Smaller fileBest quality
Compress a PNG to under 50KB in your browser — transparency kept, nothing uploaded.
50KB is tight for a PNG. Icons, logos and simple graphics reach it with room to spare. A screenshot usually gets there too, though fine gradients may show slight banding once the colour count comes down.
PNG is a lossless format, so unlike JPEG there is no quality slider to turn down — saving at “lower quality” produces a byte-identical file. What a PNG actually pays for is the number of distinct colours it contains. This tool reduces the colour count until the file fits your target, and only reduces the pixel dimensions if colour reduction alone cannot get there. Transparency is preserved either way.
For photographs, JPEG at the same file size will almost always look better. PNG is the right choice when you need transparency or crisp flat colour — logos, icons, screenshots and diagrams.

Yes. Transparency is preserved; only the number of colours is reduced, and the dimensions only if that is not enough to reach the target.
The PNG format is lossless, but reaching a fixed size means reducing the number of colours, which does change the image. For photographs, JPEG at the same file size will usually look better.
