How to Convert GLTF to OBJ — Quick & Free
Fast, instant GLTF to OBJ conversion. No signup required. Just drop your .gltf file and get .obj in seconds.
Batch Settings
Some metadata may not survive
Your GLTF file may contain glTF extras, extensions metadata. OBJ has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
La conversion de fichiers 3D est une étape fréquente dans de nombreux flux de travail numériques. Parmi les formats les plus couramment rencontrés, le GLTF (GL Transmission Format) s'est imposé pour sa légèreté et son efficacité sur le web, tandis que l'OBJ (Object File) reste un pilier pour sa simplicité et sa compatibilité universelle avec les logiciels de modélisation 3D. Passer de l'un à l'autre peut s'avérer nécessaire pour des raisons d'intégration logicielle, d'optimisation de scène ou de spécifications de projet. Notre outil est conçu pour faciliter cette transition, vous permettant de conserver la structure et les informations essentielles de vos modèles 3D. Que vous travailliez sur des visualisations architecturales, des prototypes industriels ou des expériences interactives, une conversion fiable est primordiale pour la continuité de votre travail.
- Archivage patrimonial (musées, monuments)
- Prototypage industriel (ingénierie, design produit)
- Publication scientifique (visualisation de données complexes)
Pour les professionnels francophones, notamment en Europe et au Québec, il est fréquent de voir des fichiers GLTF utilisés pour des présentations interactives en ligne et de devoir les convertir en OBJ pour des analyses plus poussées ou des rendus finaux dans des logiciels comme 3ds Max ou Blender, très répandus dans ces régions.
About GLTF to OBJ Conversion
Short answer: yes, you can convert GLTF to OBJ online for free, and quality is well preserved with the right settings. Just upload your .gltf file to CocoConvert, pick OBJ as the output, and click Convert. The whole process takes seconds.
Now for the details. glTF is an open 3D scene format designed for efficient web and real-time delivery. OBJ is a simple 3D geometry format supporting vertices, faces, and texture coordinates. Converting between these two formats lets you convert between formats quickly.
Full Name: GLTF uses GL Transmission Format, while OBJ uses Wavefront OBJ. Compression: GLTF uses Lossless, while OBJ uses None (uncompressed). Typical File Size: GLTF uses 100 KB–50 MB (JSON + separate binary), while OBJ uses 1–500 MB (text-based, large for complex models).
Your GLTF file is decoded and re-encoded as OBJ. Converting GLTF to OBJ maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

Frequently Asked Questions
Is GLTF to OBJ conversion free?
Yes. CocoConvert offers free GLTF to OBJ conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is GLTF to OBJ conversion?
Most files convert in 2–10 seconds depending on size. Large 3d model files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded GLTF file and the converted OBJ file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting GLTF to OBJ lose quality?
Converting GLTF to OBJ maintains high quality with CocoConvert's optimised encoder settings.
Can I convert OBJ back to GLTF?
Yes, CocoConvert supports OBJ to GLTF conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
