Image Resizer

NativePHP Mobile plugin that downscales images using native APIs — ImageIO on iOS and BitmapFactory on Android.

Install

composer require coyotito/image-resizer

Register the plugin it the NativeServiceProvider:

public function plugins(): array
{
    return [
        \Coyotito\ImageResizer\ImageResizerServiceProvider::class,
    ];
}

Usage

use Coyotito\ImageResizer\Facades\ImageResizer;

$ok = ImageResizer::resize(
    sourcePath: '/abs/path/to/source.jpg',
    targetPath: '/abs/path/to/target.jpg',
    maxSide: 1024,   // longest side cap; preserves aspect ratio, no upscale
    quality: 80,     // JPEG quality, 0-100
);

Returns true on success, false otherwise. Target is always written as JPEG. EXIF orientation is respected on both platforms.
