免費線上 PS 轉 DJVU 轉換器

This is an expansion of the PostScript programming language that’s often used in the publishing business. It was developed in 1982 by Adobe Systems. Before the introduction of PS, printing text and images on one page wasn’t possible. PostScript makes this possible by giving a printer commands to print out text and graphical information as needed. PS also contains print coordinates for objects on a page.

DjVu is a computer file format designed primarily to store scanned documents, especially those containing a combination of text, line drawings, indexed color images, and photographs. It uses technologies such as image layer separation of text and background/images, progressive loading, arithmetic coding, and lossy compression for bitonal images.
