2.5 Official Scratch to EXE converter
On Scratch, an important goal is to have anyone be able to look at the code for any project. This philosophy is not only important for learning code and remixing, but is also important for moderation purposes; for more information, see #3.2 and #4.1 on this list. Converting to EXE (or any other black box executables) will prevent users from looking at the code, and hence goes against this philosophy. Third party converters do exist, and you are allowed to use those, but the Scratch Team will not make an official converter.
