Filee Converts Files Offline When You Drop Them on a Donut Menu That Opens at Your Cursor
Hold a modifier key, drag a file, and Filee pops a ring of only the formats that fit it. The MIT-licensed app converts images, PDFs, Office files, e-books, CAD and 3D models locally on Windows, macOS and Linux, and passed 17,000 GitHub stars in its first month.
The donut is the whole interface. Drag a file while holding the key and a ring of targets appears where the pointer is, and “only formats that fit the files appear,” so a photo doesn’t offer you spreadsheet formats. For the rest: “press Tab or turn the mouse wheel while it is open to flip it over to less common formats and tools.” The converted file lands beside the original.
The README’s range is wide: “Images, PDF, Word, Excel, PowerPoint, HWP, e-books, archives, fonts, CAD, 3D models and geospatial data.” HWP, the Hangul Word Processor format, is a rare sight in an English-language converter. The count depends on where you look: the README headline says “270 formats, no other software,” while the repo’s own description says 263. Either way it’s more than most people will ever click.
Two features go past the drag gesture. “Watch folders convert every file that lands in them,” so a folder can convert whatever gets saved into it with no clicks. And “the filee command uses the same engines and presets as the app,” for scripts and batch jobs.
It’s available for Windows 10 and 11, Linux x64 and ARM64 (Ubuntu 22.04 and later), and macOS 13 and later as a preview. Mac users get a warning up front: “The build isn’t notarized yet, so allow the first start in System Settings → Privacy & Security → Open Anyway.” The project is “MIT, © 2026 Myeonggu Kim (KnifeLemon) and Filee contributors,” and the repo, created September 29, had passed 17,000 stars by October 29. The project site at filee.sh has a 27-second video and an interactive demo.
What the README doesn’t spell out is how it gets that many formats into one app with “no other software,” and which engines sit underneath each one.
Converters have always been either powerful or friendly. The command-line tools that do the real work rarely come with an interface anyone would call obvious, and the friendly apps tend to cover a few formats. Filee’s bet is that the drag you were already making is the interface, and the 17,000 stars in a month say people agree. The unnotarized Mac build and the preview label are the signs it’s still early.
