Convert CRYPT9 to HTML

In case you stumble upon a file with a .crypt9 extension, it's likely that the file has been encrypted by an older version of WhatsApp Messenger and contains chat history. This method is commonly used by individuals to view message history on the latest version of WhatsApp. However, to convert the file to HTML, you must first decrypt or decode it, assuming that it contains HTML content. Regrettably, there is currently no easy and direct way to convert or decrypt .crypt9 files into HTML web pages.

Due to the fact that .crypt9 files were only used for a very short period of time and were soon replaced by higher versions of WhatsApp database backup encrypted files, this conversion from .crypt9 to html is rather rare and more or less obsolete.

Simply put, it is impossible to convert CRYPT9 to HTML directly.
Thus, there is no so-called crypt9 to html converter or a free online .crypt9 to .html converter to be found.
