Hi,

I use transparent png every project.My Png exports could be big sizes sometime so I want reduce file size them. i've found useful web site tinypng.org .It realy reduces my png about %40-%70 without any quality change.

You could get more performance with reduce size.I cant test performance because my game runs 60 fps on chrome it was same after reducing guero2013-05-19 17:26:42

Not sure you gain performances (since all pictures are uncompressed before be used)

But yes, smaller pictures are good for smaller download

And that is why you shall respect the bug reports guidelines, not only giving a capx is making the bug reproductible in one click in a situation they can work with (less time wasted trying to reproduce vague instructions) but also it helps filtering false positives.

Game design is all about decomposing the core of your game so it becomes simple instructions.

PNG compression won't affect performance.

Actually Construct 2 has the best image compression pipeline I've ever seen in a game dev tool. I recommend changing your images to png-8 in the image dialog and then brute compressing on export. That is effectively doing what TinyPNG does.
