File format information for PFM and PNG

Full NamePortable float map
Mime Typeapplication/octet-stream

A PFM (Portable Float Map) file is a type of raster image file format used to store grayscale or color bitmap images with high precision. Unlike many other image formats, PFM files store pixel values as floating-point numbers, allowing for a wide range of values between 0 and 1 or -1 and 1 for each pixel. This high precision makes PFM files suitable for tasks like high dynamic range (HDR) imaging, where pixel values may need to represent a wide range of luminance or color data. PFM files are commonly used in computer graphics and image processing applications.

PFM files consist of a header section and an image data section. The header contains information about the image, such as its width, height, and whether it is in color or grayscale. The image data is stored as a sequence of floating-point values, with each value representing the intensity or color of a pixel. PFM files are known for their simplicity and ease of use, as they do not use complex compression or encoding schemes. This simplicity makes them a preferred choice for certain types of image manipulation tasks.

One of the key advantages of PFM files is their ability to accurately represent high dynamic range images, which contain a wide range of brightness levels. Because PFM files can store floating-point pixel values, they can faithfully capture the subtle variations in luminance or color that are often present in HDR images. This makes PFM files valuable in industries such as computer graphics, visual effects, and photography, where precise image data is crucial for achieving realistic and visually appealing results.

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.
