Usage

Using the Facade

use MiniPNG\LaravelMiniPNG\Facades\MiniPNG;

// Compress an image
$result = MiniPNG::compressImage('https://example.com/image.jpg');

// Convert image format
$result = MiniPNG::convertImage('https://example.com/image.jpg', 'webp', 90);

// Compress PDF
$result = MiniPNG::compressPdf('https://example.com/document.pdf');

// Convert PDF to images
$result = MiniPNG::convertPdfToImages('https://example.com/document.pdf', 'high', 'jpg');

// Get user profile
$profile = MiniPNG::getProfile();

Using Dependency Injection

use MiniPNG\LaravelMiniPNG\Contracts\MiniPNGInterface;

class ImageController extends Controller
{
    public function __construct(private MiniPNGInterface $minipng)
    {
    }

    public function compress(Request $request)
    {
        $result = $this->minipng->compressImage($request->input('image_url'));
        return response()->json($result);
    }
}

Using the Service Container

$minipng = app('minipng');
$result = $minipng->compressImage('https://example.com/image.jpg');

convertImage(string $sourceUrl, string $outputFormat, ?int $quality = null): array

Convert an image to a different format.

// Convert to WebP with 90% quality
$result = MiniPNG::convertImage('https://example.com/image.jpg', 'webp', 90);

// Convert to PNG with default quality

$result = MiniPNG::compressPdf('https://example.com/document.pdf');

convertPdfToImages(string $sourceUrl, ?string $imagesQuality = null, ?string $imagesFormat = null): array

Convert a PDF document to a set of images (one per page).

// Convert to high-quality JPG images
$result = MiniPNG::convertPdfToImages('https://example.com/document.pdf', 'high', 'jpg');

// Convert to medium-quality PNG images (default)
$result = MiniPNG::convertPdfToImages('https://example.com/document.pdf');
