Use our free and fast online tool to convert your STP (STEP-File) 3D model file into a PNG (Portable Network Graphics) image file ready to download. Once the model has been loaded, you will be presented with a real-time 3D rendering of the model, which you will be able to rotate, zoom, and pan into the perfect position prior to capturing a screenshot for download.
First click the "Upload..." button, select your STP file to upload. Select any configuration options. When the STP to PNG conversion has completed, you can download your PNG file straight away.
We aim to process all STP to PNG 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 STP file you submit to us. The resulting PNG file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our STP to PNG 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 STP 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.
Yes. When you have converted your STP to PNG, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.

The STP file format, which can also be found with the extension STEP, is a 3D format defined in 1994 and used to store 3D objects for use in computer-aided design (CAD) applications. STP files are text-based, formatted files containing one instance per line.
Although STP 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 textual storage of information, the files can be quite large.
PNG files, when imported, will be converted to 3D geometry comprising vertices and faces. If the PNG file contains color information, this will be converted where possible.

The PNG graphics file format is a commonly used format for storing 2D images, which can be highly compressed by the use of a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.
PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990s as a superior format to GIF. PNG files are generally used for company logos, icons, and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image, hence the PNG format being unsuitable for most digital photo content.
