Notice: HEIF / HEIC (High Efficiency Image Format) supports animated frame sequences, but PNG (Portable Network Graphics) is a static image format. Converting an animated file will extract and save only the primary static frame.
Notice: Converting a lossy format (HEIC) into a lossless format (PNG) packages existing pixel data losslessly, but cannot restore visual details or artifacts discarded during original compression.
