How PNG to HEIC Conversion Works
The Portable Network Graphics format uses lossless DEFLATE compression and supports a full alpha-transparency channel, preserving every pixel exactly as encoded. Converting to HEIC produces an image file that applies H.265 (HEVC) intra-frame compression achieving roughly twice the efficiency of JPEG at equal visual quality, used natively by Apple devices. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. This makes HEIC the practical choice when the destination system requires it or when the target format offers better compatibility or compression. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
