ModLatch is a Keen 1–3 tileset graphics importing/exporting utility written by Andrew Durdin. It was written for the DOS platform, using the DOS 32-bit Protected Mode programming Interface (DPMI), and released under an unspecified license.

The initial version 1.0 used the Allegro API for bitmap input/output routines, but the next version, 1.1, included built-in bitmap I/O support, thus not depending on a external library. The tool became obsolete when its author improved it, added support for variable-size sprites importing/exporting, and released the result as a new utility, ModKeen, under the terms of the GNU General Public License (GPL).
