This is our fast and free file converter, specializing in converting your STEP 3D model files. You can convert your STEP files to a number of different formats, whether that be another 3D model format or an image. Our STEP converter can handle the most popular formats. Our STEP converter can also batch process up to 20 files at a time.
Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.
To start, please click the button above and select the 3D model STEP files you wish to convert. Once you have selected these, you can specify what you would like each file to be converted to. This could be another 3D model format, or another format from our extensive list. Once the target formats have been set, you can apply any configurations (such as applying the built-in voxelizer) by clicking the button.
Here are 3 simple steps to convert your STEP file using our fast and free STEP file converter tool.
Yes! Our STEP conversion tools are 100% free to use.
No, you can convert as many files as you wish. We do not impose any conversion limits on our STEP conversion tools.
We aim to process all STEP conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files and significantly longer for some larger file formats, so please be patient.
Once your STEP file has been uploaded and we know the file format you wish to convert it to, our bespoke conversion software will convert your STEP and make it available for you to download with a unique download URL.
Yes, of course it is! Your STEP, once converted, is deleted 1 hour after upload, and the download link will expire after this time.
Yes! Our STEP conversion tools will run on any system with a modern web browser.
If you are having difficulty converting your STEP, you can contact us, and we will try to help where possible.

STEP files are a 3D file format used to store complex 3D object definitions in a standard format to facilitate data transfer between compatible 3D modeling and CAD (Computer Aided Design) applications. In addition to storing 3D object data, the STEP format can store additional information such as materials, tolerances, and other relevant data.
The STEP format was first released in the early 1990's, has become a standard for 3D object storage, and is used in automotive, electronics, and other industries. STEP files can be opened in most modern CAD applications and can be imported into many 3D modeling applications too.
The file content is ASCII text-based and conforms to the ISO-10303-21 standard. The 3D object contained within the STEP file is described using a combination of points, lines, and edges. Due to the format being ASCII text, complex objects can lead to large file sizes. In addition to large file sizes, some complex STEP files can take a long time to open within editing applications, even on a high-spec, modern computer.
STEP Converter Capabilities
Our STEP converter can both convert from and to STEP files, and our developers are working to improve our STEP conversion tools in future versions. When converting 3D model or mesh files using our STEP converter, we will attempt to convert color materials into a suitable format for use in the converted file.
