For favicons, use 16x16 or 32x32 pixels. For Windows desktop icons, 48x48 or 256x256 pixels work best. The converter preserves PNG transparency, so your icons look clean on any background.
Customize your PNG before converting to ICO. The converter offers six color filter options: grayscale, monochrome, negate, retro, and sepia. Apply a filter to match your icon to a specific design style without opening a separate image editor.
Set the DPI (dots per inch) value between 10 and 1,200 to control how the icon renders on high-resolution displays. Higher DPI values produce sharper icons on Retina and 4K screens.
