Free 3D File Converters
Convert common 3D file formats directly in your browser. No upload, no account, and every converter explains what data can be lost.
GLTF / GLB Converter Online — Pack or Unpack, No Upload
Convert GLTF to GLB or unpack GLB to embedded GLTF JSON in your browser. Free, private, no upload, built for web 3D assets.
Check first: Use single-file or embedded GLTF; external .bin and texture references are not supported in this beta
OBJ to STL Converter — Free, Browser-Side, No Upload
Convert OBJ files to STL format in your browser. Ideal for 3D printing. No file upload required. Supports single and multi-object OBJ files.
Check first: Confirm the final size in your slicer because STL does not store units
STL to OBJ Converter — Free, Browser-Side, No Upload
Convert STL files to OBJ format instantly in your browser. No upload, no account. Supports binary and ASCII STL. Free and private.
Check first: Check the model scale after conversion because STL has no unit metadata
GLB to OBJ Converter — Free, Browser-Side, No Upload
Convert GLB files to OBJ format online, free and private. All processing happens in your browser. No server upload. Ideal for importing into modeling software.
Check first: Animations, rigs, cameras, lights, and scene behavior will not survive as OBJ
Image to STL Converter — Free Heightmap Relief, No Upload
Turn any image into a 3D-printable STL heightmap relief in your browser. Adjust depth and resolution. Free, private, no AI, no upload.
Check first: Use high-contrast images; subtle photos often produce noisy reliefs
OBJ to GLB Converter — Free, Browser-Side, No Upload
Convert OBJ files to GLB (binary glTF) format in your browser. No upload needed. Great for web 3D, AR, and game engines.
Check first: Load the matching MTL workflow when material data matters; geometry-only OBJ files cannot invent materials
PLY to STL Converter — Free, Browser-Side, No Upload
Convert PLY mesh files to STL format in your browser for 3D printing. No upload required. Point cloud PLY files are not supported.
Check first: Make sure the PLY contains faces; point clouds without mesh connectivity cannot become STL here
SVG to STL Converter — Free, Browser-Side, No Upload
Extrude SVG paths into printable STL files in your browser. Adjust depth and scale. Free, private, no upload. Useful for logos and 2D designs.
Check first: Convert text to paths in your vector editor before uploading the SVG
