The file you get back from a WebP to JFIF conversion is a JPEG. That is what JFIF means, and it is why this conversion exists at all, because certain systems were written to accept that extension and will turn away anything else you send them.
Scanner utilities, document intake systems, and internal business software old enough that someone typed .jfif into a list of allowed extensions years ago and nobody has touched it since. It is rarely anyone's preference. It is a validator nobody has updated.
Since the output is JPEG underneath, an alpha channel has nowhere to go and transparent areas are filled with white. An animated WebP is reduced to its first frame. If either of those matters for your image, this is the wrong target and PNG will serve you better.
Plenty of people land here looking for a normal photo file and pick .jfif because it looked official. If nothing has specifically demanded that extension, choose JPG instead. You will get an identical picture with a name that every program on your machine recognises without argument.
The exact extension expected
Files come out named .jfif, which is what a strict validator is checking for.
Standard JPEG contents
Anything that can read a JPEG can read the file inside, whatever the name says.
Easy to switch to .jpg
The same picture can be run again to a normal extension if the rules change.
WEBP to AVIF Converter
Re-compress WebP images as AVIF, which is usually smaller again on detailed photographs.
GIF to JPEG Converter
Turn a GIF into a still JPEG image, keeping the first frame and filling transparency with white.
GIF to JFIF Converter
Write GIF images out as .jfif files for record systems and older applications.
GIF to AVIF Converter
Rewrite a GIF as a modern AVIF image, keeping the picture and dropping the 256 colour ceiling.
No. JFIF describes how JPEG data is stored in a file, and nearly every .jpg on your computer is a JFIF file underneath.
It is going by the name rather than the contents. Rename it to .jpg by hand and it will open immediately.
A little, since this is a second lossy pass. On a WebP that was not already compressed hard you would struggle to see it.
No, transparent areas are filled with white. There is no way around that with a JPEG based format.
