Scaling 3D models is essential for 3D printing, manufacturing, game development, and architectural visualization. You might need to resize models to fit specific dimensions, prepare them for different output devices, or adjust them for real-world applications where precise measurements matter.
Use this tool when preparing models for 3D printing at specific sizes, creating miniatures or large-scale replicas, adjusting models for game engines with different unit systems, or when you need precise dimensional control for manufacturing, prototyping, or architectural projects.
Our tool offers two scaling methods: Multiplier scaling (scale by a factor like 2x or 0.5x) and Dimensional scaling (set exact measurements in centimeters or inches). Both methods support uniform scaling or independent axis scaling for maximum flexibility.
When 'Lock Aspect Ratio' is enabled, changing one dimension automatically adjusts the others proportionally, maintaining the model's original shape. Disable it if you need to stretch or compress the model along specific axes, though this may distort the appearance.
Our scaling tool supports GLB, GLTF, OBJ, STL, PLY, and USDZ formats. The scaled model is output in the same format as the input, preserving all materials, textures, and other properties while applying the new dimensions.
Simply click 'Select File' or drag and drop your file into the upload area. The conversion will start automatically and you'll be able to download the converted file once it's complete.
You can upload files up to 100MB in size. For most 3D models, this is more than sufficient. If you need to process larger files, please contact us for assistance.
Our conversion tools are designed to preserve quality as much as possible. However, some formats may have different capabilities. We use industry-standard algorithms to ensure minimal quality loss during conversion.
Processing time depends on file size and complexity. Most files are converted within 30 seconds to 2 minutes. Larger or more complex models may take longer.
Yes! This tool is completely free to use with no hidden fees, subscriptions, or limitations. You can convert as many files as you need without any cost.
Absolutely. We take privacy seriously. Your uploaded files are processed securely and automatically deleted from our servers after conversion. We never store or share your files.
