Responsive image resizing with srcset generation for Laravel.

Automatically resizes images to multiple WebP variants and generates <img> tags with srcset for optimal loading. Configurable image sources allow each project to define its own directories and URL structure.

Installation

composer require emiliolodigiani/laravel-images

Publish the config file:

php artisan vendor:publish --tag=images-config

Configuration

Define your image sources in config/images.php:

return [
    'quality' => 80,
    'widths' => [400, 800, 1200, 1920, 2500],
    'sources' => [
        'default' => [
            'originals'     => public_path('images'),
            'originals_url' => '/images',
            'sizes'         => public_path('images/sizes'),
            'url'           => '/images/sizes/{width}',
        ],
        // Add more sources as needed:
        'blog' => [
            'originals'     => storage_path('app/public/blog'),
            'originals_url' => '/storage/blog',
            'sizes'         => storage_path('app/public/blog-sizes'),
            'url'           => '/storage/blog-sizes/{width}',
        ],
    ],
];

Each source defines:

originals — absolute path to the directory with original images
originals_url — public URL prefix for originals (used as fallback when no resized versions exist)
sizes — absolute path where resized versions are stored (subdirectories per width)
url — public URL pattern for srcset ({width} is replaced with the actual value)

Usage

Blade component

<x-img src="photo.webp" alt="A photo" />
<x-img src="photo.webp" alt="A photo" sizes="(min-width: 768px) 50vw, 100vw" />
<x-img src="photo.webp" alt="A photo" source="guides" />

The component outputs an <img> tag with srcset and sizes attributes. If no resized versions exist, it falls back to the original.

HTML body helper

For rich text content with embedded <img> tags:

{!! responsive_images($model->body) !!}

This transforms all <img> tags in the HTML to responsive versions with srcset, sizes, and loading="lazy".

Resize after upload

The package does not handle file storage — your app saves files using Laravel's filesystem (Storage, Livewire storeAs(), controller store(), etc.). After saving, call ImageResizer::resize() with the absolute path to generate all resized versions.

The resize() method automatically detects which configured source the file belongs to based on its path.

use EmilioLodigiani\LaravelImages\ImageResizer;

// Livewire component
$this->photo->storeAs('', $filename, 'my-disk');
ImageResizer::resize(storage_path('app/public/photos/' . $filename));

// Controller
$request->file('image')->store('photos', 'public');
ImageResizer::resize(storage_path('app/public/photos/' . $filename));

// Downloaded from URL (e.g. MCP tool)
file_put_contents($path, Http::get($url)->body());
ImageResizer::resize($path);

Deleting images

Use ImageResizer::delete() to remove an image and all its resized versions:

ImageResizer::delete('photo.jpg', 'default');

Batch resize

Generate missing resized versions for all configured sources:

php artisan images:resize

Programmatic access

use EmilioLodigiani\LaravelImages\ImageResizer;

// Get available widths for an image
$widths = ImageResizer::availableWidths('photo', 'default'); // [400, 800, 1200, 1920]

// Get the public URL for a specific size
$url = ImageResizer::url('photo', 800, 'default'); // /images/sizes/800/photo.webp

How it works

When an image is resized, WebP versions are generated for each configured width that is smaller than the original
Images are scaled by their longer side (portrait images scale by height, not width)
A PHP manifest file at storage/framework/image-sizes.php tracks which sizes exist for fast lookup (no database queries)
The manifest is automatically updated after each resize operation and OPcache-invalidated for zero-downtime deploys

Customizing the view

Publish the Blade view to customize the <img> output:

php artisan vendor:publish --tag=images-views

The view will be at resources/views/vendor/laravel-images/components/img.blade.php.

Requirements

PHP 8.2+
