Open 3MF files online and inspect scene colors, overall dimensions and placement on the build plate.
glTF Validator
Check a glTF or GLB package for readable structure, declared local resources and supported mesh data before opening or converting it.
3MF Validator
Check a 3MF package for readable model entries, supported build items and mesh data before using it in a viewer or converter.
STL Viewer
Open binary or text STL meshes online to orbit, inspect dimensions and compare solid, edge and wireframe displays.
GLB Viewer
Open a GLB model online to inspect supported mesh data, materials, dimensions and display modes in an orbitable scene.
glTF Viewer
Open a glTF package with selected local BIN and image resources online, then orbit and inspect the resolved supported scene.
OBJ Viewer
Open an OBJ mesh with selected local MTL and image resources online, then orbit and inspect the supported resolved model.
PLY Viewer
Open a mesh or point-cloud PLY file online, detect its supported representation and inspect it with appropriate display controls.
Convert, simplify, optimize and create 3D models
Convert supported 3MF, GLB, OBJ, STL and mesh PLY data, clean GLB files, repair common mesh issues, simplify static meshes and create printable geometry from vectors or heightmaps.
OBJ to GLB Converter
Convert OBJ geometry to a compact GLB file online with scale and axis controls.
STL to GLB Converter
Convert binary or text STL meshes to GLB online and add a clean preview material.
GLB Compressor & Optimizer
Clean a GLB losslessly or apply an explicit balanced 16-bit geometry quantization, then compare the measured local result.
STL Repair & Printability Check
Clean up supported STL issues, then review duplicate points, degenerate faces, orientation and printability signals.
SVG to STL
Turn a filled SVG shape into an extruded STL model for badges, signs, cutters and simple parts.
Heightmap to STL
Convert a grayscale heightmap into a solid STL terrain tile or relief model.
3MF to STL Converter
Convert supported 3MF mesh geometry to STL while making the loss of package colors and other non-geometry details explicit.
3MF to GLB Converter
Convert supported 3MF parts to a GLB scene while retaining the supported colors and build placement that fit the result format.
Mesh Simplifier
Reduce supported static mesh complexity to a chosen target while showing measured triangle change, preserved bounds and any geometry kept intact for safe material or boundary handling.
GLB to STL Converter
Convert supported static GLB triangle meshes to a geometry-only STL result while making unsupported scene data explicit.
OBJ to STL Converter
Convert OBJ triangle geometry to STL online while making the loss of OBJ materials and image references explicit.
STL to OBJ Converter
Convert binary or text STL geometry to a simple OBJ mesh with explicit unit and normal choices for downstream editing.
PLY to STL Converter
Convert supported triangle mesh PLY files to STL while rejecting point-only and Gaussian splat content that cannot become a surface mesh.
Turn depth and photos into 3D
Build geometry from an existing depth map or explore the clearly labelled single-photo research preview.
Popular 3D formats supported by this collection
Start with the format that matches your model, scan, print job or image-based workflow.
Gaussian splat PLY, SPLAT, XYZ and PTS for orbitable scene and point-cloud review. Point-only data is not silently converted into a surface.
G-code, SVG and grayscale height or depth maps for paths, extrusions, terrain and surfaces.
Frequently asked questions
Answers about supported formats, private file handling and choosing a 3D workflow.
Which 3D formats can I open?
The collection includes tools for GLB, glTF, OBJ, STL, PLY, XYZ, PTS, 3MF, G-code, Gaussian splat files, SVG and image-based height or depth maps. Package checks distinguish selected local resource validation from visual viewing and conversion.
Are my 3D files uploaded?
Supported file contents stay on this device while the selected tool runs; site analytics and the assistant are separate.
How do I choose the right 3D tool?
Start with a validator when you need to check a glTF or 3MF package, a viewer when you need to inspect an existing file, a converter when you need a different supported format, a repair, simplifier or optimizer when the source needs review, and a geometry tool when the input is SVG, height-map or depth-map data.
