Convert any file by dragging it — no office software needed

Filee is a free app that converts files right where you are: hold a key, drag a file, drop it onto a format — done.

01KnifeLemon/Filee 20kC#

It's a drag-and-drop converter: hold Ctrl (or Option on Mac), drag a file and drop it on the format you want — conversion starts on its own.

When it helps

Useful if you often need to change file formats — images, documents, PDF, video — and don't want bulky office suites or shady online converters. Skip it if you rarely convert files or aren't on Windows/macOS/Linux.

Pros

  • Handles 270 formats without installing office suites
  • Works fully offline — nothing gets uploaded
  • Has a command-line version, handy for agent automation
  • Converts many files at once and can auto-convert watched folders

Cons

  • macOS build isn't notarized — you must allow it manually
  • Drag-and-drop doesn't work on Linux Wayland, only the drop zone or menu

How to set it up — step by step

  1. 1Open https://github.com/KnifeLemon/Filee/releases/latest and download the build for your system.
  2. 2Install it following the README instructions for your OS (Windows, macOS, or Linux).
  3. 3Open your AI agent (Claude Code, Codex) in the folder with your files.
  4. 4Send the agent the text from the block below.
  5. 5Check that the agent shows you the converted result, then open the files.

Text for your agent

Copy this and send it to your agent — Claude Code, Codex, any of them:

Install Filee from https://github.com/KnifeLemon/Filee/releases/latest — pick the build for your system per the README, and ask it to run a folder of files through the converter using the `filee` command. Show me the result.

Runs on a regular laptop — fully offline, no GPU needed; the macOS build isn't notarized yet, so the first run needs manual approval.
