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 OFF, or download everything as one ZIP if you converted several files.
The GLB to OFF 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. OFF is a short, readable text file that geometry libraries and research code read directly. GLB is at home in sharing one self-contained 3D model for the web or AR; OFF is the usual choice for simple polygon meshes in research code and shape datasets.
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. 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 converterOFF lists a mesh as plain text: a header with the vertex and face counts, one line per vertex, then one line per polygon giving its corner count and vertex indices. Variants add vertex colours (COFF) or normals (NOFF). Its simplicity made it the format of shape benchmarks such as Princeton's and ModelNet.

No. The GLB to OFF 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: OFF 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 OFF. 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.
