PNG uses lossless compression and is right for graphics, screenshots, logos, and images containing text. It also helps transparent backgrounds.
WEBP is a modern image format designed for the web. It may provide excellent image quality while producing smaller files than traditional JPG or PNG formats.
HEIC is commonly utilized by Apple units and might store high-quality photos with comparatively small file sizes. Nonetheless, it may should be transformed to JPG or PNG for compatibility with certain programs and websites.
