## Solution

To remove a password from a PDF using [PdfFormatProvider](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/pdfformatprovider), import the password-protected document with [PdfImportSettings](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#import-settings), then export it with [PdfExportSettings](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#export-settings) without encryption.

1. Use the [ImportSettings](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#import-settings) property of [PdfFormatProvider](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/pdfformatprovider) to supply the password for the protected PDF.
2. Handle the [UserPasswordNeeded](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#import-settings) or [OwnerPasswordNeeded](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#import-settings) event to provide the password when required.
3. Import the document into a [RadFixedDocument](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/model/radfixeddocument).
4. When exporting, keep [ExportSettings](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#export-settings) configured so that [IsEncrypted](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#export-settings) is `false` and leave [UserPassword](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#export-settings) and [OwnerPassword](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfformatprovider/settings#export-settings) unset.

The following example demonstrates this process:

```csharp
using Telerik.Windows.Documents.Fixed.FormatProviders.Pdf;
using Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Import;
using Telerik.Windows.Documents.Fixed.Model;
using System.IO;

// Create PdfFormatProvider and configure import settings
PdfFormatProvider provider = new PdfFormatProvider();
PdfImportSettings settings = new PdfImportSettings();
bool isPasswordProtected = false;

// Handle UserPasswordNeeded event
settings.UserPasswordNeeded += (s, a) =>
{
    isPasswordProtected = true;
    a.Password = "YourPasswordHere"; // Supply the user password
};

// Handle OwnerPasswordNeeded event
settings.OwnerPasswordNeeded += (s, a) =>
{
    isPasswordProtected = true;
    a.Password = "OwnerPasswordHere"; // Supply the owner password
};

provider.ImportSettings = settings;

// Import the password-protected PDF
RadFixedDocument document;
using (Stream stream = File.OpenRead("input.pdf"))
{
    document = provider.Import(stream);
    // Document is loaded if the password is correct
}

// Configure export settings
provider.ExportSettings.IsEncrypted = false; // Ensure no encryption

// Export the document to a new PDF file
string pdfOutputPath = "output.pdf";
File.Delete(pdfOutputPath);
using (Stream output = File.OpenWrite(pdfOutputPath))
{
    provider.Export(document, output);
}
```
