# URL encode

## Description

This operation converts a URL into an encoded string. URL encoding is used to encode special characters in URLs to ensure safe and proper transmission over the internet.

***

## Data types

These are the input/output expected data types for this operation:

### Input data

`String` - URLs to be encoded

### Output data

`String` - Resulting encoded strings of your URLs.

***

## Example

Suppose you want to **encode a series of URLs** in your input data. To do it:

1. In your Pipeline, open the required [Action](/pipelines/actions.md) configuration and select the input **Field**.
2. In the **Operation** field, choose **URL encode**.
3. Give your **Output field** a name and click **Save**. Your URLs will be converted. 

For example the following URL-encoded string:

```
https://example.com/search?q=Hello World!
```

will be encoded like this:

```
https://example.com/search?q=Hello%20World!
```
