Compare WebP Image and High Efficiency Image formats — understand the key differences and when to use each
WebP Image
WebP is a modern image format developed by Google in 2010, designed to provide superior compression for web images. WebP supports both lossy compression (like JPG but 25-35% smaller) and lossless compression (like PNG but 26% smaller), along with transparency and animation in a single format. The lossy mode uses VP8 video codec technology for efficient compression, while lossless mode uses a predictive algorithm. WebP also supports animated images as a modern alternative to GIF with much smaller file sizes and better color support. All major browsers (Chrome, Firefox, Safari, Edge) and platforms now support WebP. It's the recommended image format for web performance optimization, significantly reducing page load times and bandwidth usage. WebP supports ICC color profiles, EXIF and XMP metadata, and alpha channel transparency. Many content delivery networks and image optimization services automatically convert images to WebP.
High Efficiency Image
HEIC (High Efficiency Image Container) uses the HEVC (H.265) video codec for image compression, providing approximately 50% better compression than JPEG at equivalent quality. Apple adopted HEIC as the default photo format for iOS 11+ and macOS High Sierra+ devices. A single HEIC file can contain multiple images (like burst photos or Live Photos), depth maps, alpha channels, and HDR content. HEIC supports 16-bit color depth and wide color gamut (P3), resulting in more vibrant and detailed photos than JPEG. However, HEIC has limited compatibility outside the Apple ecosystem — many Windows applications, web browsers, and social media platforms require JPEG or PNG. Converting HEIC to JPG or PNG ensures universal compatibility while preserving image quality.
