HEIC (iPhone default) is unsupported on Windows, Linux, most browsers, and many web forms. Use this converter whenever you're sharing iPhone photos outside Apple's ecosystem. For JPG → PNG or PNG → JPG, native OS tools (macOS Preview, Windows Photos) work fine for single files. The converter is faster for batch processing. Alternative: CloudConvert handles more exotic formats (RAW camera files, SVG) but requires uploading to their servers.
A typical iPhone 14 photo: 4.1 MB HEIC at 4032×3024 → 2.8 MB JPG (91% quality) or 1.6 MB WebP (80% quality), both visually identical to the original at normal viewing distance.
