What happens to the files you upload
Your STL is converted on this server and the STEP result is offered back to you. Your files are deleted days. Your models are only used to improve stl2step if you opt in which is explained below.
How to opt in when reporting
By default none of your geometry is used by stl2step for development. Pressing 👎 opens a menu for feedback. If you then press "Allow use of model for improving conversion and submit feedback" your model will be made available to stl2step for development purposes, but will not be shared, published, or printed. If you would rather report a problem without sending the model, use the Submit Feedback button at the top of the page instead.
No warranty
This is a bespoke tool. It can produce a STEP file that is wrong, incomplete, or that your CAD package refuses to open, and it can fail outright on a model it cannot handle. Check the result before you rely on it. Do not use output from this service anywhere a mistake would cost money or safety. The service is provided as-is, with no warranty and no guarantee of availability — it may be taken down, reset, or changed without notice.
Getting your data removed
Everything expires on its own. If you want something gone sooner — including a model you sent with a report — send me a feedback report or an email and it will be deleted.
