How to convert RBXL to AMF
- 01
Add your .rbxl file
Drag your Roblox Place 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 .amf file
Press convert. The Additive Manufacturing Format 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 RBXL file becomes an AMF file.
| Data | RBXL | AMF | Survives |
|---|---|---|---|
| Geometry | Yes | Yes | Yes |
| Materials & colour | Yes | Yes | Yes |
| Texture maps | No | No | n/a |
| Animation & rigs | No | No | n/a |
| Scene hierarchy | Yes | Yes | Yes |
This is a comparatively lossless pairing: 3 of the five categories above are supported by both formats, so most of what is in your RBXL file has somewhere to go in the AMF file.
What our AMF writer puts in the file
Geometry, per-volume material colour and the unit, written as plain XML rather than the zipped form, because half the readers that claim AMF support take only the plain one.
About Roblox Place
A place file is an entire Roblox game world in the same container as a model file, and it converts the same way: every built-in part becomes geometry with its colour and transform, nested exactly as it was in the explorer. Places are large, tens of thousands of parts being normal, so expect a big mesh at the other end and consider running the result through the compressor.
Commonly seen in: Roblox Studio, Roblox game development. More on the RBXL format page.
About Additive Manufacturing Format
AMF is the ISO/ASTM standard that took the first run at replacing STL: XML-based, unit-aware, with support for graded materials, colour and curved triangles that subdivide smoothly instead of faceting. It largely lost the format race to 3MF in practice, but it remains the standardised choice and turns up in research and industrial additive-manufacturing workflows.
Commonly seen in: Slic3r, PrusaSlicer, Netfabb, academic and industrial AM tooling. More on the AMF 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 RBXL 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 AMF 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.
RBXL to AMF: common questions
Is my RBXL 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 RBXL 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 AMF file look untextured?
AMF 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.
