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

Use our free and fast online tool to convert your PNG image or logo into a 3D 3MF model file suitable for sending directly to a 3D printer. To convert your PNG simply 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 3MF 3D model size.

FAQ

How can I convert my PNG file to 3MF?

First click the "Upload..." button, select your PNG file to upload. Select any configuration options. When the PNG to 3MF conversion has completed, you can download your 3MF file straight away.

How long does it take to convert my PNG to 3MF?

We aim to process all PNG to 3MF 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 PNG to 3MF 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 PNG to 3MF on ImageToStl.com?

Yes, of course! We do not store the PNG file you submit to us. The resulting 3MF file, once created is deleted 1 hour after upload and the download link will expire after this time.

Can I convert PNG to 3MF on Windows, Linux, Android, iOS or Mac OS?

Yes! Our PNG to 3MF 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 3MF, 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 generated 3MF model, however a white pixel will have a height that you specify once your PNG is uploaded. The tool has a useful option Invert Output which will 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 to 3MF 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 offers superior quality compared to Standard mode and is ideal for simple images such as logos and other simple shapes such as coins (see our Pokécoin example in the library tab).

In Extrude Color mode our PNG to 3MF tool behaves in a similar way to Extrude mode except the tool does not vary the height of the 3D generated 3MF model based on the pixel luminosity, rather it transfers the pixel color directly to the generated 3D model allowing for color logos to be generated  (see our Olympic logo example in the library tab).

Description

The PNG graphics file format is a commonly used format for storing 2D images which can be highly compressed by the use a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.

PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990's as a superior format to GIF. PNG files are generally used for company logos, icons and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image hence the PNG format being unsuitable for most digital photo content.

Description

3MF files are a modern 3D file format designed specifically for use with 3D printable models (additive manufacturing). It was designed to be the successor to the popular legacy STL format (also a common format in 3D printing) to overcome the limitations of that format.

The format of 3MF files is XML based that are compressed with the standard Zip file compression resulting in small, easily transferable files. The format supports 3D meshes along with associated materials and textures all contained within the Zip file.

3MF Notes

3MF files support material and color information. If your uploaded model contains color information our tool will attempt to save this in the 3MF file at the end of the conversion process. Texture information is not supported at this time.

Supported Features

  • Mesh geometry
  • Face and vertex colors

Unsupported Features

  • Textures
