The JTF file format, associated with Hayes JT Fax, represents a type of image file specifically designed for fax documents. It is used to store scanned or digitally created documents that are meant to be sent or received through a fax service. The format is optimized for the efficient encoding of black and white images, typical of fax transmissions, ensuring that text and simple graphics are clear and legible. JTF files support a form of compression to reduce file size without significantly compromising the quality of the document, making it suitable for quick transmission over phone lines.
