# Crop a picture to fit the background dimensions of the Google Pixel 8 Pro while keeping the file size low

Using a combination of our Robots we can create outstanding results, in this demo we will use two of them: [🤖/image/resize](/docs/robots/image-resize.md), allowing us to manipulate uploaded image and [🤖/image/optimize](/docs/robots/image-optimize.md), to reduce the size of our image while maintaining the same visual quality.

For this demo, we resize an uploaded wallpaper to 1344x2992 so it matches the Google Pixel 8 Pro's display exactly before optimizing the file to conserve storage. The Google Pixel 8 Pro display uses a 20:9 aspect ratio, which we respect during resizing.

For resizing we need to set a [resize strategy](/docs/topics/resize-strategies.md), for this post`fillcrop` will do the job. However for other creations using this Robot, another strategy may be more appropriate.

Step 1:

### ![Handle uploads](/_next/static/immutable/media/handling-uploads.36rsz9f-z39wy.svg)Handle uploads

We can handle uploads of your users directly.[Learn more ›](/services/handling-uploads.md)

🤖 [/upload/handle](/docs/robots/upload-handle.md)

This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically

Step 2:

### ![Convert, resize, or watermark images](/_next/static/immutable/media/image-processing.01ifhto-sjz1y.svg)Convert, resize, or watermark images

We can resize, crop, and (auto-)rotate images, or apply watermarks and other effects, and much more.[Learn more ›](/services/image-processing.md)

## Live Demo. See for yourself

Loading Uppy demo…

This live demo is powered by [Uppy⁠](https://uppy.io), our open source file uploader that you can also use without Transloadit, and [tus⁠](https://tus.io), our open protocol for resumable file uploads that is making uploading more reliable across the world.

## So many ways to integrate

Transloadit is a service for companies with developers. And there are many ways developers can put Transloadit to good use inside your company to automate media processing.

#### Bulk imports

Add one of our [import Robots](/services/file-importing.md) to acquire and transcode massive media libraries.

#### Handling uploads

We are *the* experts at reliably [handling uploads](/services/handling-uploads.md). We wrote the [protocol⁠](https://tus.io/) for it.

#### Front-end integration

We integrate with web browsers via our next-gen file uploader [Uppy⁠](https://uppy.io/) and SDKs for Android and iOS.

#### Back-end integration

Send us batch jobs in any server language using one of our [SDKs](/docs/sdks.md) or directly interfacing with our [REST API](/docs/api.md).

#### Pingbacks

Configure a [notify\_url](/services/content-delivery.md) to let your server receive transcoding results JSON in the `transloadit` POST field.

#### On-demand

Use our [Smart CDN](/services/file-importing.md) to adapt files on-demand and stream them directly to your users.
