Rolen47 Posted November 30, 2009 Share Posted November 30, 2009 It would be incredible if Paint.NET was able to save in this rare format. Very few programs will save PNGs in this 8bit+alpha format, there are only 3 that I know of: Fireworks (ridiculously expensive) pngnq (command line) pngquant (command line) What's the advantage of 8bit+alpha? Well I'll show you (this may not look right in some old browsers): Original 32bit PNG (81.7 KB): Big filesize, but it has nice semi-transparent edges. 8bit PNG (27.6 KB): The image is much smaller in filesize, however you'll notice that without an alpha channel it looks like a cut-out sticker. 8bit PNG+alpha (27.9 KB) Sweet, the best of both worlds. It has a small filesize and at the same time it has semi-transparent edges that look faded, just like the original 32bit image. I noticed that Paint.NET can open 8bit+alpha PNGs no problem, but would it be difficult to program it to allow it to save in this format?

Rick Brewster Posted November 30, 2009 Share Posted November 30, 2009 I don't have any plans to add this to Paint.NET. Like you said, it's a rare format. If you really really need to squeeze images down to that size, you should work with them at 32-bit and then squish them to the 8-bit+A format as a final post-processing / pre-uploading step.

david.atwell Posted December 1, 2009 Share Posted December 1, 2009 Filesize can also be greatly improved by OptiPNG, a plugin for Paint.NET. Your posted image, optimized in OptiPNG down to 28.48 KB, is attached. :-) Nice and semi-transparent edges and everything, though you'll have to click through the preview to the final to see it.
