Convert PNG files to ICNS on Windows 10 and 11: free, offline and in batches. Drag the files onto ICNS in Filee's format donut and the ICNS files appear next to the originals.

How to convert PNG to ICNS on Windows

  1. 1

    Select your PNG files

    In File Explorer or on the desktop, select one PNG file or as many as you like.

  2. 2

    Hold Ctrl and drag

    Hold Ctrl (or the key you set in Filee) and drag the files. A donut of formats opens at the cursor. Prefer menus? Right-click and choose Convert with Filee.

  3. 3

    Drop on ICNS

    Release the files over ICNS. A progress ring counts up, and each ICNS file is saved next to its original.

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.

PNG can also become

  • JPG
  • WEBP
  • AVIF
  • TIFF
  • BMP
  • GIF
  • ICO
  • PSD
  • TGA
  • PPM
  • JPEG XL
  • JPEG 2000
  • PDF
