Answer : You can use filters with -webkit-filter and filter : Filters are relatively new to browsers but supported in over 90% of browsers according to the following CanIUse table: https://caniuse.com/#feat=css-filters You can change an image to grayscale, sepia and lot more (look at the example). So you can now change the color of a PNG file with filters. body { background-color:#03030a; min-width: 800px; min-height: 400px } img { width:20%; float:left; margin:0; } /*Filter styles*/ .saturate { filter: saturate(3); } .grayscale { filter: grayscale(100%); } .contrast { filter: contrast(160%); } .brightness { filter: brightness(0.25); } .blur { filter: blur(3px); } .invert { filter: invert(100%); } .sepia { filter: sepia(100%); } .huerotate { filter: hue-rotate(180deg); } .rss.opacity { filter: opacity(50%); } <!--- img src http://upload.wikimedia.org/wikipedia/commons/thumb/e/ec/Mona_Lisa%2C_by_Leonardo_da_Vinci%2C_from_C2RMF_retouched.jpg/500px-M...

Answer : imagealphablending( $targetImage, false ); imagesavealpha( $targetImage, true ); did it for me. Thanks ceejayoz. note, the target image needs the alpha settings, not the source image. Edit: full replacement code. See also answers below and their comments. This is not guaranteed to be be perfect in any way, but did achieve my needs at the time. $uploadTempFile = $myField[ 'tmp_name' ] list( $uploadWidth, $uploadHeight, $uploadType ) = getimagesize( $uploadTempFile ); $srcImage = imagecreatefrompng( $uploadTempFile ); $targetImage = imagecreatetruecolor( 128, 128 ); imagealphablending( $targetImage, false ); imagesavealpha( $targetImage, true ); imagecopyresampled( $targetImage, $srcImage, 0, 0, 0, 0, 128, 128, $uploadWidth, $uploadHeight ); imagepng( $targetImage, 'out.png', 9 ); Why do you make things so complicated? the following is what I use and so far...
