How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a DAE from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your STL the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Drop a file, get a converted file.

About DAE and STL

DAE, COLLADA (Collaborative Design Activity)

DAE is the file extension of COLLADA, the XML-based 3D asset exchange schema Sony and the Khronos Group standardized in the mid-2000s (ISO/PAS 17506). It stores scenes, geometry, materials, physics, and animation as human-readable XML. COLLADA was the neutral interchange format of its era, used by Google Earth and SketchUp models and early game pipelines, before glTF took over that role. A great deal of legacy content still ships as .dae, which is why every major DCC tool keeps an importer.

How to open

Blender (File > Import > Collada), SketchUp, Cinema 4D, and MeshLab open DAE directly. macOS Preview and Xcode render .dae natively (SceneKit's editor format). Because it is XML, any text editor shows the structure.

STL, Stereolithography

STL is the lingua franca of 3D printing, every slicer (PrusaSlicer, Bambu Studio, Cura, Simplify3D) reads it. Files are unstructured triangle soup: no scene graph, no materials, no scale info, just vertices and triangles. The format is ancient (1987) and primitive but its simplicity is exactly why it's universal. Two variants: ASCII (human-readable, big) and binary (compact, what most software produces).

How to open

Every 3D printing slicer, every CAD/3D tool (Blender, FreeCAD, Fusion 360, SolidWorks, Tinkercad). Free viewers: ViewSTL, MeshLab, online STL viewers.

FAQ

Common questions

Is this DAE → STL converter really free?

Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert DAE to STL?

Legacy 3D scene and model exchange, especially SketchUp/Google Earth era content. 3D printing, feed an STL into your slicer to get G-code. The most common reason to convert is compatibility, STL works in places where DAE doesn't, or vice versa.

How do I open a DAE file in the first place?

Blender (File > Import > Collada), SketchUp, Cinema 4D, and MeshLab open DAE directly. macOS Preview and Xcode render .dae natively (SceneKit's editor format). Because it is XML, any text editor shows the structure.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
