Image to STL

Convert your 2D PNG image file to a 3D STL model

Use our free and fast online tool to convert your PNG image or logo into a 3D STL model file suitable for printing with a 3D printer or for loading into your favourite 3D editing package. To convert your image simple click the Upload a file... button and select your image. Once selected you will be able to set various options to control the size of the generated 3D model size.

Click on the "Upload a file" button above to begin. Your PNG image/heightmap should fit within 600 x 600 pixels, if it is larger than this the image will be resized accordingly. Once you submit your image it will be processed as quickly as possible. More complicated images may take longer than others so please be patient. For more information about how your image is converted into the final 3D model please see the section below How Does it Work?.

FAQ

How can I convert my Image file to STL?

First click the "Upload..." button, select your Image file to upload. Select any configuration options. When the Image to STL conversion has completed, you can download your STL file straight away.

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

We aim to process all Image 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 Image to STL conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features being added every week.

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

Yes, of course! We do not store the Image 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 Image to STL on Windows, Linux, Android, iOS or Mac OS?

Yes! Our Image 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.

PNG 2D to 3D STL, How Does It Work?

Standard Mode (Heightmap)

In Standard mode our tool examines your 2D PNG image 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 PNG 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 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 PNG 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). We also have another version of this tool aimed at extruding images to color 3D models, this is only available to 3D file formats that support color such as 3MF.
