README

This package is the Laravel 6.0 and up specific integration of spatie/image-optimizer. It can optimize PNGs, JPGs, SVGs and GIFs by running them through a chain of various image optimization tools. The package will automatically detect which optimization binaries are installed on your system and use them.

Here's how you can use it:

use ImageOptimizer;

// the image will be replaced with an optimized version which should be smaller
ImageOptimizer::optimize($pathToImage);

// if you use a second parameter the package will not modify the original
ImageOptimizer::optimize($pathToImage, $pathToOptimizedImage);

You don't like facades you say? No problem! Just resolve a configured instance of Spatie\ImageOptimizer\OptimizerChain out of the container:

app(Spatie\ImageOptimizer\OptimizerChain::class)->optimize($pathToImage);

The package also contains a middleware to automatically optimize all images in an request.

Don't use Laravel you say? No problem! Just use the underlying spatie/image-optimizer directly.

Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

Installation

You can install the package via composer:

composer require spatie/laravel-image-optimizer

The package will automatically register itself.

The package uses a bunch of binaries to optimize images. To learn which ones on how to install them, head over to the optimization tools section in the readme of the underlying image-optimizer package. That readme also contains info on what these tools will do to your images.

The package comes with some sane defaults to optimize images. You can modify that configuration by publishing the config file.

php artisan vendor:publish --provider="Spatie\LaravelImageOptimizer\ImageOptimizerServiceProvider"

This is the contents of the config/image-optimizer file that will be published:

use Spatie\ImageOptimizer\Optimizers\Svgo;
use Spatie\ImageOptimizer\Optimizers\Optipng;
use Spatie\ImageOptimizer\Optimizers\Gifsicle;
use Spatie\ImageOptimizer\Optimizers\Pngquant;
use Spatie\ImageOptimizer\Optimizers\Jpegoptim;
use Spatie\ImageOptimizer\Optimizers\Cwebp;

return [
    /**
     * When calling `optimize` the package will automatically determine which optimizers
     * should run for the given image.
     */
    'optimizers' => [

        Jpegoptim::class => [
            '-m85', // set maximum quality to 85%
            '--strip-all',  // this strips out all text information such as comments and EXIF data
            '--all-progressive'  // this will make sure the resulting image is a progressive one
        ],

        Pngquant::class => [
            '--force' // required parameter for this package
        ],

        Optipng::class => [
            '-i0', // this will result in a non-interlaced, progressive scanned image
            '-o2',  // this set the optimization level to two (multiple IDAT compression trials)
            '-quiet' // required parameter for this package
        ],

        Svgo::class => [
            '--disable=cleanupIDs' // disabling because it is known to cause trouble
        ],

        Gifsicle::class => [
            '-b', // required parameter for this package
            '-O3' // this produces the slowest but best results
        ],
        
        Cwebp::class => [
            '-m 6', // for the slowest compression method in order to get the best compression.
            '-pass 10', // for maximizing the amount of analysis pass.
            '-mt', // multithreading for some speed improvements.
            '-q 90', //quality factor that brings the least noticeable changes.
        ],
    ],

    /**
     * The maximum time in seconds each optimizer is allowed to run separately.
     */
    'timeout' => 60,

    /**
     * If set to `true` all output of the optimizer binaries will be appended to the default log.
     * You can also set this to a class that implements `Psr\Log\LoggerInterface`.
     */
    'log_optimizer_activity' => false,
];

If you want to automatically optimize images that get uploaded to your application add the \Spatie\LaravelImageOptimizer\Middlewares\OptimizeImages::class in the http kernel.

// app/Http/Kernel.php
protected $middlewareAliases = [
   ...
   'optimizeImages' => \Spatie\LaravelImageOptimizer\Middlewares\OptimizeImages::class,
];

Usage

You can resolve a configured instance of Spatie\ImageOptimizer\OptimizerChain out of the container:

// the image will be replaced with an optimized version which should be smaller
app(Spatie\ImageOptimizer\OptimizerChain::class)->optimize($pathToImage);

// if you use a second parameter the package will not modify the original
app(Spatie\ImageOptimizer\OptimizerChain::class)->optimize($pathToImage, $pathToOptimizedImage);

Using the facade

use ImageOptimizer;

// the image will be replaced with an optimized version which should be smaller
ImageOptimizer::optimize($pathToImage);

// if you use a second parameter the package will not modify the original
ImageOptimizer::optimize($pathToImage, $pathToOptimizedImage);

You don't like facades you say? No problem! Just resolve a configured instance of Spatie\ImageOptimizer\OptimizerChain out of the container:

app(Spatie\ImageOptimizer\OptimizerChain::class)->optimize($pathToImage);

Using the middleware

All images that in requests to routes that use the optimizeImages-middleware will be optimized automatically.

Route::middleware('optimizeImages')->group(function () {
    // all images will be optimized automatically
    Route::post('upload-images', 'UploadController@index');
});

Adding your own optimizers

To learn how to create your own optimizer read the "Writing custom optimizers" section in the readme of the underlying spatie/image-optimizer package.

You can add the fully qualified classname of your optimizer as a key in the optimizers array in the config file.

Example conversions

Here are some example conversions that were made by the optimizer.
