# Save and upload PDFs on iOS devices

Nutrient [automatically saves](https://www.nutrient.io/guides/ios/annotations/annotation-and-bookmark-saving-triggers.md) a modified file-based document to your device’s local storage. You can also [customize the autosaving behavior](https://www.nutrient.io/guides/ios/annotations/annotation-and-bookmark-saving-triggers.md#customize-autosaving) or [manually save](https://www.nutrient.io/guides/ios/annotations/annotation-and-bookmark-saving-triggers.md#manual-saving) the changes.

After the document is saved, you can upload the PDF file to your remote server using [`URLSession`](https://developer.apple.com/documentation/foundation/urlsession)’s [`uploadTask(with:fromFile:)`](https://developer.apple.com/documentation/foundation/urlsession/1411550-uploadtask) method. The example below shows how to manually save a PDF and upload it to your remote server:

```swift

let fileURL = Bundle.main.url(forResource: "Document", withExtension: "pdf")!
let document = Document(url: fileURL)

// Modify the document.
//...

// Manually save the document.
try? document.save()

// Upload the PDF file to your remote server using `URLSession`:
let session = URLSession.shared
let serverURL = URL(string: "http://127.0.0.1:12345")!
var request = URLRequest(url: serverURL)
request.httpMethod = "POST"
let task = session.uploadTask(with: request, fromFile: document.fileURL!)
task.resume()

```
