GMT to WEBP Conversion: FAQ

What are GMT files?

The GMT format is associated with Generic Mapping Tools, an open software package consisting of tools for handling geographical and Cartesian data, designed for use via command-line. The most recent version of the GMT format was optimized to support more geometry types and attributes. Such files can be used for producing complex PostScript illustrations of detailed maps, with a wide range of applications in geospatial science, as well as biology, physics, medical research etc.

What are WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
