Is there any drawback to using jpg instead of png for screenshots?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
OS: Kubuntu 18.04 with gnome-screenshot installed.
I ran these commands consecutively on the same desktop screen:
gnome-screenshot -p -d 10 -f /home/dkb/"GS$(date +%Y%m%d%H%M%S)".png
and
gnome-screenshot -p -d 10 -f /home/dkb/"GS$(date +%Y%m%d%H%M%S)".jpg
The difference in file size of the images is remarkable (to me):
dkb@kububb:~$ ll *.*g
-rw-rw-r-- 1 dkb dkb 703840 May 14 10:38 GS20180514103807.png
-rw-rw-r-- 1 dkb dkb 68749 May 14 10:38 GS20180514103820.jpg
dkb@kububb:~$
Yet, the two images appear to be indistinguishable to me:
Saving as .png
Saving as .jpg
Hence my question: why shouldn't I routinely save my screenshots in .jpg format as opposed to the .png which is usually the default?

The JPEG image in your question features visual artefacts easily noticeable with the naked eye that the PNG image doesn't contain. It becomes apparent when you open them both in separate tabs and switch between them via Ctrl+Tab.

PNG reproduces the original image exactly. JPEG reduces quality it in a way that, theoretically, you shouldn't notice in normal conditions (such as, when not zooming in).
PNG is usually recommended for screenshots because it still compresses fairly well unless the screenshot contains photographic or complex imagery. JPEG can be used if you are concerned about file size.
