Compare High Efficiency Image and Adobe Photoshop Document formats — understand the key differences and when to use each
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.
Adobe Photoshop Document
PSD (Photoshop Document) is Adobe Photoshop's native file format. PSD preserves layers, masks, blend modes, adjustment layers, smart objects, text layers, paths, and all editing capabilities. It supports RGB, CMYK, LAB, and other color modes at up to 32-bit depth. PSD is the standard working format for graphic designers, photographers, and digital artists. For sharing, PSD files should be converted to PNG, JPG, or PDF.
