Free online STL viewer
Open and view a STL file directly in your browser. Rotate, zoom and inspect the mesh without uploading your model.
Choose one model and its textures or BIN files together. Maximum 100 MB total.
Drag to rotate · Scroll or pinch to zoom · Right-drag to pan
What to know before opening your file
View binary or ASCII STL files before opening your slicer. Rotate the part to inspect its silhouette, underside and visible gaps.
STL stores triangles, not reliable physical units or textures. Wireframe helps reveal tessellation, but this viewer does not repair holes or confirm a watertight mesh.
How to view a 3D file online
- Choose your model and any companion files from your device.
- Rotate and zoom to inspect the shape. Enable wireframe to examine the mesh.
- Reset the camera or change the background for a clearer view.
Questions about the 3D viewer
Are my files uploaded?
Model files are read locally in your browser. No account or credits are required. External model resources are blocked; include companion files in your selection.
Can this viewer check whether a model is printable?
It helps you inspect geometry visually, but does not validate watertightness, wall thickness or printability. Check those in your slicer.
