Free Online PNG to OBJ Converter

Welcome to our PNG to OBJ image to 3D model file converter that will take your PNG image file and convert it into a full 3D model that you can then download in the OBJ format using either a heightmap or extrusion process. Our tool supports up to 20, PNG to OBJ conversions at one time, allowing you to batch convert your files quickly.

Drag and drop your files here to upload or click the button above.
A maximum of 20 files can be converted at once.

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

Our PNG to OBJ converter offers several options when converting your PNG image files; these options are accessed by clicking the button next to your file once selected. Some of the options available include the choice of mode, which can be either heightmap or extrude (with color as an additional option), the dimensions, smoothing options, and more.

A PNG file is a two-dimensional image file format often used to store high-quality logos, icons, and other imagery. PNG files first emerged in the early 1990s as an alternative to the GIF format, which was in widespread use at the time. PNG files have garnered support over the years to at least equal or surpass that of the GIF format. You will find all modern image editing or viewing applications will support PNG files.

Part of the success of the PNG format is its use of special compression techniques that allow a high-resolution image to be compressed into a very small file size. The compression used in the PNG format is lossless compression, ensuring no image detail is lost when an image is saved to the PNG format.

Uses

The PNG format is ideally suited for storing images that require no loss of detail or have transparent areas, such as company logos and computer graphics icons. It is not suited for storing general photos as, due to the nature of the compression, it will result in very large file sizes. Other formats, such as JPEG, use a lossy compression method, and this format is better suited to full-color photographic images.

An OBJ file is a text-based file format used for the storage of 3D model data. The format was developed in the 1980s by Wavefront Technologies as a means to store the geometric mesh data associated with a 3D model. It has garnered widespread support in the following years, and you will find options to load from and save to the OBJ format in most modern 3D modeling applications.

As OBJ files are essentially text files, they can grow quite large when working with large and detailed 3D models.

Mesh Geometry

Within a 3D OBJ file are lists of vertices, mesh faces, face normals, texture coordinates, and more. The vertices, normals, and texture coordinates are stored in a continuous list and are indexed referenced within a separate list of mesh faces, ensuring optimal use of space within the file. A mesh face may contain three or more points, each of which can use a unique vector normal and texture coordinate.

Frequently Asked Questions

How do I convert my PNG to OBJ?

First, click the "Select File" button and choose your PNG file. We will upload and convert your PNG file. Once the conversion from PNG to OBJ completes, use the provided link to download your OBJ file.

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

We aim to process all PNG to OBJ file conversions as soon as possible; this should take around 5 seconds; however, this may be longer for larger files.

How is my PNG image turned into a 3D model?

Our tool uses a heightmap process in which the OBJ model is created based on the color and brightness of the individual pixels in your PNG image.

Is there a size limit for uploaded image files?

Yes, our conversion tool has a limit of 600x600 pixels for the PNG image and will resize any file that is larger than this.
