i've tried above code, not giving me output, please help. in advance.

the code pointless. have png inside data uri, there zero point in loading png gd, re-compressing png. that's massive waste of ram , cpu time accomplish nothing.

also, gd doesn't understand data uris, cannot feed uri gd functions , expect useful happen.

you have png, need this:

$b64_png = string_operation_to_extract_base64_data_from_data_uri($datauri); header('content-type: image/png'); echo base64_decode($b64_png);
