# Search and Replace With Image
> Enhance your Zapier workflow by integrating this step to search for text inside a PDF and replace it with an image. This feature supports the use of regular expressions for advanced text search capabilities.
## Input
| Name | Description | Required |
| ------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- |
| **Source PDF URL** | Provide the URL to the source PDF document, or a `filetoken://` link from [PDF.co Built-In Files Storage](https://app.pdf.co/files). If you use another cloud service such as **Google Drive** or **Dropbox** ensure the link is publicly accessible. | Yes |
| **Text to Locate** | Specify the text you want to find within the PDF. | Yes |
| **Replacement Image URL** | Provide the URL of the image to be used as a replacement for the located text. | Yes |
| **Enable Regular Expressions** | Activate this option to use regular expressions in your search, such as `[0-9]{3}-[0-9]{2}-[0-9]{4}` for finding SSN patterns. | No |
| **Case-Sensitive Search** | Toggle this for a case-sensitive search. | No |
| **Target Pages** | Indicate the pages to be searched. Enter a comma-separated list of page numbers or ranges. Note: The first page is numbered `0`. For example: `0,1-5,7-`. | 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.
