Create compressed ZIP files with our easy to use and free tool. Our tool lets you upload a STEP (STEP-File) file and compress and convert this file to a ZIP (ZIP Archive) file that you can then download and edit/use within your applications.
Here are 2 simple steps to convert your STEP to ZIP.
First click the "Upload..." button, select your STEP file to upload. Select any configuration options. When the STEP to ZIP conversion has completed, you can download your ZIP file straight away.
We aim to process all STEP to ZIP 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 STEP file you submit to us. The resulting ZIP file, once created is deleted 1 hour after upload and the download link will expire after this time.
Yes! Our STEP to ZIP 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 STEP conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

The STEP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STEP files are text-based formatted files containing one instance per line.
Although STEP files are widely supported by most CAD applications the 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 text storage of information the files can be quite large.
STEP files when imported will be converted to 3D geometry comprising vertices and faces. If the STEP file contains color information this will be converted where possible.

The ZIP file is one of the most common types of compressed file types available and is widely used to compress any file type and give great compression results leading to smaller file sizes. ZIP files were originally released in 1989 and over time the format has received many revisions.
ZIP archives can contain any number of folders and files and can use many different compression algorithms to perform the file compression, though DEFLATE is the most common one in use. The format has built in support in many operating systems including Mac OS and Microsoft Windows.
