# Automatically process multiple file types

Our Robots only start their work when their input file has a file type that they can handle. This allows you to do several different things with the same Assembly Instructions. For more advanced workflows you can resort to[🤖/file/filter](/docs/robots/file-filter.md), but for simple use cases this may not be needed.

In the demo below, notice how the Steps `image_thumbed`, `video_thumbed` and`ipad_encoded` all have a value of `:original` for their `use` parameter. Each Robot only processes the files it can handle, which means that [🤖/image/resize](/docs/robots/image-resize.md)for example gracefully ignores any videos that your user may upload.

Step 1

### Handle uploads

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

```
":original": {
  "robot": "/upload/handle"
}
```

🤖 [/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

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

Step 3

### Extract thumbnails from videos

We offer a variety of video encoding features like optimizing for different devices, merging, injecting ads, changing audio tracks, or adding company logos. [Learn more ›](/services/video-encoding.md)

## 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/docs/guides/uppy-transloadit/) 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.
