use Mostafaznv\PdfOptimizer\Enums\ColorConversionStrategy;
use Mostafaznv\PdfOptimizer\Enums\PdfSettings;


# input pdf file path
$file = 'path/to/large.pdf';

# output (optimized) pdf file path
$optimized = 'path/to/optimized.pdf';


# optimizing the pdf file
$result = PdfOptimizer::init()
    ->settings(PdfSettings::SCREEN)
    ->colorImageResolution(60)
    ->colorConversionStrategy(ColorConversionStrategy::DEVICE_INDEPENDENT_COLOR)
    ->optimize($file, $optimized);


# check result
if ($result->status) {
    echo "PDF file optimized successfully!";
