How to Optimize 3D File Size for Superior AR Code Performance
Accelerate your AR initiatives and maximize business engagement by preparing your 3D models with Blender before uploading them to AR Code. Well-optimized 3D models guarantee a frictionless Augmented Reality experience that excites audiences, drives interaction, and strengthens your brand visibility.
For the ultimate mobile AR Code experience, your 3D content should load in under 10 seconds on any device. Given that a typical mobile internet connection delivers approximately 1 megabit per second, optimizing your files is crucial for retaining users and enhancing engagement rates.
Follow these actionable steps to compress your 3D files in Blender and deliver impressive AR experiences:
Step 1: Compress and Optimize 3D Model Textures
Start by reducing texture file size with an image editor. We recommend GIMP, a powerful open-source solution (https://www.gimp.org/downloads/).
Access your 3D model textures using the following method: .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 (we recommend 1024x1024 pixels or less): Image > Scale Image
- Export textures as *.jpg with a quality setting of 90 or lower to achieve optimal compression: File > Export as
- Update the textures in Blender, or edit your .gltf file using a text editor to change file references (for example, from ".png" to ".jpg")
- Save your optimized files for the next steps
Step 2: Streamline Your 3D Model Using Decimation in Blender
Reducing polygon count is essential for effective AR performance. Use Blender’s decimate modifier to simplify meshes, keeping visuals sharp and ensuring a smooth and speedy AR experience for your business customers.
- Import your optimized *.gltf file into Blender
- Select the meshes you want to optimize
- Apply the decimation modifier so each mesh has fewer than 50,000 faces for the best AR results. For static (non-animated) models, join several meshes together for easier optimization.
- Export your 3D model as a *.glb file and select “Apply modifiers,” but do not enable the “Compress” option at export
Your optimized 3D model is now ready to be uploaded to the AR Code platform, empowering your business with interactive AR marketing, dynamic training, and immersive visualization tools.
How to Upload a 3D File on AR Code for High-Impact Business AR Experiences
Ensure the greatest possible engagement and seamless AR Code performance by using 3D models that are 25MB or less. While larger files may look more detailed, they increase loading times and can negatively impact customer satisfaction.

Well-optimized files create fast, dynamic AR experiences critical for business marketing, sales, and training campaigns.

Quick Recap: Compressing and Optimizing for Business-Grade 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 (quality 90 or lower)
- Edit .gltf file paths as needed
- Save the optimized assets
Step 2: Decimate Meshes in Blender
- Import the modified *.gltf file
- Select mesh(es) to optimize
- Aim for under 40,000 faces per mesh and review AR rendering
- Tip: Join meshes if the model is not animated
- Export as *.glb, applying all modifiers
- Upload your file to AR Code
Optimizing your 3D models for Augmented Reality revolutionizes your company’s digital presence. With Blender and GIMP, you can produce eye-catching, highly interactive AR content for commercial marketing, online retail, industrial manufacturing, and smart education solutions. Consistently test your AR files to guarantee a smooth and engaging experience for every business scenario.
