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 minimising 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 colors down to 256 or 16 colors to help reduce the file size of the PNG.

A PLY file, short for Polygon File Format or Stanford Triangle Format, is a popular file format used to represent 3D geometric models, particularly those consisting of polygonal meshes. Developed at Stanford University, PLY files are widely used in computer graphics, 3D printing, and various other applications where 3D data representation is essential. The format is designed to be simple and flexible, making it easy to read, write, and process by both humans and computer programs.

A PLY file typically consists of a header section followed by the data section. The header contains information about the file, such as the data format (binary or ASCII), the number of vertices and faces, and the properties of each element (e.g., position, color, normal). The data section contains the actual vertex and face data, where vertices are represented by their coordinates and optional properties, while faces are defined by indices that reference the vertices, forming the polygons that make up the 3D model.

Due to its simplicity and extensibility, PLY has become a widely adopted format for storing 3D data. Its ASCII representation allows for easy inspection and manual editing, while the binary format provides more compact storage, making it ideal for large datasets. Whether you are working on 3D modeling, simulations, or scientific visualization, understanding the PLY file format can be invaluable in effectively manipulating and exchanging 3D data.

Information for converting from PNG to PLY

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

Frequently Asked Questions

How can I convert my PNG file to PLY?

First click the "Upload..." button, select your PNG file to upload. Your PNG file will be uploaded to our servers. When the PNG to PLY conversion has completed, you can download your PLY file straight away.

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

We aim to process all PNG to PLY 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 conversion to the PLY 3D Point Cloud format?

Our PNG conversion tool will extract only the vertex data from your PNG file. This will then be used to create the final PLY file.

How is the 3D model generated from my PNG image?

Our tool uses a Heightmap process whereby the PLY 3D model is created based on the luminosity of the individual pixels in you 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.
