Gzip utils is a set of utility scripts to work with gzip, tar and, to a lesser extent, zip files.

You can use Gzip utils to extract the contents of .gz and .tar files, and read the metadata of .gz, .tar and .zip files, listing for example the files contained in an archive with their attributes without actually expanding it.

Moreover, this a GML only asset, you don't need any external extension to use it. This means out of the box compatibility with almost every export module that supports buffer operations (with the exception of HTML5 and Javascript based exports).

This is not a compression utility. All the provided functionalities deal with reading and extracting/decompressing archives.


  • Read the contents and metadata of gzip, tar and zip files without extracting
  • Decompress / Extract gzip and tar files
  • No external dll or library required
  • Support for GM:S1 and GM:S2
