# About Box Doc Split

<div className="article_labels_list" style={{display: 'none'}} dangerouslySetInnerHTML={{__html: "End User , Box Doc Gen , Overview , Article , Product Utilization , New"}} />

Box Doc Split breaks a multi-page PDF stored in Box into smaller sub-documents and saves the results to a Box folder.

Use Box Doc Split when you need to:

* Break a multi-page PDF into page ranges you define yourself with a [manual split](/en/box-doc-gen/doc-split/manual-split)
* Have Box group pages based on natural language instructions with a [smart split](/en/box-doc-gen/doc-split/smart-split)

<Note>
  Box Doc Split is available through the Box API only. To split documents, work with your development team or see [Box Doc Split](https://developer.box.com/guides/docgen/doc-split/) in the Box Developer Documentation.
</Note>

Before you split documents, an admin must enable the required settings. See [Enabling Box Doc Split](/en/box-doc-gen/doc-split/enabling-box-doc-split).

## Example use cases

Box Doc Split suits any process where a single PDF arrives as a bundle that has to be separated before anyone can act on it.

| Team       | Example                                                 |
| ---------- | ------------------------------------------------------- |
| Sales      | Split multi-deal packets into individual quotes         |
| Legal      | Isolate signatures and ID proofs from contract packages |
| Finance    | Extract invoices from a multi-invoice PDF               |
| Operations | Split scan batches at QR code separators                |
| HR         | Separate onboarding packet sections                     |

## How it works

Splitting a document follows the same sequence regardless of the split type you choose:

1. Identify the source PDF in Box.
2. Choose a destination folder. You need write access to this folder.
3. Select the manual or smart split type.
4. Run Box Doc Split through the Box API.
5. Review the split documents in the destination folder.

## Split types

Box Doc Split supports 2 split types. The type you choose determines what you supply along with the source PDF.

| Split type                                       | Best for                                 | You provide                                   |
| ------------------------------------------------ | ---------------------------------------- | --------------------------------------------- |
| [Manual](/en/box-doc-gen/doc-split/manual-split) | Known page ranges                        | A start and end page for each output document |
| [Smart](/en/box-doc-gen/doc-split/smart-split)   | Content-based or marker-based boundaries | A natural language prompt                     |

<Tip>
  Use a manual split when you already know the page numbers, because the results are the same every time. Use a smart split when the boundaries are easier to describe than to calculate.

A smart split consumes AI Units. For details on how Box meters AI usage, see [Understanding AI Units in Box](/en/box-ai/understanding-ai-units-in-box).
