HEIC

High Efficiency Image Format

HEIC (High Efficiency Image Format) is a modern image file format introduced by Apple, based on the HEIF (High Efficiency Image File) standard and utilizing HEVC (High Efficiency Video Compression) for improved image compression. HEIC files offer higher image quality at smaller file sizes compared to JPEG, and they support features like live photos, 16-bit color depth, and transparency. However, HEIC is not as universally supported across different platforms and software as more established formats like JPEG or PNG, potentially requiring conversion for broader compatibility.

ICO

Microsoft icon

ICO is a file format used to store icons on Microsoft Windows. It supports images of various sizes and color depths, and it can contain multiple images within a single file, allowing icons to be displayed in different resolutions and color depths depending on the user’s settings. While ICO files are essential for creating application and file icons in Windows, they are less commonly used for other purposes due to their specific functionality and limited support on non-Windows platforms.
