From the developer:
OldHex does the following: Batch convert multiple Classic Mac apps or documents into the BinHex (HQX) format. BinHex format protects Classic Mac files when being sent through the Internet (FTP, Email). Informs you if unsupported files are selected (Mac OS X apps, other OS X Bundles). Converted files retain their original name automatically. User selected destination for converted files. Original files remain unmodified. Fast conversion.
You may want to check out more Mac applications, such as pdf-DocPro, Simply Notes or Pads X, which might be similar to OldHex.
