Drop GLB 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 OBJ, or download everything as one ZIP if you converted several files.
The GLB to OBJ 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.
GLB is binary, so you cannot read or edit it in a text editor. OBJ is read by nearly every 3D program and can hold UV coordinates and materials. GLB is at home in sharing one self-contained 3D model for the web or AR; OBJ is the usual choice for exchanging a mesh between 3D programs.
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. Textures are not carried over, a glTF that points at a separate .bin file cannot be read from a single dropped file, and Draco or meshopt compressed geometry is refused with a message asking for an uncompressed export. Vertex colours are written into the OBJ; materials and textures are not. Models up to 3,000,000 triangles are accepted.
GLB packs a glTF scene, its geometry and its textures into one binary file, so it can be shared, uploaded or opened in an AR viewer without any companion files. Most 3D viewers on the web and social platforms prefer it.

GLB converterOBJ 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

No. The GLB to OBJ 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: OBJ 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 GLB file, press Convert and save the OBJ. 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.
