Export jpeg not as jpg

I imported jpeg photos from my IPhone using a Windows 11 computer. I've made edits to the photos in Lightroom Classic and now I want to export the photos to the same folder. When I do so, Lightroom converts them to jpg. So now I have the old photo jpeg and an edited photo jpg. There must be a setting so that I can put them back as jpeg. Jpg is old naming convention so I suspect there is a place I can change in Lightroom Classic Settings

I ran into the same problem as OP in slighlty different circumstances - I'm wanting to edit photos including changing the size during export, and I want the extension to be exactly the same as in the original photos (so that another software can identify them).

I've read the thread and understood that there is currently no way to resolve this since you can not select whether Lightroom uses .jpg or .jpeg in JPEG export. I wanted to put in my two cents and say that it would indeed be valuable to have that option available, since there are situations where the suffix matters.

This seems almost like a bug in LrC As @CarolynBall screen clip of Explorer shows, there are TWO files in the same folder with the same name but with JPEG and JPG extensions. One is the original and the other is the exported one where the OP exported to the same folder. The file size differences are to be expected from the export. The fact the references to industry standards say JPEG and JPG are the same is being ignored as the Operating System and LrC treat the files as two different files as they have different extensions. The bug is LrC in the export is saying it is going to export a JPEG but it exports a JPG. It happens on my Mac too.

Bob, I disagree with this, I don't see this as a bug. When we select "JPEG" in the Export dialog we are not explicitly selecting the file extension, but we are simply selecting the image format, after which LrC uses an appropriate valid extension (Jpg in this case, as it always has done). This is exactly the same when we select file type "TIFF" (LRC extension is Tif) or "JPEG XL" (extension is Jxl). The only "outlier" could be the new "AVIF" format where the extension is Avif (possibly because "Avi" is already taken).

I suppose someone could make a feature request to allow the user to specify the file extension when valid alternatives exist, but is that really needed?

IMHO, there's no need for that.

To me, how the OP wants to use LrC is against it's idea and principles. Of course, one can say, what the heck, simply make everything possible ... while I would also disagree with that.

I suspect the OP tries to use LrC in a way it is not designed for.

-> Not caring about originals and wanting LrC to replace originals with the edited ones.

That was my assumption also, though I don't believe that LrC would allow the original to be overwritten by the exported version even if the filenames (including extension) were the same. This is what happens when I tried:

As far as I know, jpg and jpeg are in fact the same. You can simply use both endings.

jpg is back from when Microsoft OS did only support 3 letters for file extensions.

... excerpt from the linked webpage:

JPGs and JPEGs are the same. The three-letter file extension was due to the limitations of older versions of Windows and MS-DOS. All file extensions were limited to three characters — today, this is no longer the case.

Odd - "jpg" isn't even an available string in the Image Format drop-down:

But in any event:

"There must be a setting so that I can put them back as jpeg. "

And this is it.

Yes, I have it set to JPEG but it converts it to a jpg as you can see below. Any other ideas? I was using LRC 12.4 and just updated to 13.0.2. That didn't change it.

No, not really - where are we looking, exactly?
