Why Is My PNG So Large?
- PNG is a lossless format — it stores every pixel precisely. A HEIC photo that is 3MB may convert to a 15MB PNG because:
- HEIC uses very aggressive compression while maintaining quality
- PNG stores full pixel data without lossy compression
- The conversion to PNG unpacks all the compressed detail
- If the PNG file size is a concern, use Compress PNG after conversion to reduce it without visible quality loss, or convert to JPG instead.
