Drop OBJ files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the glTF, or download everything as one ZIP if you converted several files.
The OBJ to glTF converter is part of this page and runs inside your browser. Your 3D models are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
OBJ has no animation or scene structure, and the model and materials are separate files. glTF is the open standard for real-time and web 3D. OBJ is at home in exchanging a mesh between 3D programs; glTF is the usual choice for 3D on the web and in real-time engines.
The model is converted as triangles: lines and points are dropped, positions are used as they are, and no axis conversion is applied, so a model that is Y-up in glTF and Z-up in STL, OBJ and PLY is written exactly as it was read. The .gltf is a single file with the geometry embedded in it, so no separate .bin file is needed. Models up to 3,000,000 triangles are accepted.
OBJ is a text format that lists vertices, texture coordinates, normals and faces, with materials in a companion .mtl file. It has no animation or scene hierarchy, but it is so simple that almost every 3D program reads and writes it.
Opens in Blender, Maya, 3ds Max, MeshLab and nearly every 3D program
OBJ converterglTF is called the JPEG of 3D. A .gltf file is JSON describing a scene, with meshes, materials, animations and cameras, usually pointing at a separate binary data file and texture images. Version 2.0, from 2017, is an ISO standard.

No. The OBJ to glTF conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
No further quality is lost: glTF stores the decoded audio exactly. The result is identical in content.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the OBJ file, press Convert and save the glTF. There is nothing to install.
Yes. Models up to 150 MB and 3,000,000 triangles are accepted; a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
