Turn .jfif files into .jpg files every app accepts, with zero quality loss: a JFIF already is a JPEG, so the image data is kept exactly as it is.
Drop JFIF images
Batch friendly. Each image is checked against the original, so you get the smallest file that still looks the same. Nothing is uploaded.
Many converters decode the JFIF and save a brand-new JPEG, which compresses it a second time and adds artefacts. That’s unnecessary: JFIF is the standard container for JPEG images, so the data inside is already a JPEG. In Lossless mode this tool keeps that data untouched and only gives the file a .jpg name.
Want the file smaller too? Switch to Smart mode and it will re-encode only if the result stays visually identical.
