Convert your PNG file to GLB

Use our free and fast online tool to convert your PNG (Portable Network Graphics) image or logo into 3D GLB (Graphics Language Transmission Format) mesh/model files suitable for printing with a 3D printer or for loading into your favorite 3D editing package.

How to Convert your PNG to GLB Online?

Here are three simple steps to create an GLB file from a PNG file.

Upload a PNG

Click the "Upload a File" button and select PNG to upload. The maximum file size is 100MB.

Select your Options

Set the dimensions and other options, and click the "Convert to GLB" button to convert your PNG to GLB.

Download your GLB

Click the download link once completed to receive your GLB file.

PNG to GLB Conversion Options

Tool

This setting allows you to specify how your PNG image is converted to an GLB model. The Extrude options will extrude your image into 3D space, while the Standard options will apply a heightmap process to your image.

Detail

The setting can be used to alter the detail of the final GLB model that is created. The default setting of Medium works well for most Extrude and Heightmap conversions, with the High setting recommended for highly detailed image files.

Add Base

This setting, when given a height of more than zero, will instruct the tool to add a solid 3D base to the final GLB model. The selected unit of measurement specifies the height of the base.

Remove Background

When this option is enabled, the tool will automatically attempt to make the background of your image transparent.

Specify Color

Manually specify your image background color rather than our tool trying to automatically work it out.

Color

If the tool is unable to identify the background and you know the background color, you can specify it here.

Tolerance

This value can be adjusted to control the background removal tolerance. The higher the value, the more background is removed.

A higher value is useful for creating smoother results if your image is anti-aliased.

Invert Output

When the Invert Output option is checked, the pixel brightness is reversed, i.e., black becomes white and white becomes black, resulting in a 3D model that is reversed.

Units

This setting tells the tool how to size the final 3D model when using the settings below for Width, Height, and Depth settings.

Upload Color Overlay

When using either the Color Extrude or Heightmap options within the Tool menu, you can optionally upload a separate image that can be used to colorize your 3D model.

Color Conversion

This setting instructs the tool on how to interpret the color information of pixels in your image, thereby influencing the creation of the 3D GLB model. The grayscale option is most commonly used when working with heightmaps, unless you are dealing with specific requirements that necessitate the use of color.

Merge Similar Colors

Use this value to merge similar colors; this is useful if the image is of low quality. A higher number can help reduce the effects of anti-aliasing in the PNG image.

Hole Reduction

With this setting, it is possible to reduce the inclusion of small holes within the 3D model caused by small, darker areas of the source PNG file, which can be useful in situations where the source image has not been optimized for use with the tool.

Transparency Conversion

When your PNG file has a transparent background, this option can instruct the tool on how to treat the transparency, with the transparency converted to either black or white.

Enable Smoothing

When this setting is enabled, the conversion tool will attempt to smooth out any "spikes" within the 3D model that are caused by contrasting pixels in the image being in close proximity to one another.

Z-Axis Mirror

With this option enabled, the tool will mirror the 3D geometry of the generated GLB model along the Z-axis.

Generate Preview

If you would like the tool to create a 3D preview of your model, then please select this option. It is on by default.

File Format Information for PNG to GLB

ExtensionPNG
Full NamePortable Network Graphics
TypeImage
Mime Typeimage/png
FormatBinary
ToolsPNG Converters, Create Cookie Cutter, PNG Viewer
Open WithPaint.NET, Photoshop

Description

The PNG graphics file format is a commonly used format for storing 2D images, which can be highly compressed by the use of 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-1990s 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

The GLB file format, which can also have the GLTF file extension depending on whether the content is binary or text/JSON, is a 3D file format used to describe 3D worlds and, as such, contains geometric data such as vertices, faces, normals, animations, and other 3D scene-related data.

The format, described by its creators as the "JPEG of 3D", has gained in popularity and is supported by a wide range of 3D modeling applications such as Blender and MeshLab. The GLB format is an open standard that is maintained by the Khronos Group.

GLB Notes

If your original model file contains texture images and other texture-related data, these will be included in the final GLB file.

Image to GLB Frequently Asked Questions

What does this tool do?

Our tool converts image (bitmap) data into 3D geometry, which is then saved to the common GLB file format.

What files does it support?

The PNG to GLB tool can convert the most common image file formats, such as PNG, JPG or any one of our supported image formats. The output is provided in GLB format, which can be used in most 3D graphics applications.

How does the tool interpret the image pixel data?

3D geometry is created based on the luminosity of each pixel in the source image. For example, using the default tool settings, a black pixel represents a 3D pixel height of 0mm, and a white pixel represents a 3D pixel height of 10mm. Colors in between these will be converted to a 3D pixel in this range.

What does the "Invert Output" option do?

This option reverses the black-to-white range conversion, so with this option set, a black pixel will be rendered as a 3D pixel of 10mm in height, and a white pixel will be rendered as 0mm.

How do I control the Model detail?

The "Detail" option allows you to control the resolution of the created GLB file. Low detail will generate the model quickly and result in a smaller file. The High option will take longer to generate and can result in very large download files.

What does the "Enable Smoothing" option do?

With this option, the PNG to GLB converter will attempt to remove or smooth out any spikes in the resulting GLB 3D model. Spikes are usually caused by highly contrasting adjacent pixels in the source PNG file.

What is the maximum PNG resolution I can upload?

The PNG you upload can be any size; however, our tool will resize your image to a maximum of 800x800 pixels for normal users, and for premium subscription holders, this is increased to a maximum of 1200x1200 pixels.
