Frequently Asked Questions

Can I use RapidCompact for free?

Yes, RapidCompact is available for free. See details in the pricing table.

What file types can I upload?

You can upload files in the following formats:

  • FBX
  • glTF (.gltf and .glb)
  • OBJ
  • PLY
  • STL
  • CTM


Formats that reference external files (such as OBJ) must be uploaded as a .ZIP file. In order to load the external files correctly, care should be taken to ensure that the paths to external files are relative. Within the Enterprise plan it is possible to also process models in CAD formats like STEP, JT and IGES.

Would you like to see another format supported? Let us know.

What is the upload file size limit?

The limit differs based on the subscription plan. For example, the free plan there is a limit of 500mb for file upload. Basic has the limit of 1 GB and Professional has the limit of 3GB

What are the output file types?

As a result of optimizing a model you will receive a glb file. Additionally, you can choose one out of the following formats to be outputted as well:

  • glTF (.gltf and .glb)
  • OBJ
  • PLY
  • USDZ
  • STL
  • CTM


Would you like to see another format supported? Let us know.

Can I preserve UV maps?

Yes, when using the CLI you can choose to preserve the UV maps. This feature is currently unavailable in the browser interface of the RapidCompact portal, but will soon be added.

Can I preserve Materials and Tiled Textures?

Yes, that is possible. Simlply choose the field “Preserve Materials & Tiling” in the second step of the optimization (Asset Simplification), as it was done in the picture below.

What is a RapidPoint?

RapidPoints are needed to run an optimization on the RapidCompact platform. One RapidPoint allows for one export of an optimized 3D model.
For more information on exports, see below What is an export.

What is an export?

We call the output of the optimization process an export. You can optimize your 3D models once and export it in multiple formats. With each optimization you receive the result with a complimentary glb-version and one file type of your choice. If you like to do more exports, for example for exporting to another format, you can use RapidPoints for the conversion to those additional formats.

Can I use RapidCompact with a REST API?

Yes, the use of our REST API is possible starting from the Basic package on. Check out how it works in the documentation.

Can I use RapidCompact as CLI?

Yes, we have on-premise options for enterprise clients. If you are interested in learning more, contact our team.

Can I purchase additional points if I exceed my monthly plan?

Yes, it is possible to purchase a package of additional points. The size of the available packages depends on your plan. For example, if you are in the Professional plan, you can purchase a package of (1 x 800) additional points or (2 x 800) or (3 x 800). See the pricing tables for more information on the different plans.

Also see How does the billing work for more information on how the billing of the plans works.

How does the billing work?

Your plan is monthly recurring (you can cancel it anytime for the next month). The date you signup is fixed and will remain tied to your account even if you upgrade the subscription. Your monthly points will reset always on the day of the month of your original signup date. If you upgrade during the month, there will therefore be only a partial billing for the next tier. E.g.:

You sign up on the 1st of January with a Basic subscription. On the 15th you decide that you would be better served with a Professional plan and upgrade. You will then be billed with the cost of roughly half the month at the Professional price point, minus the same amount of time at the Basic price point. Your monthly points are then at the Professional level, but any points you already used in that month (when you were still at Basic level) are still considered used. So, if you used 100 out of your 250 points at Basic level and then switched to Professional you now have another 700 (800 – 100) points left for the month. If you continue your subscription, they will reset on the 1st of February

Any additional points you purchase are independent of your non-free account status and will remain available unchanged as they are.

Can I change or quit my plan monthly?

Yes, all accounts are on a monthly basis. Please see the point How does billing work above for more info.

How do I cancel my subscription?

You can simply cancel your subscription by clicking “cancel plan”. You find this setting under “Profile & Settings”.

Where do I report bugs/issues?

You can report bugs and issues of all kind in our ticketing system. Click on “Get Support” (see image below) in the top right of the menu to find the ticketing system.
