Why should I convert an iPhone HEIC photo to PNG rather than JPG?
Converting HEIC to PNG provides a completely lossless output container. While converting to JPG applies a second round of lossy Discrete Cosine Transform compression, converting to PNG decodes the raw uncompressed RGB pixel matrix from the HEIC container and saves it using lossless DEFLATE compression. This preserves maximum dynamic range, eliminates compression artifacts, and supports alpha transparency layers from iOS Portrait Mode cutouts.
Key Takeaways
- Completely lossless output container: zero re-compression artifacting.
- Preserves Apple Portrait Mode cutouts and alpha transparency channels.
- Perfect for editing in Photoshop, Figma, Illustrator, and Premiere Pro.
- Batch convert up to 100 HEIC photos simultaneously with ZIP download.
