uploading png image is increasing it's size than the original

[Kiransai-webonise]

$image = Image::make($img->path());
$image->save($img_name, 70);

Above piece of code is working fine for jpg images but when i upload png image its size is increasing. Am I doing anything wrong or it is an issue?

Same issue here
I'm uploading an png at 29.9MB

and I'm doing that

        $manager = new ImageManager([
            'driver' => 'imagick',
        ]);
        $img     = $manager->make($absolutePath);
        $img->save($absolutePath, 10);

and the final weight is 34,6MB

Error still exists...
My "minified" images have a bigger filesize even though I resized images bei 70%.
Any ideas how to fix?
