Our free and fast tool will convert most 3D mesh or GLB (Graphics Language Transmission Format) model files to a standard ABC (Alembic) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple GLB files; up to 25 files at a time can be converted.
To convert your GLB file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a ABC file and will be ready for download shortly afterwards. For more information about the GLB to ABC conversion process, see the conversion information section below.

The GLB file format, which can also have the GLTF file extension depending on whether the content is binary or text/JSON, is a 3D file format used to describe 3D worlds and, as such, contains geometric data such as vertices, faces, normals, animations, and other 3D scene-related data.
The format, described by its creators as the "JPEG of 3D", has gained in popularity and is supported by a wide range of 3D modeling applications such as Blender and MeshLab. The GLB format is an open standard that is maintained by the Khronos Group.
If your GLB file contains texture files and other texture-related data, these will be included in the conversion process.

The ABC (Alembic) file format is a graphics format containing 3D content that was originally developed by Sony Pictures Imageworks and Industrial Light & Magic and released in 2011. The aim of the ABC format is to enable the efficient interchange of 3D assets between different working entities.
The format can contain a variety of 3D object formats, including polygon meshes, NURBS, parametric curves, and more. The files can be opened by many 3D graphics applications, including the popular open-source Blender application.
Converting from the GLB file format to ABC can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your GLB file to a valid ABC 3D model. Let's start with the conversion process, which involves the following steps:
In its simplest form, an GLB file is a binary data file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.
When our tool reads this 3D data, all we are interested in are the vertices, faces, and normals, as this is the only data that can be accurately converted into the final ABC file.
The GLB file can contain other data, such as material definitions and textures, that describe how a particular set of 3D geometry should be rendered. As we are creating an ABC file, which does not support materials and textures, we will be ignoring this data if it is present in the GLB file.
For more information regarding the GLB file format, please see this great article that goes into a lot of detail explaining the GLB format.
With the GLB file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the ABC format.
With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the ABC format.
Many 3D file conversion websites use the same off-the-shelf components to convert files, these often lack features and full GLB file compatibility. Our bespoke file conversion tools offer full GLB file compatibility and have been developed in-house by a team of developers, some of whom have over 30 years of experience working with 3D graphics file formats, meaning our tools will convert your GLB file quickly and accurately with maximum compatibility.
Yes! Our GLB tool supports full batch conversions. You can upload up to 25 and GLB files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the ABC files individually or download them all in a single ZIP file.
First click the "Upload..." button, select your GLB file to upload. Select any configuration options. When the GLB to ABC conversion has completed, you can download your ABC file straight away.
We aim to process all GLB to ABC conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the GLB file you submit to us. The resulting ABC file, once created, is stored for 1 hour after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.
No. All our conversion tools process your GLB file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted ABC file quickly.
Yes! Our GLB to ABC tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our GLB conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes. When you have converted your GLB to ABC, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
