Simple PHP script to help you convert your files to either base64 or percent encoded strings. Presumably for use in Data URIs, or otherwise embedding image data directly in another file/format.

<?php
 
if ($_FILES && $_FILES['uploadfile']) {
    header( "Content-type: text/plain; charset=UTF-8" );
    $fp = fopen( $_FILES['uploadfile']['tmp_name'], 'rb' );
    if ($_POST['base64']) {
        while (!feof($fp)) echo(base64_encode(fread($fp, 45))."\n");
    } else {
        $buf = '';
        while (!feof($fp)) {
            $buf .= rawurlencode(fread($fp, 120));
            while (strlen($buf)>=60) {
                echo(substr($buf,0,60)."\n");
                $buf = substr($buf,60);
            }
        }
        if ($buf) echo($buf);
    }
    fclose($fp);
    die();
}
 
?>
