Convert PNG to HEIC — Massive Size Reduction
PNG files are often very large because of their lossless compression. Converting to HEIC typically reduces file size by 80-95% for photographic content while maintaining excellent visual quality. Unlike JPG, HEIC preserves transparency from the original PNG, making it a compelling alternative for the Apple ecosystem.
