Create compressed ZIP files with our easy-to-use and free tool. Our tool lets you upload a STL (Standard Triangle Language) file and compress and convert this file to a ZIP (ZIP Archive) file that you can then download and edit or use within your applications.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.
There were several formats that attempted to extend the STL format, namely SolidView and VisCAM, whose formats included limited 15-bit color information for each mesh face, which is often ignored by most modern 3D software. The STL format can be either text or binary; our tools will support both formats.
Standard STL files do not contain material or color information, so this cannot be imported. There are, however, two formats (VisCAM and SolidView) that attempt to add color information to the STL file format. If our tool detects this additional color information, it will attempt to import this information.

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 undergone 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.
You can convert from both text and binary STL files. If your STL file contains color information we will bring this over.
Many 3D file conversion websites use the same off-the-shelf components to convert files, these often lack features and full STL file compatibility. Our bespoke file conversion tools offer full STL 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 STL file quickly and accurately with maximum compatibility.
Yes! Our STL tool supports full batch conversions. You can upload up to 25 and STL files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the ZIP files individually or download them all in a single ZIP file.
First click the "Upload..." button, select your STL file to upload. Select any configuration options. When the STL to ZIP conversion has completed, you can download your ZIP file straight away.
We aim to process all STL 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 STL file you submit to us. The resulting ZIP file, once created is deleted 20 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your STL 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 ZIP file quickly.
Yes! Our STL 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 STL 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 STL to ZIP, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
