A PBM file, short for Portable Bitmap, is a simple and straightforward image file format used to store monochrome (black and white) images. It's part of the Netpbm family of formats, which includes PGM (Portable Graymap) and PPM (Portable Pixmap). PBM files are incredibly basic, containing only two colors - black and white - represented as binary values, typically 0 for black and 1 for white. Due to their simplicity, PBM files are easy to create, manipulate, and read, making them an excellent choice for tasks where color or complex image structures are not necessary.

PBM files are often used in various applications, including simple graphics, text-to-image conversions, and basic image processing tasks. Their compact size and easy-to-parse structure make them suitable for situations where efficiency and simplicity are crucial. For example, PBM files are commonly used in computer programming to represent and manipulate bitmap images, especially when dealing with fonts, icons, or simple graphical elements in applications.

While PBM files are limited to black and white images, they can be converted into other formats like PNG or JPEG if color or grayscale is required. Additionally, because they are plain text files, PBM images can be edited manually using a text editor or generated and manipulated programmatically with ease, making them a versatile choice for certain image-related tasks.

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.
