A free, open-source file converter for Windows that you use by dragging.
Hold a key (Ctrl by default), drag files and drop them on a format in the donut that opens right at your cursor.
Website · Download · Get started · Docs
| Right at your cursor No app window to open. The formats appear where you already are, only the ones that make sense for the files you drag. |
170+ formats, no other software Images, PDF, Word, Excel, PowerPoint, HWP, e-books, archives, fonts and CAD work without Office, Hancom Office or LibreOffice. |
Stays on your PC Nothing is uploaded. Filee works offline and saves the result right next to the original. |

- Donut toolbar at the cursor. Hold a modifier key (Ctrl by default) and drag files. Everything is configurable: any modifier combination, mouse button, drag distance, a hold gesture or a keyboard shortcut for the selected files.
- One toolbar per file type. Images, PDF, documents, spreadsheets, presentations, HWP, text, e-books, video, audio, vector graphics, archives, CAD and fonts, plus toolbars for mixed selections. Arrange presets on a live donut by drag & drop, add extensions as tags, right-click or ✎ to edit a preset.
- Presets. Quality, resizing, DPI, metadata, PDF merge and split, page ranges, video quality and resolution, audio bitrate, archive compression, output folder, file name pattern and conflict handling.
- Batch conversion. 1 file or 100, converted in parallel; one failure never stops the rest. "One ZIP" packs any files into a single archive, "Merge PDF" makes one PDF.
- Planned routes. Multi-step conversions are found automatically (e.g. HWP → HWPX → DOCX, EPUB → HWPX → PDF → PNG), each step with the engine that does it best.
- Four ways in. The drag gesture, Explorer's right-click menu (on Windows 11 also in the main menu) and Send To, a keyboard shortcut on the Explorer selection, and the drop zone in the main window.
- Engines you can see. Settings → Engines lists every engine with its version and what it converts; optional engines download with speed and time left.
- Soft, animated UI. Light, dark or system theme, your accent colour, adjustable roundness and a Reduce animations switch for older PCs.
- English, 한국어, 简体中文, following your Windows language by default.

Everything without a mark works out of the box: no Microsoft Office, Hancom Office or LibreOffice needed, and Filee never uses programs installed on your PC. Optional engines Filee offers to download: ¹ Ghostscript, ² LibreOffice, ³ Pandoc, ⁴ calibre, ⁵ FFmpeg. Details, including what each engine keeps and leaves out: docs/ENGINES.md.

Install: download the latest Filee-<version>-win-Setup.exe from
Releases (Windows 10/11, 64-bit).
- Everything common is in the installer. Images, PDF, Word, Excel, PowerPoint, HWP, e-books, archives, fonts and CAD work right away.
- Large engines are optional. On first start Filee offers the engines for video and audio (FFmpeg, ~100 MB) and for rare formats (LibreOffice, calibre, Ghostscript, Pandoc), each with its size. Install or remove them any time in Settings → Engines, which shows download speed and time left.
- You hear about updates. When a new release is out, Filee says so at the bottom of the menu, in a notice and in the tray menu, and opens the latest release to download it. Run the new installer; your settings are kept.
macOS support is planned.
