BMP files are used to store bitmap images in a simple and uncompressed manner. Introduced by Microsoft in the 1980s as a standard image format for use with their Windows operating system, the format has evolved over the years and is still relevant today.

Due to the uncompressed nature of BMP files, they can quickly grow in size when using high resolutions. Modern formats such as PNG and JPEG can be used as an alternative when dealing with larger images or images where transparency is a requirement (PNG only).

The BMP format supports different pixel color depths, allowing creators to minimise file sizes if their content has a lower color depth. Due to their age and popularity, BMP files can be opened in most modern image editing applications without requiring conversion tools.

Extension	PNG
Full Name	Portable Network Graphics
Type	Image
Mime Type	image/png
Format	Binary
Opens With	Paint.Net, Photoshop

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