Hey all~
So, rather than try and browse through past threads to potentially find an answer, I thought I'd just make something new to ask this x3
I recently finished my next batch of comics, but the only problem is that a few of them are big. Like, really big. Like, too big that they failed all my usual methods of getting them under 200KB big.
The process I use right now is I open each comic in Photoshop and use the "Save for Web" feature; I reduce transparency and dither, and from there I reduce the amount of colors until I get under that 200KB limit. Not to say that it's been an easy process, or one that always spares quality, but it's always worked out in the end before. But now I've got comics that are easily 20+ panels, some with lighting and color effects, and my current method cannot get them anywhere near 200KB without making them unreadable.
Does anyone have other tips on reducing file size for the NT? Any creative ideas or suggestions? Any idea whether this is truly a worthy endeavor? xD

Twillie I have more than one way to get a file size down, but what I'd really like to do is work with the file itself. If you're comfortable with it, could you PM a copy of your biggest comic, and I can play around with it? I have ideas, but I'm more used to working with black and white, and I don't know how color affects those things. Anyway, in the meanwhile, here's some quick tips. - I assume you're already saving as a .gif, correct?
- Try making the comic less than 470px wide. Shaving off 5/10 pixels in width (by scaling it down so the length changes at the same ratio) doesn't change the look very much, but it can help push you under the edge.
- As a last resort, you could also cut the comic in half and submit it as two different parts.
Those are the basic tips, I have more advanced tips that involve more technical manipulation that's trickier to explain. But let's see if these work first.

Yeah, I can send a file your way if you'd like to play around with it! As for other tips, they're being saved as gifs yeah, and I may just play around with shaving off some width, see if that helps! And yeah, that was an idea that came to mind to me too, if I may have to cut them in half. Hopefully with the comics that need it, it'd make sense for them, but eh I guess that's the dilemma of weekly updates vs accessing it all at once in general xD

Okay, so after some playing around, I managed to get it under 200kb. Here's how I did it. - I brought the .png Twillie gave me into GIMP
- On the top menu bar, I went to image>mode>indexed (It was defaulted to RGB)
- A popup called "Indexed Color Conversion" appeared. On Ink, I choose the "Use black and white (1-bit) palette"
- For Twillie's, I tried black and white first, to make sure it could be brought down, and it was 59kb. then I tried "Use Custom Palette" and selected Web, and checkmarked "Remove unused colors from colormap," and that brought it up to 169. So I then chose "Generate optimum palette" and set "Maximum number number of colors" to 12
- Dithering is set automatically to "None"
- I exported as a .gif, and saw that now it was over 200kb.
- After some adjustments, I found the optimal number of colors was 8, at 195kb
In Photoshop, wow, it's exactly the same, that was easy. Except I like GIMP's end-product better, it show the gradient a little more in the last panel.

Thank you for your advice June, I've been trying it out on my comics and so far it's been successful! Tbh if the file I sent you can be brought to 200kb, any of these comics can, so hopefully it'll be smooth sailing from here x3 I'm really appreciative of the help, this got me past a roadblock I didn't know how to pass on my own :3
