Free Online STL to JPG Converter

Here is our free-to-use STL to JPG conversion tool that will take your 3D STL model file and convert it into a high-quality JPG 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.

Please note: Your STL file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted STL file before this time.

With our 3D model STL to JPG converter, your STL file is uploaded, and a snapshot of the rendered model is created and saved into a JPG 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.

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 JPG file is a compressed and highly efficient image file format whose aim is to store photographic-quality images using a fraction of the storage space compared to other lossy and non-lossy image compression methods available at the time.

The compression used by JPG encoders is "lossy", meaning image colours that are not perceptible to the human eye are discarded during the compression process. The removal of this colour data greatly reduces the size of the final JPG file with no discernible loss in quality.

Due to their compact and high-quality format, JPG files are one of the primary image formats used by websites, digital and phone/tablet cameras, and more. This widespread support means JPG files can be edited within most popular image editing software.

Information for converting from STL to JPG

Our tool will internally render your STL file and capture an image of the 3D render, which will be saved to a JPG file using a high-quality setting, ready for you to download.
