Free Online PTX to PNG Converter

Here is our free-to-use PTX to PNG conversion tool that will take your 3D PTX model file and convert it into a high-quality PNG image file. If you wish to batch convert multiple PTX files, our converter supports up to 20 files at a time, with a dedicated download link being provided for each image file once completed.

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 PTX file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted PTX file before this time.

With our 3D model PTX to PNG converter, your PTX file is uploaded, and a snapshot of the rendered model is created and saved into a PNG image file format. If your PTX model has any textures, you can include them with your PTX file at the time of upload. Our tool will automatically determine if any additional files are required to render your PTX 3D model.

A PTX file is a 3D point cloud file format. Containing only vertex positional information about the 3D object allows the format to remain simple and easy to implement in 3D modelling applications where only positional data is required.

Inside a PTX file is plain ASCII content containing each vertex position on a single line of the text document. It is also possible to specify a colour for the point, allowing for full-colour point clouds to be stored and rendered.

Support for opening and displaying PTX files is limited; however, there are various specialist 3D applications that work with point clouds that can be used to open PTX files.

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.

Information for converting from PTX to PNG

Our tool will internally render your PTX file and capture an image of the 3D render, which will be saved to a PNG file using a high-quality setting, ready for you to download.
