ตัวแปลงไฟล์ออนไลน์ฟรี JFIF เป็น PICON

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.

This format is used to store small personal icons. It is used in website development to create favicons that are displayed in the address bar of the web browser as well as in satellite TV for identifying broadcast channels. It is very similar in structure to a GIF format image.
