Adobe Inc. ( ə-DOH-bee), originally called Adobe Systems Incorporated, is an American multinational computer software company. Incorporated in Delaware and headquartered in San Jose, California, it has historically specialized in software for the creation and publication of a wide range of content, including graphics, photography, illustration, animation, multimedia/video, motion pictures and print. Adobe has millions of users worldwide. Its flagship products include Adobe Photoshop image editing software; Adobe Illustrator vector-based illustration software; Adobe Acrobat Reader and the Portable Document Format (PDF); and a host of tools primarily for audio-visual content creation, editing and publishing. Adobe offered a bundled solution of its products named Adobe Creative Suite, which evolved into a subscription software as a service (SaaS) offering named Adobe Creative Cloud.

Adobe was founded in December 1982 by John Warnock and Charles Geschke, who established the company after leaving Xerox PARC to develop and sell the PostScript page description language. In 1985, Apple Computer licensed PostScript for use in its LaserWriter printers, which helped spark the desktop publishing revolution. Adobe later developed animation and multimedia through its acquisition of Macromedia, from which it acquired Adobe Flash; video editing and compositing software with Adobe Premiere; low-code web development with Adobe Muse; and a suite of software for digital marketing management.

As of 2019, Adobe has more than 21,000 employees worldwide, about 40% of whom work in San Jose. Adobe also has major development operations in the United States in Newton, New York City, Minneapolis, Lehi, Seattle, Austin and San Francisco. It also has major development operations in Noida and Bangalore in India.
