What Filee does for PNG → ICO
One ICO covers everything Windows needs for desktop, Explorer and taskbar icons, and it works as a website favicon too. Start from a square PNG of at least 256×256 px for the sharpest result.
- Built in: works right after installing Filee, with nothing else to download.
- Engine: ImageMagick.
- ICO files hold 256, 128, 64, 48, 32 and 16 px by default; the sizes can be changed in the preset.
- 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.
About PNG and ICO
ICO
Windows icon
ICO is the Windows icon format. One ICO file holds the same picture at several sizes (for example 16, 32, 48 and 256 pixels), so it looks sharp everywhere from the taskbar to website favicons.
