QCT QuickChart Memory-Map Decoder


QCT (QuickChart) is the file format used by Memory-Map software to store digital maps and charts.

The following software has been developed using a document by Craig Shelley which describes the file format and which was produced without decompiling the Memory-Map software itself.

The software simply provides the ability to read a file format. However like all tools it must be used responsibly; in particular it must not be used for circumventing copyright.


This program converts a QCT file into a PNG image.

usage: qct2png [-d] [-v] [-q] -i map.qct [-o map.ppm]

-v      verbose
-q      query metadata only, no image extracted
