Use our free and fast online tool to convert your PNG image or logo into a 3D Wavefront OBJ model file suitable 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 before submitting to receive your final Wavefront OBJ file.
Here are 3 simple steps to create an OBJ file from a PNG file.
Click the "Upload a File" button and select a PNG to upload. The maximum file size is 100MB.
Set the dimensions and other options and click the "Convert to OBJ" button to convert your PNG to OBJ.
The PNG 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.
First click the "Upload..." button, select your PNG file to upload. Select any configuration options. When the PNG to OBJ conversion has completed, you can download your OBJ file straight away.
We aim to process all PNG to OBJ conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
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.
Yes, of course! We do not store the PNG file you submit to us. The resulting OBJ file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our PNG to OBJ tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our PNG 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.
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 in your Wavefront OBJ file. 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 OBJ models.
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.
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.

The OBJ file format originally created by Wavefront Technologies and later adopted by many other 3D software vendors is a simple text-based file format for describing 3D model/geometry. This data can include Vertices, Faces, Normals, Texture Coordinates and references to external Texture files.
As the format is text-based it is relatively straight-forward to parse by 3D modelling applications. A downside of the text-based format is the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.
Our tool does not currently support saving material or color information for OBJ files.
