# PDF Security
> Integrate this step into your Zapier workflow to add or remove password protection and security features to or from a PDF file.
**Modifying Restriction Settings**: To modify assembly or extraction settings that control PDF restrictions (such as `allowPrintDocument`, `allowFillForms`, `allowModifyDocument`, `allowAssemblyDocument`, and related permission settings), you **must** use the `ownerPassword` in your request. The `userPassword` alone cannot modify these permission settings. Attempting to change these restrictions with only a `userPassword` will result in an error: `"This file is password-protected. Please ensure you've entered the correct password…"`. This requirement applies only when making changes to those restrictions.
## Input
| Name | Description | Required |
| -------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------- |
| **Source PDF URL** | Provide the URL of the source PDF document or a `filetoken://` link from [PDF.co Built-In Files Storage](https://app.pdf.co/files). For cloud services like Google Drive or Dropbox, ensure the link is publicly accessible. | Yes |
| **Operation Mode** | Select to either add or remove security features from the PDF file. | Yes |
| **Owner Password** | Set the owner password for applying restrictions and encryption. You can also utilize [user-controlled data encryption](/knowledgebase/user-controlled-encryption). | Fill at least one for Remove Security |
| **User Password** | Optionally set a user password required to view or print the document. | Fill at least one for Remove Security |
| **Encryption Algorithm** | Select the encryption algorithm for built-in PDF encryption. AES-128 or higher is recommended. | No |
| **Allow Printing** | Determine if the PDF can be printed. Applies when the user password is entered; bypassed with the owner password. | No |
| **Define Printing Quality** | Specify the allowed printing quality. Applies with `userPassword`; bypassed with `ownerPassword`. | No |
| **Enable Document Assembly** | Decide if document assembly is allowed. Effective with `userPassword`; bypassed with `ownerPassword`. | No |
| **Enable Content Copying** | Decide if content copying is allowed. Effective with `userPassword`; bypassed with `ownerPassword`. | No |
| **Enable Content Copying for Accessibility** | Decide if content extraction for accessibility is allowed. Effective with `userPassword`; bypassed with `ownerPassword`. | No |
| **Enable Document Modification** | Decide if document modification is allowed. Effective with `userPassword`; bypassed with `ownerPassword`. | No |
| **Enable Form Field Filling** | Decide if filling form fields is allowed. Effective with `userPassword`; bypassed with `ownerPassword`. | No |
| **Enable Commenting** | Decide if interacting with text annotations and forms is allowed. Effective with `userPassword`; bypassed with `ownerPassword`. | No |
| **Specify Name** | Provide a base file name for the processed PDF files. | No |
| **Custom Profiles** | A `JSON` string which adds options for the conversion process. See [Custom Profiles](#custom-profiles) for more. | No |
### Source PDF URL & Google
When using **Google Drive**, it’s typically recommended to choose the **File** option. For more advanced file integration techniques, see [Integrating File Sources with pdf.co](/integrations/zapier/input-file-sources).
## Output
| Name | Description |
| --------------------- | ---------------------------------------------------------------------------------------- |
| `url` | The temporary **URL** on the **PDF.co** file server. |
| `outputLinkValidTill` | A timestamp which indicates how long the `url` will be available for. |
| `error` | Details of any errors (if any). |
| `status` | The [response status](/api-reference/introduction) code. If all good this will be `200`. |
| `name` | The name of the file. |
| `jobId` | The unique identifier for the job. |
| `credits` | The credits spent on the process. |
| `remainingCredits` | The credits left on your account. |
| `duration` | The time it took for the process. |
## Custom profiles
Use Custom [Profiles](/api-reference/profiles) to enhance your workflow with additional processing options. Enter `JSON` configuration to customize OCR settings, output format, text extraction methods, and more.
### Sample JSON
```json theme={null}
{ "ImageOptimizationFormat": "JPEG", "JPEGQuality": 25, "ResampleImages": true, "ResamplingResolution": 120, "GrayscaleImages": true }
```
You can use any regular API parameter from the [API Reference](/api-reference) within Zapier using the `std_params` feature in profiles. The `std_params` enables the definition of regular API parameters in a JSON format, See [Standard Parameters](/api-reference/profiles#standard-parameters) for detailed documentation and examples.
