Conversion Algorithm Details
HEIC files use the High Efficiency Video Codec (HEVC/H.265) compression standard for still images. The conversion process extracts the compressed image data, decodes it using HEVC algorithms, and re-encodes it into PNG format using the Portable Network Graphics lossless compression standard.
Compression Efficiency = (Original Size - Converted Size) / Original Size × 100%
PNG format uses DEFLATE compression algorithm with LZ77 and Huffman coding, providing lossless compression with transparency support. The converted files maintain full color depth and metadata while ensuring compatibility across all platforms and browsers.

📊 File Format Analysis
HEIC Input Format Details
High Efficiency Image Container (HEIC) is Apple's modern image format based on the HEVC/H.265 video codec. It provides superior compression efficiency compared to JPEG while maintaining higher image quality. HEIC files can contain:
- Single Images: Standard photographs with advanced compression
- Image Sequences: Live Photos and burst mode captures
- Auxiliary Images: Depth maps for Portrait mode effects
- Metadata: EXIF data, GPS coordinates, and camera settings
HEIC Compression Ratio = Original Raw Size / HEIC File Size ≈ 2:1 to 4:1
PNG Output Format Advantages
Portable Network Graphics (PNG) provides lossless compression with complete transparency support. Key benefits include:
- Universal Compatibility: Supported by all modern browsers and applications
- Lossless Quality: No compression artifacts or quality degradation
- Alpha Transparency: Full 8-bit transparency channel support
- Color Accuracy: Precise color reproduction with gamma correction
- Progressive Loading: Adam7 interlacing for gradual image display
PNG File Size = Image Dimensions × Color Depth × Compression Factor
Typical Compression: 10-40% size reduction from uncompressed
Typical Compression: 10-40% size reduction from uncompressed
🔧 Conversion Settings Impact
Quality Preservation
The conversion process maintains maximum quality by preserving the full color gamut and bit depth available in the source HEIC file. Since PNG uses lossless compression, no additional quality degradation occurs during the conversion process.
File Size Considerations
Converting from HEIC to PNG typically results in larger file sizes due to the change from lossy to lossless compression:
| Image Type | HEIC Size | PNG Size | Size Change |
|---|---|---|---|
| Standard Photo (12MP) | 2-4 MB | 8-15 MB | +200-300% |
| Portrait Mode | 3-6 MB | 10-20 MB | +250-350% |
| Screenshot | 500KB-2MB | 1-8 MB | +100-400% |
Color Space Handling
HEIC files may use extended color spaces like Display P3, which offers a wider color gamut than standard sRGB. During conversion, colors are mapped to the sRGB color space used by PNG, ensuring compatibility while maintaining visual accuracy across different displays.
