# Crop a picture to fit the background dimensions of the Asus ZenBook UX305 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 1920x1080 so it matches the Asus ZenBook UX305's display exactly before optimizing the file to conserve storage. The Asus ZenBook UX305 display uses a 16:9 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.
