Convert JFIF to SIX

The JPEG File Interchange Format (JFIF), developed by the Joint Photographic Experts Group, is a standardized method of storing and transferring JPEG-compressed images. Introduced in 1991, JFIF ensures compatibility and interoperability among different platforms and applications. It is extensively used in digital imaging and multimedia for efficient image compression, which reduces file size without significant loss of quality. As a widely adopted format, JFIF supports a range of devices and software, making it a cornerstone in computer graphics and online image sharing.

The SIX file extension, short for "six pixels", is a bitmap graphics format developed by Digital Equipment Corporation (DEC) for their terminals and printers. Introduced initially to send bitmap graphics to DEC dot matrix printers like the LA50, SIX later facilitated the transfer of soft fonts to terminals such as the VT220. This format encodes images using a series of six-pixel-high patterns, making it efficient for transmitting graphics over 7-bit serial links. Rediscovered around 2010, SIX remains in use with modern terminal emulators for tasks like video playback.
