Visualize Your Container Loading in 3D
Intuitive packing previews that save time, space, and shipping costs.
Try It FreeCargoMax is a free, web-based 3D container loading calculator designed for shippers, freight forwarders, and e-commerce businesses. Unlike traditional spreadsheets or generic packing tools, we combine a powerful backend algorithm with a real-time 3D visualizer, so you can see exactly how your cargo fits inside a container.
Our tool supports multiple container types (20ft, 40ft, 40ft HC, and custom dimensions) and allows you to input pallets, cartons, or irregular items. Within seconds you receive a detailed packing plan, volumetric weight estimates, and an interactive 3D scene that you can rotate, zoom, and inspect. No downloads, no sign-up – just instant results. Whether you're planning a full container load or simply checking if your shipment will fit, CargoMax helps you reduce wasted space, cut shipping costs, and avoid unpleasant surprises at the warehouse.
Why CargoMax
Everything you need to plan your container loading with confidence.
3D Visual Preview
Unlike text-only calculators, our interactive 3D view shows exactly how each item is placed inside the container. Rotate, zoom, and confirm your load plan before it leaves the dock.
Instant, Accurate Results
Built on a battle-tested Express API, our engine returns space utilization, item count, and placement coordinates in under two seconds. No more manual sketches or spreadsheet guesswork.
Mobile‑Friendly & Free
Use CargoMax on any device — from a desktop in the office to a smartphone on the warehouse floor. The interface adapts perfectly, and the tool will always remain free for basic load planning.
How It Works

Enter Container & Cargo Details
Choose a standard container size or define your own dimensions. Add each item's length, width, height, and quantity.
Hit “Calculate”
Our API instantly processes your input using proven 3D bin-packing algorithms. No page reloads – the result appears right below the form.
Explore the 3D Visualization
Spin, zoom, and pan around the loaded container. Click on individual items to see their position and dimensions.

Download a screenshot of the 3D view or copy the text-based packing list. Use it for warehouse staff, shipping documents, or customer verification.
Frequently Asked Questions
Got questions? We've got answers.
A tool that automatically determines the best way to pack cargo into a shipping container, maximizing space while respecting weight limits and stability constraints.
No. CargoMax runs entirely in your web browser. There’s nothing to download, and you don’t need an account.
Yes, the packing calculation is performed on our server for speed and accuracy, but we do not store any of your input data after the calculation is complete.
We support 20ft, 40ft, 40ft High Cube, and custom containers. You can define the internal length, width, and height.
The current version works best with rectangular boxes and pallets. We recommend approximating irregular shapes as bounding boxes for planning purposes.
Yes, the 3D scene is built directly from the calculated coordinates. What you see in the preview exactly matches the placement data.
Absolutely. The basic tool is free to use. We may offer premium features (like API access or advanced constraints) in the future, but the core calculator will stay free.
Most tools give you only numbers. CargoMax combines a robust calculation engine with an interactive 3D view, so you can visually verify your load plan — a feature usually reserved for expensive desktop software.
