Our STL to ZIP file converter will take your uploaded STL file and compress it into a ZIP file, making it ideal to store or transmit your files while using less storage space and bandwidth. Our batch STL to ZIP converter can compress multiple files in a single upload. The maximum number of files that can be compressed in one go is 20.
Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.
Use the button above to select the STL files you wish to upload; once selected, you can click the Upload button to start the conversion. Once all your files have been converted, you will be able to download your ZIP files either individually or all together in a compressed ZIP file.
Here are two simple steps to convert your STL to ZIP using our fast and free STL converter tool.
First, click the "Upload..." button and select your STL file to upload. Your STL file will be uploaded to our servers. When the STL to ZIP conversion has completed, you can download your ZIP file right away.
We aim to process all STL to ZIP conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.
We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.
STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.
The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.
STL Converter Capabilities
When converting 3D model or mesh files using our STL converter, we will attempt to convert colour materials into a suitable format for use in the converted file.

A ZIP file is a compressed file container format that has been around for many years and has become a universal standard for compressing multiple files into a single package. Along with compressing individual files, ZIP files can also compress entire directory structures.
The compression algorithm of the ZIP format enables highly efficient compression of most file types, whether they be text, music, or images. ZIP files are a great way to group together and compress multiple files for easy storage and distribution.
As ZIP files have become a standard format for file compression, most operating systems and platforms are capable of creating and opening ZIP files without any additional software.
Our STL file converter will compress your uploaded file to a ZIP archive, ready for download. This tool is great for compressing those large STL files and saving yourself some hard drive space. ZIP archives can be opened later on in most operating systems, usually with no additional software.
