Converts 266 formats, including images, PDFs, documents, videos, audio, and archives. It handles major document formats such as HWP, DOCX, and XLSX even if Office, Hancom Office, or LibreOffice are not installed. All operations are performed locally, and files are not uploaded to external servers.

Processes multiple files in parallel and automatically finds conversion paths that require multiple steps, such as converting from HWP to DOCX. It also provides a feature to monitor a specific folder and automatically convert newly added files. Conversion results are saved next to the original files.

Supports Windows, macOS, and Linux, and is distributed under the MIT license. It is suitable for environments where installing office software is difficult or for developers who want to avoid cloud uploads. It can be run as a portable application without a complex installation process or installed using its own installer.
