Free Online PNG to 3MF Converter

With our PNG to 3MF converter, you can effortlessly convert your PNG image file into a 3D heightmap model, which can then be loaded into your favourite 3D editing software. Our image to 3MF tool can batch convert up to 20 PNG files at one time and quickly turn them into 3D models.

Select File(s)

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

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

Our PNG to 3MF 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 PNG file to 3MF?

First, click the "Upload..." button and select your PNG file to upload. Your PNG file will be uploaded to our servers. When the PNG to 3MF conversion has completed, you can download your 3MF file right 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; however, this can be longer for certain files, so please be patient.

How accurate is the PNG to 3MF 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 PNG image?

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

Is there a limit to the size of my image?

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

File format information for PNG and 3MF

Extension	PNG
Full Name	Portable Network Graphics
Type	Image
Mime Type	image/png
Format	Binary
Opens With	Paint.Net, Photoshop

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.

The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.

One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colours down to 256 or 16 colours to help reduce the file size of the PNG.

Extension	3MF
Full Name	3D Manufacturing Format
Type	3D Model
Mime Type	application/vnd.ms-package.3dmanufacturing-3dmodel+xml
Format	Binary

The 3MF file format was created as a standard storage medium for 3D models for use within the area of 3D printing. A 3MF file will contain 3D model data stored within an XML-formatted document with additional assets such as image previews and material data. These files are wrapped up within a compressed ZIP file (using the 3MF extension).

The 3MF format was created in response to the constraints of the STL format, which is the most popular format for storing 3D printable models. Unlike the STL format, which can only store triangular information, the 3MF format can store mesh geometry along with material, units of measurement, and other relevant 3D printing information that is impossible to store within an STL file.

Storing the 3D data within a ZIP file container ensures the file size is kept to a minimum while making it easily extendable in the future. 3MF files are widely supported by 3D printing slicer software and are a common export option within 3D editing software.

Information for converting from PNG to 3MF

Our PNG converter will convert your PNG 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 3MF model ready for download for further processing in your favourite 3D editing package or for printing on a 3D printer.
