Once again, read the manual:
http://www.php.net/imagepng
bool imagepng ( resource $image [, string $filename [, int $quality [, int
$filters]]] )
quality
Compression level: from 0 (no compression) to 9.
(5.1.2 Added the quality parameter.)

Yes, it's possible. The quality will suffer offcourse, it all depends on
your needs wether this is acceptable.
