How HEIC to PNG Conversion Works
Like HEIC-to-JPG, this conversion decodes the HEVC-compressed image from the HEIF container using CoreImage. However, instead of re-encoding with lossy JPEG compression, the full-resolution bitmap is encoded as a lossless PNG. This means zero quality loss — every pixel is preserved exactly. The trade-off is larger file sizes: a 12MP photo might be 5 MB as HEIC, 3 MB as JPG, but 15-25 MB as PNG. EXIF metadata and color profile (Display P3 or sRGB) are preserved.
Common Use Cases
- Extracting photos for use in graphic design where lossless quality is required
- Preserving transparent backgrounds from Live Photo subjects or Portrait mode cutouts
- Creating print-quality images from iPhone photos without any compression artifacts
- Preparing images for scientific or medical documentation where pixel accuracy matters
HEIC vs PNG — Key Differences
| Feature | HEIC | PNG |
|---|---|---|
| Description | HEIC is Apple's high-efficiency image format, offering great compression but limited compatibility outside Apple devices. | PNG is a lossless image format that preserves every pixel perfectly. Unlike JPG, PNG introduces zero compression artifacts, making it ideal when image quality is paramount. |
Tips for Best Results
- PNG files are much larger than JPG — only use PNG when you need lossless quality or transparency
- For photos going on social media, JPG is usually the better choice (smaller files, no visible difference)
- PNG is ideal for screenshots, diagrams, and graphics with text — these compress very efficiently in PNG
