Modular thumbnail generation, for CodeIgniter 4

Quick Start

  1. Install with Composer: > composer require tatter/thumbnails
  2. Update the database: > php spark migrate -all
  3. Register all handlers: > php spark handlers:register
  4. Load the service: $thumbnails = service('thumbnails');
  5. Create your first thumbnail: $thumbnails->create('bigfile.jpg', 'thumbnail.jpg');


The Thumbnails library uses CodeIgniter4's native Image class for fast and efficient processing. It also checks for modular support files so it can grow to cover anything you could possibly want to thumbnail: videos, 3D assets, text documents.


Install easily via Composer to take advantage of CodeIgniter 4's autoloading capabilities and always be up-to-date:

  • > composer require tatter/thumbnails

Or, install manually by downloading the source files and adding the directory to app/Config/Autoload.php.

Once the files are downloaded and included in the autoload, run any library migrations to ensure the database is setup correctly:

  • > php spark migrate -all

Pro Tip: You can add the spark command to your composer.json to ensure your database is always current with the latest release:

    "scripts": {
        "post-update-cmd": [
            "composer dump-autoload",
            "php spark migrate -all"

You will also need to register handlers for the library (see Tatter\Handlers):

  • > php spark handlers:register

Configuration (optional)

The library's default behavior can be altered by extending its config file. Copy bin/Thumbnails.php to app/Config/ and follow the instructions in the comments. If no config file is found in app/Config the library will use its own.


  • Load the service: $thumbnails = service('thumbnails');
  • Use the config file to define parameters, or change them on-the-fly:
  • Use create($input, $output) to write the thumbnail out to a convenient location: $thumbnails->create('bigfile.jpg', 'thumbnail.png');


The library looks across all namespaces for a Thumbnails/ directory and loads any supported classes it find. Each class defines the extensions it supports as well as its own create() method to generate the image. Add additional extension support from other modules, or write your own.

Note: This library will periodically update with new extensions, but we're also always glad for Pull Requests with additional extensions you might have.
