The LibTIFF software provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. The latest version of the TIFF specification is TIFF File Format Specification.

Included in this software distribution are:

- a library, `libtiff`, for reading and writing TIFF images

- a small collection of tools for performing simple manipulations of TIFF images

- documentation for the library and tools.

The `libtiff` library, along with associated tool programs, should handle most of your needs for reading and writing TIFF images.

LibTIFF is portable software, supported on various operating systems including UNIX (Linux, BSD, MacOS X) and Windows.

Warning

libtiff v4.5.1 will be the last one supporting most TIFF tools (except tiffinfo, tiffdump, tiffcp and tiffset), whose maintenance will be discontinued, due to the lack of contributors able to address reported security issues. Starting with libtiff v4.6.0, their source code, at this time ,will still be available in the source distribution, but they will no longer be built by default, and issues related to them will no longer be accepted in the libtiff bug tracker.
