Imager is a Craft plugin for doing image transforms, optimizations and manipulations. It does all the things that the built-in image transform functionality do – and so much more.

🌱 Using Imager X inside Twig templates? 🌱 You'll probably also want The Power Pack. It's free, and gives you a set of convenient Twig functions that replace those long, fiddly blocks of <picture> markup with a single function call – with all the responsive image best-practices built in. Optimal images, less code, less cognitive load.

🤖 Coding with an AI agent? 🤖 Imager X Skills teaches your coding agent how Imager X actually works – the quick transform syntax, named transforms, automatic generation, and how to build proper <picture> markup with the Power Pack. Written from the plugin source, so you get transforms that work instead of plausible-looking guesses. It's free, and installs into Claude Code, Cursor, Copilot and others.

✨ New ✨ AI Image Editor lets your editors retouch and generate image assets directly in the Craft control panel, just by describing what they want in plain words – "make the background white", "remove the coffee cup", "make it look like golden hour" – and iterating until it looks right. No fixed filters, no round-trips to a desktop editor, no leaving Craft. Visit the website to learn more! 🪄

Features

The most efficient template syntax for doing a bunch of image transforms in one go.
{{ craft.imager.transformImage(myImage, [800, 2000, 16/9]) | srcset }}
Transforms are completely file based, no database queries needed.
Transform Assets (local and cloud-based ones), local images, external images, or even the transformed images themselves.
Or offload all your transforms to third party services with first party extensions for Cloudflare, Bunny, Imgix, AWS serverless, Imagekit and Imageboss. Or, write your own transformer to use whichever method/service you'd like. (PRO)
Upload and serve transforms from Amazon S3 or Google Cloud Storage. Or, write your own storage interface to use whichever cloud service you want. (PRO)
Support for modern image formats like WebP, AVIF and JPEG XL.
Optimize your legacy format images with jpegoptim, jpegtran, mozjpeg, optipng, pngquant, gifsicle, TinyPNG, Imagemin or Kraken. Or, write your own optimizer interface for whichever post-optimization tool or service you want.
Auto generate transforms on Asset upload or when saving elements. (PRO)
Console commands for batch generating transforms. (PRO)
A nifty utility for clearing caches, batch generating transforms (PRO), and debug information.
GraphQL support. (PRO)
Transform any type of input data that can be represented as an image using file adapters.
Support for interlaced/progressive images.
Support for animated gifs.
Support for fallback images when Assets are missing, or completely replacing all images with a placeholder one (especially useful in development).
If you know the aspect ration you want, you don't have to calculate the extra height/width.
{ width: 800, ratio: 16/9 }
New letterbox resize mode.
{ width: 600, height: 600, mode: 'letterbox', letterbox: { color: '#000', opacity: 0 } }
New croponly mode. To crop, not resize.
{ width: 600, height: 600, mode: 'croponly', position: '20% 65%' }
New cropZoom parameter for when you want to get a little closer.
{ width: 600, height: 600, mode: 'crop', position: '20% 65%', cropZoom: 1.5 }
Basic image effects, including grayscale, negative, blur, sharpen, gamma and colorize.
{ effects: { sharpen: true, gamma: 1.4, colorize: '#ff9933' } }
Advanced image effects, including color blend, tint, clut, levels, sepia, contrast, modulate, normalize, contrast stretch, unsharp mask, posterize and many more (Imagick imagedriver only).
{ effects: { modulate: [100, 40, 100], colorBlend: ['rgb(255, 153, 51)', 0.5] } }
Your own choice of which resize filter to use. Speed vs. quality is up to you (Imagick imagedriver only).
Support for watermarks.
{ watermark: { image: logo, width: 80, height: 80, position: { right: 30, bottom: 30 }, opacity: 0.8, blendMode: 'multiply' } }
Lots of placeholder options, even the brand new blurhash thingy.
Get color information, dominant color and palette, from your images.
A bunch of color utilities for getting brightness, hue, lightness, percieved brightness, relative luminance, saturation, brightness difference, color difference and (puh!) contrast ratio.

First party plugins

In addition to receiving first-party support, these plugins also works as an example on how to extend Imager X with your own transformers, external storages, file adapters, optimizers and effects.

Upgrading from Imager X 5.0 to 6.0

In Imager X 6.0, some functionality with external dependencies has been extracted into separate plugins. If you were using any of these features in 5.0, you will need to install the corresponding plugin(s):

Feature	Plugin	Composer package
Imgix transformer	Imager X Imgix Transformer	`spacecatninja/imager-x-imgix-transformer`
AWS S3 external storage	Imager X AWS Storage Driver	`spacecatninja/imager-x-aws-storage-driver`
Google Cloud Storage	Imager X GCS Storage Driver	`spacecatninja/imager-x-gcs-storage-driver`
Kraken optimizer	Imager X Kraken Optimizer	`spacecatninja/imager-x-kraken-optimizer`
Tinify optimizer (previously "tinypng")	Imager X Tinify Optimizer	`spacecatninja/imager-x-tinify-optimizer`

If you used the Imgix transformer in Imager X 5, you need to install the plugin and migrate your settings over to the plugins config file. The settings has been renamed, refer to the plugin documentation for details.

Note that the Tinify optimizer was previously called "tinypng" in Imager X 5. When upgrading, replace any references to tinypng in your optimizer config with tinify.

Refer to the respective plugin's documentation for setup instructions.

Upgrading from Imager 4.0 to 5.0?

There should be no breaking changes going from 4.0 to 5.0.

Upgrading from Imager 3.0 to 4.0?

There should be no breaking changes going from 3.0 to 4.0. A couple of things that was marked as deprecated in 3.0 has been removed, so make sure you solve any deprecation errors in Craft 3.0 before upgrading to 4.0.

Upgrading from Imager 2.0 to 4.0?

The easiest approach will be to upgrade Imager 2.0 to Imager X 3.0 first (obviously before upgrading Craft itself), make sure you fix any deprecation errors, and then upgrade to 4.0.

Upgrading from Imager 2.0 to 3.0?

Before upgrading, make sure you uninstall Imager 2.0 first, since there are conflicting dependencies.

Imager X is a drop-in replacement for Imager 2.0. All you need to do is copy over your config settings from your imager.php file to imager-x.php, and you're good to go! Some things have been deprecated, so check your deprecation warnings and fix as needed.
