Tip:You can combine VMF Optimizer with traditional file archivers, such as 7Zip, to compress the maps even further.
Important:Saving the file will re-add the default values again, increasing the file size back to it's original size. Thus the tool is best used for archival purposes.
Warning:Custom FGDs may change default values. It is recommended to disable them, or else the map may be corrupted.

VMF Optimizer is an open-source program that reduces the file size of VMF files. The tool was designed with 
Team Fortress 2 in mind, but can work with any Source game.
Features
The program will remove VMF parameters that have default values. When the modified file is opened, Hammer will fill the missing parameters with default values; nothing changes, hence lossless optimization.
Maps made in Hammer and Hammer++ can be compressed to around 90-95% and 60-70% of their original size respectively.
