JFIF and JPG compatibility

JFIF is a common interchange structure for JPEG-compressed image data. Re-exporting it with a .jpg extension improves filename compatibility with apps and websites that do not recognize .jfif.

常見問題

Is JFIF the same as JPEG?

JFIF is a file interchange format that commonly contains JPEG-compressed image data.

Why is a quality control included?

JPG output uses lossy compression, so the control balances file size and visual quality.
