Limiting picture size (bytes)


Recommended Posts

You can't control PNG quality. It's a lossless file format, Unlike JPG, which will reduce the size, but reduces the quality. I don't know how PDNCrush would change the size, but i think it has to do with instead of saving pixels one by one, marking pixels' coordinates, and coding the coordinates into the PNG code. This would result in the picture rendering the pixels on the spot, instead of that they were included in the picture. At least, that's my theory, please coorect me if i'm wrong ;)

That's integrated in PDN. Just go to File>Save as, then from the drop down menu select ".jpg". After you typed in a name and clicked okay, a screen will appear where you can select the quality. 1 being the worst, and 100% being the best (still not lossless though...). Move the slider to change it.

hmm..it didn't reduce the size enough. are there other options?

if that doesn't work, how do i use JPG to reduce the quality? and in what program?

That's a little strange if you don't mind me saying. There are only two circumstances for PNGcrush/PNGout not to work; 1) it isn't a .png or 2) it's been crushed once already.

Very odd. But yes, Stephan is right in his guidelines for the JPEG quality dialog.

It will, but you won't be able to notice it at 95% quality (or 75% for that matter).

Not true. PNGCrush and the other programs take out the information that isn't needed. Here's an analogy: If you have 2 bold tags, it removes one of them to save space and keep the quality.
