PNG images are excluded from scaling after upload See ticket #48736. From the core: // Do not scale (large) PNG images. // May result in sub-sizes that have greater file size than the original. if ('image/png' !== $imagesize['mime']) { /* filter applied here */ }

The last parameter (false) is wrong, no boolean value accepted, it’s the “string $media” parameter, so either leave it out completely or define it properly.
