Image optimization via imagejpeg?

Question

PHP

there are all sorts
of console jpegtran, jpegoptim
there are
all sorts of external kraken and others,
but you can do this
imagejpeg($img, $new_img, $quality);
. At the output, it seems like a progressive jpeg and much smaller than the original, and Google stops cursing.
Are there any pitfalls in the case of imagejpeg?

Answer 1

Well, what underwater? there is no difference than to compress
, yes, jpegtran compresses everything as much as possible, but sometimes it is enough to set a lower quality to achieve the desired weight
