This re-saves a PNG using the strongest compression settings available and strips out metadata the picture itself does not need, such as the software that created it and the date it was made.
Every pixel comes out identical to the original. Nothing is approximated and nothing is thrown away, so the saving is modest compared with reducing the colours — typically a few percent to perhaps a fifth, depending on how the file was made in the first place.
If the result would be larger than what you gave it, the tool hands back your original untouched and says so, rather than pretending a bigger file is an improvement.

Questions
How much smaller will my file get?
Usually a few percent, occasionally much more if the file was saved inefficiently. If you need a large saving and the image is a screenshot or drawing, use the colour-reducing PNG Compressor instead.
It says the file is already as small as it can get.
That means our attempt came out bigger than your original, so you were given the original back. It was already well compressed.
