Oh please god don't switch to .jpg
Yes, I registered on these forums expressly for the purpose of telling you how horrible of an idea that is. (which should clue you in about just how horrible that idea is)
Jimor:
Unless of course, the artist himself says that it would look better for THIS PARTICULAR COMIC.
Believe it or not, there are occasions when an inferior tool produces a superior result because it fails in a specific way that enhances the artistic effect, or does one specific thing better than an overall better tool.
zmeiat_joro:
So why not just convert that part of the comic to jpeg and then paste it back to the png?
Jimor:
That depends on what the issue is. If it's the artifacting you see in the comic now, it wouldn't do any good to paste a non-artifacting segment in that then gets compressed back to the artifacting version. If it's a different compression effect that happens to look cool, there's still no guarantee that it will survive the addition of the PNG compression. Somebody suggested a non-lossy PNG compression, which might work, I dunno.
Still, it's the people having kittens about converting ONE comic to .jpg as if it was going to destroy civilization as we know it that are just being ridiculous. The .jpg is the version Jeph prefers, END OF STORY.
bicostp:
As long as he uses a fairly high quality level of JPEG compression, rather than whatever MS Paint spits out, it shouldn't be too noticeable. Even the existing settings would look better if there was some dithering to imitate the gradients better (it's kind of obvious that there is none, hence the big bands of color on the lightning glow), however that might cause stray pixels to show up on solid colors without some manual pallet tweaking.
Copying the JPEG compressed version into an 8 bit .PNG would just add the JPEG artifacts on top of the fixed-pallet dithering.
EDIT: At 85% quality (below that you start seeing compression artifacts at 100% zoom), today's comic comes in at 410k. In PNG-24 (lossless), it's 419k.
