無料オンラインJFIFからHEICへのコンバーター

JFIF is a graphical data format that enables the exchange of compressed JPEG files between computers. The main feature of the format is the use of a marker to indicate parameters that are not used in the JPEG standard, namely, pixel geometry, pixel size and some other parameters.

HEIC is a file extension that Apple uses for the HEIF image format, which are usually coded by HEVC codec (High Efficiency Video Compression). This format is great for Live Photos because it can contain an image sequence. The best part about it is that you can store twice as many pictures in the HEIC format as in JPEG in the same size and quality because it uses the next-generation file compression.
