VIDEO TUTORIAL: How to compress / reduce the size of a 3D model in Blender (GLB, GLTF, DAE, FBX, OBJ...)?
Tutorials | 17/10/2025 |
Blender is a powerful, open-source 3D software trusted by creative professionals and businesses for producing 3D graphics, animations, and visual effects. Its flexible compatibility with popular file formats like GLB, GLTF, DAE, OBJ, ABC, USD, BVH, PLY, STL, FBX, and X3D turns Blender into an indispensable solution for businesses looking to streamline their 3D modeling, design, and AR project workflows.

How to Optimize 3D File Size for AR Code Performance
Accelerate your AR projects and enhance business engagement by preparing your 3D models with Blender before uploading to AR Code. An optimized 3D model ensures a seamless Augmented Reality experience that captivates audiences and keeps them engaged with your brand.
For the best mobile AR Code experience, your content should load in under 10 seconds on any device. A standard mobile connection delivers about 1 megabit per second, so keeping your files well optimized is essential for user retention and engagement.
Follow these proven steps to compress your 3D files in Blender for outstanding AR display:
Step 1: Compress and Optimize 3D Model Textures
Begin with an image editing tool to minimize texture file size. We recommend GIMP, a robust open-source program (https://www.gimp.org/downloads/).
Access your 3D model textures using this format: .gltf + .bin + textures:
- Import your 3D model into Blender
- Export your 3D model in .gltf + .bin + textures
- Open the texture files in GIMP
- Resize images for maximum efficiency (1024x1024 or smaller recommended): Image > Scale Image
- Export the texture images in *.jpg format at quality 90 or lower for the best compression: File > Export as
- Update the textures in Blender, or use a text editor to adjust your .gltf file for the new texture file types (such as changing ".png" to ".jpg")
- Save your optimized files for later steps
Step 2: Streamline Your 3D Model with Decimation in Blender
Reducing polygon count is vital for AR. Decimate unnecessary mesh complexity in Blender to maintain visual quality while rapidly enhancing performance.
- Import your optimized *.gltf file into Blender
- Select individual meshes you’d like to optimize
- Apply the decimation modifier to each mesh, keeping them under 50,000 faces for best results. If your model is not animated, multiple meshes can be joined and optimized together.
- Export your 3D model as a *.glb file by choosing “Apply modifiers” without enabling the “Compress” option.
Your 3D model is now ready for upload to the AR Code platform, unlocking interactive AR marketing, training, and visualization experiences for your business.
How to Upload a 3D File on AR Code for Business-Ready AR Experiences
To maximize audience engagement and AR Code efficiency, use 3D models that are 25MB or smaller. Larger files may have higher resolution but can result in slow load times or lower customer satisfaction. For detailed guidance, visit Uploading 3D models on AR Code, what File Size and Format?. Optimized files deliver faster, more compelling AR experiences crucial for business applications like marketing and training.

Quick Recap: Compressing and Optimizing for AR
Step 1: Compress 3D Model Textures
- Import your 3D model into Blender
- Export as .gltf + .bin + textures
- Open texture files in GIMP
- Resize images (to 1024X1024 or less)
- Export textures as *.jpg (resolution 90 or lower)
- Edit .gltf file paths if needed
- Save it
Step 2: Decimate Meshes in Blender
- Import the edited *.gltf file
- Select mesh(es) to decimate
- Target under 40,000 faces per mesh and check 3D rendering quality
- Tip: Join meshes if model is not animated
- Export as *.glb, using “Apply modifiers”
- Upload your file to AR Code
Optimizing 3D models for Augmented Reality transforms your business's digital strategy. With Blender and GIMP, you can quickly produce engaging, high-performance AR content for marketing, retail, manufacturing, and education. Always test your AR content to guarantee a smooth user experience across all scenarios.

Frequently Asked Questions
What is Blender and which file formats does it support for import and export?
Blender is an advanced open-source tool for producing 3D graphics, featured animations, and realistic visual effects. Its broad support for major 3D file formats such as GLB, GLTF, DAE, ABC, USD, BVH, PLY, STL, FBX, and X3D means businesses can efficiently exchange and reuse 3D assets across diverse platforms, including AR Code for digital experiences.
Why is it important to compress 3D models before uploading them to AR Code?
Compressing your 3D models before uploading them to AR Code is critical to delivering a fast, smooth AR experience for your business or customers. Smaller, optimized files promote shorter loading times and keep your audience engaged, supporting business success and ensuring every AR interaction is efficient and captivating.
What is the process for compressing a 3D file in Blender to optimize it for Augmented Reality display?
To quickly optimize a 3D file in Blender for Augmented Reality, compress the 3D model's texture images with tools like GIMP, reducing file size while keeping visuals sharp. Afterward, use mesh decimation in Blender to lower the polygon count but retain essential shape and appearance. This dual optimization strategy balances exceptional visual quality with high AR performance to elevate your business presentations.
What is the recommended file size limit for a 3D model on AR Code?
The best practice for publishing on AR Code is to keep your 3D models below 25MB. This limit ensures the AR experience runs quickly and reliably in any business context—supporting both customer-facing campaigns and internal applications like product visualization or remote training. For tips on scanning and launching AR Codes effectively, see this scanning guide.
