Is there such an app? Everything I've tried saves in png format only.
So I have to convert the files to jpg after saving the capture.

I tried Spectacle and Ksnip but they only support png!

I am on XFCE

JPEG is a lossy format. It makes sense for the raw capture to be done
in the highest-quality format available, in case you want to do some
processing on it before delivery.

Nemo has a plugin that will change that png to a jpg with one click. I've been doing
that, like forever.

As long as the subject is graphics what program may be used
to turn other formats into .webp the compression ratio is terrific
and they can be turned into .jpgs, etc. easily enough.

u don't want use the xfce tool in the task barre ?

Install Flameshot. This lets you choose the default format you want to
save to.

https://flameshot.org/

It's just the best there is IMHO.

xfce4-screenshooter

/* Read the preferences */
rc_file = xfce_resource_save_location (XFCE_RESOURCE_CONFIG, "xfce4/xfce4-screenshooter", TRUE);
screenshooter_read_rc_file (rc_file, sd);

That suggests, that whatever makes the call to the program, or perhaps
some preference setting, is making a PNG. The source code itself
does not suggest a complete ruling-out of JPG output.

You answered your own question. Since jpeg is a lossy format my jpg
files are often MUCH smaller than my png files and the only difference
I've found is the amount of disk space each format takes up. I don't
need a 954 KB (.png) screen capture when a 220 KB (.jpg) screen capture
is sufficient.

I have configured the native xfce4 screenshooter to capture in jpg.
I don't remember exactly how I did it but the file ../.local/share/applications/xfce4-screenshooter.desktop
contains the line "MimeType=image/jpeg;"

and the file
../.config/xfce4/xfce4-screenshooter
contains the line "last_extension=jpg"

Screen capture should be the job of XFCE
the desktop, or the windows manager, not
applications. Of course, applications can
hook itself to that function. I dunno how
Linux does things. :)

You answered your own question. Since jpeg is a lossy format my jpg files are often MUCH smaller than my png files and the only difference I've found is the amount of disk space each format takes up. I don't need a 954 KB (.png)
screen capture when a 220 KB (.jpg) screen capture is sufficient.

50% of the way down this page, is a comparison of JPG versus PNG capture. Screen captures never look good to begin with, You need as much quality preservation as possible, so that later, you can decide what to trade off
for storage purposes.

https://en.wikipedia.org/wiki/PNG # Garbage In Garbage Out --
# Always start your day, with a high quality image

The "pngcrush" utility can attempt to find a format within PNG, which
gives the smallest space consumption. For random screen captures,
it's not going to be worthwhile doing that. The "pngcrush" is used by
website operators, where controlled production of images
in the first place, produces an image that can be "represented efficiently". Then when you release "pngcrush" on it, you get that 5KB file you wanted.
For random screen captures, the savings might not be very significant.
PNGCrush is not a workflow as such. Only if you're an expert at image
prep (cartoon-like), is PNGCrush the icing on the cake.

I do a lot of my captures in PNG and then switch to GIF. This is good
for cartoon-like artwork with limited colors. Banding results if I take photographic pictures and try to make GIF from them (too many colors to quantize properly). Reluctantly then, I would switch to JPG.

But as a workflow, I don't have a problem with PNG for initial capture.
The capture compressor is likely set at 9 (in the ZIP sense) and is lossless. Modern processors can deal with the tiny object size, quite quickly.

Some of those PNG will be discarded, after the GIMP session. Now, if you
want a wasteful format, the GIMP native format takes 3-5MB or so, a lot
more than either PNG or JPG of the same thing.

God has already done that; It is called build essential. This command
will install it for you:

sudo apt install linux-headers-$(uname -r) build-essential dkms
