# Split PDFs on iOS

Nutrient’s [`Processor`](https://www.nutrient.io/api/ios/documentation/pspdfkit/processor) API enables you to split a PDF document into multiple documents.

[`Processor`](https://www.nutrient.io/api/ios/documentation/pspdfkit/processor) can extract ranges of pages from one document and put them into another document. If you run this operation multiple times with different page indexes, you can effectively split a PDF into as many documents as you require.

In most cases, you’ll want to use [`Processor`](https://www.nutrient.io/api/ios/documentation/pspdfkit/processor) to create PDF documents on disk based on a current [`Document`](https://www.nutrient.io/api/ios/documentation/pspdfkit/document). This example code will split a single PDF document into two at the provided page index:

```swift

let document =...

// Split on the fifth page.
let splitIndex = 5
precondition(splitIndex > 0 && splitIndex < document.pageCount)

// Save the output in the app documents directory.
let documentsDirectory = FileManager.default.urls(for:.documentDirectory, in:.userDomainMask).first!
let splitPath = documentsDirectory.appendingPathComponent("Split")

let ranges = [IndexSet(integersIn: 0...splitIndex - 1),
              IndexSet(integersIn: splitIndex...Int(document.pageCount - 1))]

for (index, indexSet) in ranges.enumerated() {
    let configuration = Processor.Configuration(document: document)!
    // Specify the page range to keep after processing.
    configuration.includeOnlyIndexes(indexSet)

    let processor = Processor(configuration: configuration, securityOptions: nil)
    // Save to a new file on disk. Use a unique name.
    let output = URL(string: "\(splitPath)_\(index)_\(NSUUID().uuidString).pdf")!
    try processor.write(toFileURL: output)
}

```

Similar functionality is also available via the [Document Editor](https://www.nutrient.io/guides/ios/features/document-editor.md). See the [`PDFDocumentEditor.exportPages(_,to:, withCompletionBlock:)`](https://www.nutrient.io/api/ios/documentation/pspdfkit/pdfdocumenteditor/exportpages(_:topath:withcompletionblock:)) API documentation for more information.
