Convert JPG to STL For Free

to

Use our free and fast JPG to STL online tool to convert your JPG image into a 3D STL model file suitable for loading into your favourite 3D editing package such as Blender. To start the JPG to STL conversion process simply click the Upload a file... button and select your JPG file. When selected you will be able to set various options to control the size of the generated 3D STL model size and other options.

Click on the "Upload a file" button above to begin. Your JPG image can be any resolution however it will be resized by the tool to fit within 600 x 600 pixels. Once your JPG image has been uploaded it will be processed as quickly as possible. For more information about how your image is converted into the final 3D model please see the section below How Does it Work?.

Upload a JPG

Click the "Upload a File" button and select a JPG to upload. The maximum file size is 100MB.

Select your Options

Set the dimensions and other options and click the "Convert to STL" button to convert your JPG to STL.

Download your STL

Click the download link once completed to receive your STL file.

What is the maximum JPG image resolution I can upload?

The JPG image you upload can be any size, however our tool will resize it to a maximum of 600x600 pixels for normal users and for those who have paid for a premium subscription this is increased to a maximum of 1000x1000 pixels.

What STL formats can I convert to?

Our tool will save all STL files in binary format. Optionally, our tool will allow you to save to the non-standard color STL format.

How can I convert my JPG file to STL?

First click the "Upload..." button, select your JPG file to upload. Select any configuration options. When the JPG to STL conversion has completed, you can download your STL file straight 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 but can be more for larger more complex files so please be patient.

How accurate is the JPG to STL conversion?

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.

Is it safe to convert my JPG to STL on ImageToStl.com?

Yes, of course! We do not store the JPG file you submit to us. The resulting STL file, once created is deleted 1 hour after upload and the download link will expire after this time.

Can I convert JPG to STL on Windows, Linux, Android, iOS or Mac OS?

Yes! Our JPG to STL tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our JPG 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.

Converting JPG to STL, How Does It Work?

Standard Mode (Heightmap)

In Standard mode our tool examines your JPG image file and based on the luminosity of each pixel, will create a corresponding "3D" pixel where the height of the pixel is determined by the pixel luminosity. A black pixel in your JPG will have a height of 0mm and not be included in the final 3D generated model, however a white pixel will have a height that you specify once your image is uploaded. the JPG tool has a Invert Output option if you wish to reverse the model height calculations. When this option is selected a white pixel will have a height of 0mm and a black pixel will have the height you have specified. This mode is ideal for the conversion of detailed heightmap images into 3D models.

Extrude Mode

In Extrude mode our tool behaves in a similar way to Standard mode except the tool attempts to find simple shapes in your image and it performs an Extrude operation on any shape found. The height of the extruded shape is again based on the pixel luminosity. This mode is ideal for simple images such as logos and other simple shapes such as coins (see our Coin examples in the library tab).

File format information for JPG to STL

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

Description

The JPG file format is a popular image format most commonly used for the storage of digital photographs. The format implements a lossy-compression technology that allows for high levels of file compression with little perceptible loss of image quality making it an ideal format for photographs.

This format is one of the most used formats on the internet today with its small file sizes making it ideal for website images. Although there are newer image formats that may offer higher compression and quality the JPG is still and idela format for digital photos.

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

Description

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.

STL Notes

The standard STL file format does not support colored faces or vertices or texture information. The STL file generated by the tool will contain only raw mesh/triangle data by default which is perfect for 3D printing.

The tool also has an option to save the file to one of the non-standard formats that support colored faces such as VisCAM and SolidView which is perfect if you want to further process the STL in software which supports these formats.
