What is it?
Filee is a desktop file converter for Windows, with macOS and Linux in preview. You hold a modifier key, drag files, and drop them on a format in a donut menu that opens at the cursor. Only the formats that fit the dragged files are shown.
Conversion runs locally and nothing is uploaded. Images, PDF, Word, Excel, PowerPoint, HWP/HWPX, e-books, archives, fonts, CAD and 3D models work without Office, Hancom Office or LibreOffice. Some formats such as video, audio, or certain document routes use optional engines such as FFmpeg, Pandoc, LibreOffice, calibre or Ghostscript, downloaded only when you choose to install them.
Beyond drag and drop, Filee offers batch conversion with parallel processing, multi-step routes like HWP to HWPX to DOCX, watch folders, a right-click menu, and a `filee` command-line tool that shares the same presets.
