Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

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

Our JPG to STL image conversion tool comes with a set of options allowing you to fine-tune the details of how the 3D model is generated. Once you have selected a file, you will see a button, which you can click to reveal adjustable properties such as whether the tool should use a Heightmap or Extrude algorithm to create the 3D model. There are also properties to control the size and detail of the model.

Frequently Asked Questions

How can I convert my JPG file to STL?

First, click the "Upload..." button and select your JPG file to upload. Your JPG file will be uploaded to our servers. When the JPG to STL conversion has completed, you can download your STL file right away.

How long does it take to convert my JPG to STL?

We aim to process all JPG to STL conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the JPG to STL conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How is the 3D model generated from my JPG image?

Our tool uses a Heightmap process whereby the STL 3D model is created based on the luminosity of the individual pixels in your JPG image.

Is there a limit to the size of my image?

Yes, to ensure our tool converts the JPG image quickly and with a reasonable final file size, your tool will resize any image larger than 600x600 pixels.

File format information for JPG and STL

Extension	JPG
Full Name	Joint Photographic Experts Group
Type	Image
Mime Type	image/jpeg
Format	Binary
Opens With	Paint.Net, Photoshop

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 colors that are not perceptible to the human eye are discarded during the compression process. The removal of this color 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.

Extension	STL
Full Name	Standard Triangle Language
Type	3D Model
Mime Type	application/vnd.ms-pki.stl
Format	Text
Opens With	Blender, MeshLab, CAD Assistant, DAZ Studio

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modeling 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 flavors: 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.

Information for converting from JPG to STL

Our JPG converter will convert your JPG file to a 3D model using the Heightmap process, whereby 2D pixels, based on their luminosity, are converted into 3D space to create a full 3D STL model ready for download for further processing in your favorite 3D editing package or for printing on a 3D printer.
