You need to use base64_decode(). AND. Sometimes it is not sufficient. Here is all code that you need: $img = $_POST[‘data’]; $img = str_replace(‘data:image/png;base64,’, ”, $img); $img = str_replace(‘ ‘, ‘+’, $img); $fileData = base64_decode($img); //saving $fileName=”photo.png”; file_put_contents($fileName, $fileData); P.S.
