// ABOUT HEIC
HEIC (High Efficiency Image Container) is Apple's default camera format on iPhone and iPad since iOS 11. It uses the HEVC video codec to achieve roughly 50% better compression than JPEG at equivalent quality. HEIC supports transparency, depth maps, and burst sequences. However, HEIC encoding requires a commercial HEVC licence, so this tool supports HEIC as an input-only format.
// 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.

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