HEIC (High Efficiency Image Container) and PNG (Portable Network Graphics) are built for different jobs. HEIC is typically used for iphone and ipad photos, while PNG is best for logos, screenshots, web graphics with transparency. Converting lets you open, share or upload your files wherever PNG is expected.
