Convert files locally with a drop zone, circular menu and command line.
Filee is a free, open-source file converter for Windows, Linux and a preview version for macOS. It brings several conversion routes into one application, with a circular toolbar, a Home drop zone, presets, batch processing and a command-line tool. Its practical appeal is keeping routine conversions on the computer rather than handing each file to a different website.
The app can work with images, documents, PDFs, archives, structured data and other categories. Some routes use optional engines such as LibreOffice, FFmpeg, Pandoc, calibre or Ghostscript. A long supported-format list should not be read as a promise that every format converts into every other one. Check the actual input/output route and its engine requirements.
Filee's privacy policy says file conversion is local, with no file uploads or telemetry. Update checks and downloads for optional engines or language data still use the internet. Downloading a file from a browser link is also different from converting an existing local file. Local processing is not a guarantee that an unfamiliar document is harmless.
In our limited Linux check of version 2.4.0, the command line successfully converted a synthetic PNG to WebP, JSON to YAML and a short Markdown note to PDF. We inspected the outputs and kept the originals. The test did not cover complex Office layouts, video, watch-folder reliability or global desktop drag gestures, and the machine already had several optional tools available.
Version 2.4.0 is the patched release named in two published security advisories affecting versions through 2.3.0. Download a current official release rather than an older copy. The advisories discuss update verification, handling of documents and other safeguards; they do not establish exploitation against users.

Read our Filee discovery and three-file Linux trial for the results and test limits.
Choose a supported output around the cursor or use the Home drop zone. Global drag behaviour depends on the desktop session.
Reuse supported quality, naming and output-folder settings across files.
Convert files and folders, inspect available formats and receive per-file JSON results for scripting.
Add engines for specific routes and configure conversions for files entering selected folders. Check outputs before relying on unattended jobs.
No. The policy describes local conversions without uploads or telemetry, but update checks and requested downloads use the network. Automatic update checks can be disabled in Settings.
Use the current official release. At this check, 2.4.0 was the latest and was marked patched in both security advisories; versions through 2.3.0 were marked affected.
Do not assume that. The README requires X11 for global drag gestures and points Wayland users to the drop zone and file-manager menu. Check current desktop-specific guidance.
