// ABOUT ICO
ICO is the standard Windows icon container format used for favicons and application icons. A single ICO file can embed multiple resolutions (16x16, 32x32, 48x48, 256x256) so the operating system or browser can select the most appropriate size. ICO is the required format for the classic favicon.ico file that browsers request from every website.
// ABOUT PNG
PNG uses lossless compression with full alpha-channel transparency support. It preserves every pixel exactly, making it the standard choice for screenshots, logos, web graphics, and any image where precision matters. PNG files tend to be larger than lossy alternatives but guarantee no quality degradation.

Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device.
