What Is PNG to HEIC Conversion?

PNG is a lossless image format widely used for graphics, screenshots, transparency, and web content. It preserves image detail but can produce large files, especially for photos.

HEIC is a High Efficiency Image Container format designed to store high-quality images in smaller files on compatible devices and software. Converting PNG to HEIC can reduce file size, but compatibility is more limited than PNG.
