About the formats
JFIF files are ordinary JPEG images with a different extension, often saved that way by Windows or Chrome. Some sites reject the .jfif extension even though the data is a JPEG.
PNG is a lossless image format with transparency. It is ideal for screenshots, logos and graphics, but photos saved as PNG are much larger than JPG.
