About Converting JFIF to PNG
JFIF is simply the standard container for JPEG image data — a .jfif file is a JPEG. Renaming or converting to .jpg makes it accepted everywhere. When you need to move away from JFIF, the usual reason is simple: unusual extension confuses some apps.
Converting your JFIF image to PNG solves that. PNG is a lossless raster image format that supports a full alpha-transparency channel. It is the standard choice for screenshots, logos, icons and any graphic with sharp edges or text where quality must be preserved exactly. In practice you gain lossless compression keeps every pixel intact and full alpha transparency. PrivConvert runs the whole JFIF-to-PNG conversion in server memory and deletes your file the instant the PNG is ready — nothing is stored, logged or reused.
