Here is our free-to-use STL to WEBP conversion tool that will take your 3D STL model file and convert it into a high-quality WEBP image file. If you wish to batch convert multiple STL files, our converter supports up to 20 files at a time, with a dedicated download link being provided for each image file once completed.
Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.
With our 3D model STL to WEBP converter, your STL file is uploaded, and a snapshot of the rendered model is created and saved into a WEBP image file format. If your STL model has any textures, you can include them with your STL file at the time of upload. Our tool will automatically determine if any additional files are required to render your STL 3D model.
Here are two simple steps to convert your STL to WEBP 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 WEBP conversion has completed, you can download your WEBP file right away.
We aim to process all STL to WEBP 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 WebP file is a next-generation image file format designed for the web. It allows large and highly detailed photographic-quality images to be stored using a very small file size, making it an ideal format for use by websites where bandwidth comes at a premium.
It's aim is to replace other photographic formats, such as JPEG, by offering similar levels of compression and quality while offering a superior reduction in file size. As well as storing static images, the WEBP format can also store animations, making it a great alternative to the traditional animated GIF format.
As the WEBP format is still relatively new, support for it is best found in modern image editing applications or those that benefit from regular updates.
Our tool will internally render your STL file and capture an image of the 3D render, which will be saved to a WEBP file using a high-quality setting, ready for you to download.
