Free Online PNG to OBJ Converter

With our PNG to OBJ 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 OBJ 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 OBJ 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 OBJ?

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 OBJ conversion has completed, you can download your OBJ file right away.

How long does it take to convert my PNG to OBJ?

We aim to process all PNG to OBJ 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 OBJ 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 OBJ 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.

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.

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular colour, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.

Information for converting from PNG to OBJ

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 OBJ model ready for download for further processing in your favourite 3D editing package or for printing on a 3D printer.
