Cropper.js is an easy to use JavaScript/jQuery plugin for image cropping with support of live previews and custom aspect ratio.this plugin provide features move,zoom,rotate,Fully responsive and mobile-friendly.

The plugin displays a resizable grid layer on a given image allowing to visually resize and crop the image.

app/Http/Controller/ImageCropperController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ImageCropperController extends Controller

{

public function index()

{

return view('cropper');

}

public function upload(Request $request)

{

$folderPath = public_path('upload/');

$image_parts = explode(";base64,", $request->image);

$image_type_aux = explode("image/", $image_parts[0]);

$image_type = $image_type_aux[1];

$image_base64 = base64_decode($image_parts[1]);

$file = $folderPath . uniqid() . '.png';

file_put_contents($file, $image_base64);

return response()->json(['success'=>'success']);

}

}
