but does not write it, so a typical path is FBX to STL or 3MF, followed by the print check to close holes between separate body parts.
Frequently asked questions
Is this FBX to PLY converter free and private?
Yes. The conversion runs in your browser with JavaScript and WebAssembly, so your FBX file is never uploaded to a server. There is no sign-up, no watermark and no daily limit; very large files are limited only by your device's memory.
Why is FBX not accepted by Bambu Studio or PrusaSlicer?
Slicers need a plain printable surface, and FBX is built for animation and scene data, with a proprietary structure that requires Autodesk's SDK. They accept STL, OBJ and 3MF instead. Convert the FBX to one of those, keeping the posed geometry.
Does PLY store colour?
Yes, usually as red, green and blue values attached to each vertex, not as a texture image. Colours are smooth across triangles, which suits scans. Many slicers ignore vertex colour, so use 3MF or another format if you need to preserve it for printing.
