Our free and fast tool will convert your 3D STPZ (Compressed STEP-File) model files to a standard DXF (Drawing Exchange Format) file that can then be edited further in most popular 3D editing packages or 3D printed without any further processing. Our conversion tool can also batch convert multiple STPZ files; up to 200 files at a time can be converted.
To convert your STPZ file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a DXF file and will be ready for download shortly afterwards. For more information about the STPZ to DXF conversion process, see the conversion information section below.

The STPZ file format is a compressed version of the STEP file format, which is a 3D format defined in 1994 and used to store 3D objects for use in computer-aided design (CAD) applications. STPZ files are compressed binary files that, when decompressed into text format, contain one rendering command per line.
Although STEP files are widely supported by most CAD applications, there are only a few that support STPZ files. As with the uncompressed STEP version, the STPZ format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents, and due to the textual storage of information, the files can be quite large.
DXF files, when imported, will be converted to 3D geometry comprising vertices and faces. If the DXF file contains color information, this will be converted where possible.

The DXF file format was first introduced in 1982 as part of Autodesk's AutoCAD software. DXF files were intended at the time to allow data interchange between AutoCAD and other CAD-related applications. The format has evolved over the years, with the most recent version coming in 2007.
DXF files can contain either text or binary content describing blocks, entities, objects, and other information using a "tagging" system. The DXF format is still popular today and can be opened with most popular CAD applications.
Many 3D file conversion websites use the same off-the-shelf components to convert files, these often lack features and full STPZ file compatibility. Our bespoke file conversion tools offer full STPZ file compatibility and have been developed in-house by a team of developers, some of whom have over 30 years of experience working with 3D graphics file formats, meaning our tools will convert your STPZ file quickly and accurately with maximum compatibility.
First click the "Upload..." button, and select your STPZ file to upload. You can also drag and drop your file onto the tool. Once your file is selected, you can set any configuration options. When the STPZ to DXF conversion has completed, you can download your DXF file straight away.
We aim to process all STPZ to DXF conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the STPZ file you submit to us. The resulting DXF file, once created, is stored for 4 hours after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.
No. All our conversion tools process your STPZ file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted DXF file quickly.
Yes! Our STPZ to DXF tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our STPZ conversion tool please consider white-listing our website. When an Ad Blocker is enabled there are some conversion limits and some settings may not be available when using our tools. Processing/conversion and download times will also be longer.
Yes. When you have converted your STPZ to DXF, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
