Spriters and Pixel Artists or anyone in between!
I just need to know if there's a program or something that could optimize this picture :
I want the biggest one to be as "good looking" as the first one. What I mean is, in the 2nd one, you can see the pixels much more compared to the first one. I'd like to know if there's a program or something that could optimize those pixels without me having to manually fixing it.

This is a really good blurring technique:

FWIW, I have now made this into a custom GMIC filter (thus, interactive preview etc.)
It still needs to support multi-layer application (for animations).
Anyway I'll give the current definition here, as it's short:
#@gimp Antialias: antialias, antialias #@gimp : note = note("* finetuning") #@gimp : Detail preservation = float(.30,0,1) #@gimp : Smoothing = float(8,0.5,1024) #@gimp : Sharpness = float(.4,0.001,1) #@gimp : Iterations = int(2,1,32) #@gimp : Gradient Smoothing* = float(0,0,10) #@gimp : Tensor Smoothing* = float(0.5,0,10) #@gimp : Fast Approximation* = bool(1) #@gimp : DoG base* = float(0.05,0.001,100) #@gimp : DoG distance* = float(0.05,0.001,100) #@gimp : DoG threshold* = float(20,0.0001,49.999) # # # XXX some way to adjust DoG parameters antialias : -repeat @# -l[@{>}] --gimp_dog[-1] $8,{$8+$9},$10,1,0 # -2? -> -1? -input [-2]x1 -repeat $4 -smooth[-1] $2,$3,1.0,$5,$6,.8,30,2,0,$7 -done # # sanitize the DOG layer for masking use -normalize[-2] 0,1 -apply_curve[-2] 1,{93/255},{.73-.73*$1},{192/255},{192/255} -image[-3] [-1],0,0,0,0,1,[-2] -remove[-2,-1] -endlocal -done
Paste that into the file ~/.gmic and restart GIMP in order to try it, if you are curious.
Make sure to leave that final blank line in.
EDIT:
I just fixed multi-layer application; here's an overly enthusiastically applied example based on a RagnarokOnline animation:
Original:
Smoothed:
(if this was an animation I was actually making, I'd draw some of the sharpness (eg sleeves) back in as needed)
EDIT2:
Here is a better example:
(zoom helps 
(parameters: smooth = 2 sharp = 0 detail = .2 iterations = 1 gradsmooth = .7 tenssmooth = .5)
The current default settings are pretty good, but I'm sure there are better -- If you think you've found better defaults I'd like to hear about it
I think that looks much better the hq2x
None of them are working right now, downloaded both GMIC and Hq2x but none work 
. I don't think I went on the wrong website...lol...which websites did you download the programs from?
Wait a minute, downloaded the wrong thing >_>. I was actually on the wrong website, lol.
That is blurring though - no scaling is going on. Try scaling then applying that blur if you want a relevant comparison.
I guess. I need to get the plugin working to see how it scales.
True, Infernal, would you happen to know how to add the code to GIMP so I can blur the picture.
and can anyone send me the link to the hq2x website thingy, google is not being friendly.
not sure how good it is or anything all i could find though : http://code.google.com/p/hqx/
There are 10 types of people in this world - Those who understand Binary and those who don't.
It sadly does not work for me . Thanks anyways.
Well as far as automated sizing goes, you're just looking at testing out different filters. Since that is pixel art, you might want to try some more specialized filters:
