    Best .png settings for software development

    Hello, I am having an issue with my png files showing dark outlines around my 16x16 icons. What are the best settings in Photoshop to avoid this. I currently am using the preset PNG-24

    Use PNG-32: 24 doesn't support alpha transparency. Also, do not double-post.

    It's reasonable to assume from the OP's comment that s/he was indeed using PNG32 already.
    People most often say PNG24 when they're actually talking about PNG32. This is largely, if not entirely, due to Adobe PS not actually listing PNG24 + 8-bit alpha transparency as PNG32.

    So, whilst it's, of course, technically correct that you make the distinction, it's a little pedantic in real terms.

    The synonymous use of PNG24 for PNG32 is likely to continue until Adobe see the error of their ways. In the meantime, it's a bit of a non-issue.

    I deleted his other post where he said about it being -24. I didn't know Adobe treated it like that: I've always used Illustrator to optimize my PNGs, where it is listed as PNG-32. Is he sure transparency is checked? What about a source PSD?
