Note that PNG compression is different from JPG compression. See https://imagemagick.org/script/command- ... hp#quality.

What format is your input? If it is compressed highly such as JPG, you will not be able to get a PNG compression to the same file size.

Please say a bit more about your input. Or provide the input image. Or provide the information about it from identify -verbose yourimage

PNG does not support JP2000 compression.

Please do not double post. I have deleted your duplicate post.
