标签图像文档格式（Tagged Image File Format，简写为TIFF）是一种灵活的位图格式，主要用来存储包括照片和艺术图在内的图像。它最初由Aldus公司与微软公司一起为PostScript打印开发。TIFF与JPEG和PNG一起成为流行的高位彩色图像格式。TIFF格式在业界得到了广泛的支持，如Adobe公司的Photoshop、The GIMP Team的GIMP、Ulead PhotoImpact和Paint Shop Pro等图像处理应用、QuarkXPress和Adobe InDesign这样的桌面印刷和页面排版应用，扫描、传真、文本处理、光学字符识别和其它一些应用等都支持这种格式。如今Adobe公司从Aldus获得了印刷应用进程-PageMaker之后控制着TIFF的规范。

TIFF is a computer file format for storing raster graphics images, popular among graphic artists, the publishing industry, and photographers. The TIFF format is widely supported by image-manipulation applications, by publishing and page layout applications, and by scanning, faxing, word processing, optical character recognition and other applications.
