Some upload forms and older mail clients specifically expect the .jfif extension. This tool re-encodes your PNG as a standard JPEG stream written with the JFIF extension, so the file passes those checks while staying a normal photo.
Drop your PNG file above and Morphix decodes it locally, then re-encodes it as JFIF using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
