What Filee does for PNG → ICNS
Making a Mac app icon on Windows usually needs extra tools; Filee turns a PNG into an ICNS file directly. Use a square 1024×1024 px PNG so the Retina sizes stay sharp.
- Built in: works right after installing Filee, with nothing else to download.
- Engine: ImageMagick.
- Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
- Private: files are converted on your PC and never uploaded, even without internet.
- Saved next to the original, or in a folder and with a file name pattern you choose.
