What to know about PNG compression

PNG uses lossless compression, so it is well suited to graphics, screenshots and images where preserving exact pixel information matters.

PNG file size depends heavily on the image contents and how the file was originally encoded. Because of that, reprocessing a PNG does not guarantee a smaller file.

Kyvorix shows the actual resulting size instead of claiming a fixed percentage reduction.

Transparent images PNG supports transparency, and this tool does not intentionally replace transparent pixels with a background.

Already optimized files A PNG that has already been optimized may show little or no size reduction.

Screenshots PNG is often useful for screenshots and graphics containing sharp edges or text.
