She’s a real cutie.

Yeah, no. Lots of words, yet it misses the mark. This image isn’t so big because it’s saved as a png, it’s so big because it was saved badly as a png. That’s the explaination. I just saved it and re-saved it, recompressed it (still as png), and ended up with 120kb with no particular effort to tweak anything whatsoever.
 
I personally consider PNG the best format for drawn images. JPG’s shinking sizes come from it doing math to the image to convert it into waves (in a conversion that can go both ways, so it is then possible to turn those waves back into an image for you to see), then seeing which of those waves aren’t very pronounced and trimming them out. This process introduces artifacts, since you are in fact removing information, even if it first goes after the information least affecting the image (you can crank up how aggressive it is). The artifacts usually aren’t visible at all unless you go really hard on the compression… in the intended use case of jpgs which is photos. Nice and clean images generated inside a computer, using large swathes of literally the same color (which are actually the perfect artifact breeding ground for jpgs instead of being an easy to handle thing in pngs)? PNG usually handles that great, and it’s actually a lossless format so no artifacts, guaranteed.

thanks for the facts, it was something that really intrigued me

@Josedx9 , it’s all about file types, their strengths, and their weaknesses. This image was saved as a .PNG, which is probably the second worst choice for an image like this (.BMP being the absolute worst). The .PNG format works best when there is a limited number of colors in the image. This image has a TON of unique colors, so the compression routines used by the .PNG format backfired and resulted in an abnormally large file.
 
Just saving this image as a .JPG shrinks it down to ~180 KB. The JPG format EXPECTS a lot of unique colors, and thus works best with images like this one. There are also additional parameters and features of the .JPG format that many editors don’t support that can result in even better savings. For example, with GIMP’s ability to tweak those hidden parameters I was able to shrink this image to ~99 KB without loss of quality.
 
On a side note: this sort of thing isn’t common knowledge, so nobody should feel bad about not understanding it. I do programming as a hobby, so I ended up learning studying how these formats work in some detail.

@Scorpion  
yes well, but why does it weigh so much then? That’s what I do not understand.  
for example, this pic >>2017564 weigh 1.56 MB and it has more resolution, but this weighs more and it is much smaller lol

@Josedx9  
because it is not the full res ;3

Ohh…

I do not understand how this is, the drawing weighs 1.89mb but the resolution is quite poor lol

after having to handle a alicorn foal for so long you wouldd wonder where she couldnt sleep :D

She’s her usual beautiful & sexy self, of course, but all I can focus on is how uncomfortable that looks. Her shoulders are going to give her hell when she wakes up.

She’s so majestic when asleep!
