Convert YDR to STL (Free)
Also converts OBJ, GLB, PLY, USDZ, 3MF, DAE from the same file.
Runs in your browser. No upload, no signup, nothing to install.
Also from Innerscene: Circadian Lab, a free lighting calculator for room illuminance, melanopic EML, and glare.
How to convert YDR to STL
- 1
Open your .ydr file
Drag it onto the viewer above, or click "Open a YDR File". Files up to 200 MB open directly; the parse runs in a worker so the page stays responsive.
- 2
Pick Stereolithography in the Export menu
Click Export in the toolbar, then STL (.stl).
- 3
Download
The .stl is written in the browser and saved straight to your downloads folder. No queue, no email, no watermark.
What survives the conversion
A file conversion is a translation, and formats do not carry the same things. Here is exactly what moves from YDR into STL, and what does not.
| Geometry | Kept | Both formats store triangle meshes, so the shape transfers directly. |
|---|---|---|
| Colors and materials | Dropped | STL has no concept of color or materials, so the material colors in your YDR file are not written. The geometry is unaffected. |
| Textures | Dropped | STL does not carry texture images, so a textured model arrives in flat material colors. |
| Layers and structure | Dropped | STL is a single flat body with no layers or named parts. Everything merges into one object. If you need the structure, export to GLB, OBJ, DXF instead. |
| Units and scale | Dropped | STL stores no unit. Coordinates are written in meters, so set the import unit to meters if the destination asks. |
What the STL writer emits: Binary STL, one triangle record per face, positions written verbatim in meters.
The source: GTA V model (.ydr, .ydd, .yft) (.ydr, .ydd, .yft, .ytd)
A GTA V model as the PC release stores it (a .ydr drawable, a .ydd dictionary of them such as ped clothing, or a .yft fragment such as a vehicle): every mesh at its most detailed level, upright, in metres, with the diffuse textures from the model and from any .ytd shared with it.
The target: Stereolithography (.stl)
The universal 3-D printing mesh. Every slicer and every printing service takes it.
Opens in: Cura, PrusaSlicer, Bambu Studio, Meshmixer, any printing service.
Your file never leaves your computer
Both the YDR parser and the STL writer are JavaScript and WebAssembly running in your own browser tab. There is no upload step, no server-side conversion queue, and no copy of your file anywhere but your machine. That matters for drawings under NDA, for client work, and for anything you would not email to a stranger.
Free to Use, No Signup
There are no accounts and no watermarks on this converter. If it saved you time, the one thing we ask is a mention: a post, a link from your blog or course page, or a reply to someone asking how to open a file.

Frequently asked questions
▶Is this YDR to STL converter free?
Yes. No signup, no watermark, no per-file limit and no paid tier. Innerscene.
▶Is my YDR file uploaded anywhere?
No. The file is read with the browser file API and converted in the same tab. Nothing is sent to a server unless you explicitly click Share, which is a separate, opt-in feature.
▶Will my colors and materials survive the STL export?
STL has no concept of color or materials, so the material colors in your YDR file are not written. The geometry is unaffected.
▶Do layers and named parts carry into the STL file?
STL is a single flat body with no layers or named parts. Everything merges into one object. If you need the structure, export to GLB, OBJ, DXF instead.
▶Will the STL open at the right size?
STL stores no unit. Coordinates are written in meters, so set the import unit to meters if the destination asks.
▶How large a YDR file can I convert?
Up to 200 MB, and the ceiling adapts to how much memory your device reports. The conversion runs on your own hardware, so a desktop with plenty of RAM will handle more than a phone.
▶Can I convert STL back to YDR?
Yes, the other direction works too. Bear in mind that anything the first conversion dropped is not restored by converting back. STL → YDR
▶Which browsers does it work in?
Chrome, Edge, Firefox and Safari, on Windows, macOS, Linux, iOS and Android. No plugin and no extension.
