MHTML, short for MIME HTML, is a file format that archives web pages. The format combines HTML code, images, JavaScript, and other resources into a single file using MIME type multipart/related. This method of encapsulating a complete webpage (or set of webpages) in a single file makes MHTML files convenient for saving, sharing, and viewing web content offline. MHTML files typically have the extension .mhtml or .mht and can be opened by various web browsers.
PFS Art Publisher Image (ART) is a raster graphics file format used for storing digital images. It was developed by Progressive Networks for use in their Progressive FreeStyle Art Publisher software. ART files are compressed using the run-length encoding (RLE) algorithm, which allows them to store large images in a relatively small file size. The ART format supports up to 24-bit color and is often used for storing digital photos and other images.
