To convert other file formats to the "HTML Application" file type, you need software like Microsoft Windows or a similar tool.
About HTA files
An .HTA (HTML Application) is a legacy executable file designed for Microsoft Windows. Introduced in 1999, it relies on the outdated Internet Explorer engine (Trident) to render HTML, CSS, and scripts (VBScript or JScript) as a standalone desktop application via mshta.exe. You can read more about this architecture on Wikipedia's HTML Application page. The primary disadvantage of an .HTA file is its severe security risk. Unlike standard web pages, .HTA files run completely outside the web browser sandbox. They have unrestricted access to the local file system, command prompt, and Windows Registry. Because of this, modern systems flag them as dangerous, and they are frequently weaponized as delivery mechanisms for malware and ransomware. Furthermore, they are proprietary, completely incompatible with macOS or Linux, and rely on an obsolete rendering engine. To handle these files safely, you must extract their code rather than execute them. For web use and safe viewing, convert .HTA to HTML or TXT to inspect the underlying source code without triggering the dangerous scripts. For archival purposes, save the code as PDF to maintain a non-executable record. Drag and drop your file to analyze and convert it - free, online, and without installing software, ensuring you can read the code without risking your computer's security.
