pronoob5 Posted July 8, 2007 Share Posted July 8, 2007 I am trying to submit a picture to a website, and they have a byte and size requirement. I have met the size requirement, but now i need to find a way to lower the amount of bytes the picture is... Suggestions? Quote Link to comment Share on other sites More sharing options...
usedHONDA Posted July 8, 2007 Share Posted July 8, 2007 Well if you're using a PNG, use a program like PNGOut or PNGCrush to reduce the size of your files without loosing any quality.

PineappleQc Posted July 8, 2007 Share Posted July 8, 2007 Yes, I think PNG "quality control" just like when saving is supposed to come soon... However, I'm not part of the Dev team so I can't really confirm anything.

Stephan Posted July 8, 2007 Share Posted July 8, 2007 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 Quote Link to comment Share on other sites More sharing options...
pronoob5 Posted July 8, 2007 Author Share Posted July 8, 2007 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? Quote Link to comment Share on other sites More sharing options...
Stephan Posted July 8, 2007 Share Posted July 8, 2007 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. Quote Link to comment Share on other sites More sharing options...
Myrddin Posted July 8, 2007 Share Posted July 8, 2007 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).

usedHONDA Posted July 8, 2007 Share Posted July 8, 2007 ...You can't control PNG quality... 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.

Stephan Posted July 9, 2007 Share Posted July 9, 2007 I don't know for sure if that is the actual method though... Do we have a professional here in the forums? Quote Link to comment Share on other sites More sharing options...
Bob Posted July 9, 2007 Share Posted July 9, 2007 What do you mean by 'the actual method'? How to reduce filesize efficiently or how PNGCrush works? Quote No. Way. I've just seen Bob. And... *poof!*—just like that—he disappears into the mist again. ~Helio Link to comment Share on other sites More sharing options...
