no_vtf is an open source alternative to VTF2TGA. Unlike its first-party counterpart, it also supports converting VTFs to PNG, TIFF, and EXR, and can also decompress compressed HDR skybox textures.

Tip:Compressed HDR textures are automatically detected by the presence of the string "hdr" near the end of the filename.

Usage: no_vtf [OPTIONS] [--] PATH...

  Convert Valve Texture Format files into standard image files.
  PATH can be either a file or a directory (in which case it is recursively   searched for .vtf files; symbolic links are not followed). Multiple paths   may be provided.
  As the output path, it is possible to specify either a file or a directory.
  Specifying the output file is useful mostly for single-file conversions,   with filters to ensure the output file will be written only once.
  If the output directory is not specified, images are output into the source   directories (in-place conversion). Otherwise, the directory tree for any   found files will be reconstructed in the chosen directory.
  Output LDR/HDR format is selected by its common file name extension. It is   recommended selecting one of the specifically supported image formats (PNG,   APNG, TGA, TIFF, EXR). Other image formats have not been validated to work,   but can still be selected. A secondary format specifically used to output   animated image files can be selected after '|' (see default LDR format as an   example). The "skip" format can be used to skip the R/W step entirely.
  For the specifically supported image formats, compression is configurable   when saving the image. Lossless compression is enabled by default. Lossy   compression is not used.
  The BGRA8888 format can store both LDR and compressed HDR images. The   specific type is either auto-detected by looking at the input file name   (roughly, if it contains "hdr" near the end), or can be set manually.
  It is possible to filter images to convert by min/max resolution (width &   height), and by frames/faces/slices. The former supports exact or closest   match. The latter supports selection by single index or via Python slicing:   https://python-reference.readthedocs.io/en/latest/docs/brackets/slicing.html   It is also possible to specify multiple indices/slices separated by commas.
  Face index mapping: right (0), left, back, front, up, down, sphere map (6).
  After applying filters, only the highest-resolution mipmap is converted by   default. Alternatively, all mipmaps of the high-resolution image can be   converted.
  Animated textures are converted into an animated multi-frame image file by   default. Alternatively, they can also be converted into single-frame images   when animation is disabled.
  The RGB/L and A channels are packed into one file by default. When output   separately, resulting file names will be suffixed with "_rgb", "_l", or   "_a".
  By default, image files are only written if they do not exist already.   Alternatively, they can be overwritten, or writing can be disabled entirely.
  Images can also be read back to verify they have been written properly.   Readback will error if would-be-written data does not match what is in the   file.
  Workers are spawned for each logical core to run the conversion in parallel.   The number of workers can be overridden. If set to 1, conversion is   sequential. Sequential conversion enables more verbose errors to be printed.
  Exit status: Zero if all went successfully, non-zero if there was an error.   Upon a recoverable error, conversion will proceed with the next file.
