How would I convert the png to geotiff using the .json metadata?

[islandtriumph96]

does this look pretty accurate? https://www.rainviewer.com/api/geotiff.html#:~:text=It%20is%20quite%20easy%20to%20convert%20a%20PNG,-co%20compress%3Dlzw%20-of%20Gtiff%20-a_srs%20EPSG%3A3857%20%7Bsource_image%7D%20%7Boutput_image%7D

I am also trying to see if geotiff can then be converted to a different format, say NAIP.
