KnifeLemon/Filee

Features

• A donut at the cursor: hold a key, drag files and drop them on a format.
• Only formats that fit the files appear.
• Straight from the browser: drag a picture, a link to a file or a download out of Chrome, Edge, Firefox or Safari the same way.
• Filee saves it to your Downloads folder (or keeps only the converted file) and converts it.
• Links are downloaded without your browser's sign-in.
• One toolbar per file type, arranged by drag and drop, with presets for:
• quality, size, DPI
• PDF pages and compression
• video and audio
• output folder and file names
• Two sides to every donut: press Tab or turn the mouse wheel while it is open to flip it over to less common formats and tools.
• Crop before converting: the Crop slice opens pictures one by one.
• Drag the frame, pick a ratio, and only that part is saved.
• Many files at once, in parallel.

Install

Filee shows new releases in its menu and updates itself, keeping your settings and engines. After an update, a few slides show what's new.

Windows: Filee doesn't start (no window, no error)? This happens on Windows 10 that hasn't been updated for a long time, on a PC whose processor supports Hardware-enforced Stack Protection (CET). Windows turns that protection on but lacks a part that .NET needs, so Filee and Setup stop right away.

Do the same with Setup's file name (e.g. Filee--win-Setup.exe), or use the portable ZIP, which needs only these two lines. To undo it, remove the entries in Windows Security → App & browser control → Exploit protection settings → Program settings.

• Windows 10/11: run Filee--win-Setup.exe, or unzip the win-Portable.zip and run Filee.exe.
• Setup is Filee's own installer, in Filee's languages, and needs nothing else on the PC.
• It can add the Explorer menu, start at sign-in, the filee command and optional engines.
• Silent installs take Inno Setup's switches (/VERYSILENT /SUPPRESSMSGBOXES).
• macOS 13+ (preview): unpack the osx-arm64 or osx-x64 package and run ./install.sh.
• Or open the .dmg and drag Filee to Applications (the filee command comes with install.sh).
• The build isn't notarized yet, so allow the first start in System Settings → Privacy & Security → Open Anyway.
• Drag gestures need X11.
• On Wayland, use the drop zone and the file manager's right-click menu.
• Recommended: install the available Windows updates (the latest cumulative update).
• If updating isn't possible: turning the protection off for Filee alone usually works.
• Run this in PowerShell as administrator:

Set-ProcessMitigation -Name Filee.exe -Disable UserShadowStack
Set-ProcessMitigation -Name filee-cli.exe -Disable UserShadowStack

Code signing policy

Filee is developed and published by Myeonggu Kim (KnifeLemon).

• Windows releases are signed with a Certum open source code signing certificate issued to Myeonggu Kim ("Open Source Developer MYEONGGU KIM").
• Releases before it, up to 2.0.0, are not signed.
• SmartScreen can still warn about a new release until it has been downloaded enough ("More info" → "Run anyway").
• macOS packages are ad-hoc signed and not notarized.
• Only files built by this repository's GitHub Actions release workflow are signed, and every release is signed and approved by hand.
• Libraries and programs their makers signed (.NET, SkiaSharp, ImageMagick, the Microsoft C++ runtime …) keep their own signatures; bundled ones that come unsigned (rhwp, 7-Zip and most libraries) are s

概述

A free, open-source file converter you use by dragging. Hold a key (Ctrl, Option on macOS), drag files and drop them on a format in the donut that opens at your cursor.

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. 255 formats, no other software Images, PDF, Word, Excel, PowerPoint, HWP, e-books, archives, fonts, CAD, 3D models and geospatial data work without Office, Hancom Office or LibreOffice. Stays on your computer Nothing is uploaded. Filee works offline and saves the result next to the original.
