Unpack a GLB into a readable glTF file. It is converted in your browser, so the file never leaves your device.

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 glTF, or download everything as one ZIP if you converted several files.
The GLB 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.
GLB and glTF describe the same scene. GLB packs the JSON description, geometry and textures into one binary file, while glTF keeps the description as readable JSON, which you can open in an editor to inspect nodes and materials.
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. 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.
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 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 GLB 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 GLB 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.
