Image to Base64
This action helps you encode an image file on your computer into a long text string (Base64 string).
Effect: Extremely useful when you need to send images via network commands like HTTP Request. For example, you want to send an image to AI services to decode a captcha, or upload an image to a server without transmitting the file in the usual way.
Image Path: The absolute path to the image file on your computer that needs to be converted (For example: D:\GPM_Data\captcha.png).
Output variable: The name of the variable that will store the Base64 string after successful encoding.
Practical example: Converting a Captcha image to send to the automatic solving system via API
When you navigate to a website and encounter an image-based Captcha. You have used the Screenshot action to capture the area containing the Captcha code and saved it as an image file at D:\GPM_Data\captcha.png. Now, you want to send this image to a third-party API (like 2Captcha, Anti-Captcha) for them to solve it for you. Since their API requires the image data to be in the form of a Base64 text string, you will configure it as follows:
Step 1: Call the Image to Base64 action.
Image Path: Enter D:\GPM_Data\captcha.png.
Output variable: Name the variable base64String.
Step 2: Call the HTTP Request action (Method POST) to send the data to the captcha solving Server. In the Data (Body) section, you pass the variable $base64String into the JSON structure according to their API documentation.
Result: The image file captcha.png will be broken down into a long string of code like data:image/png;base64,iVBORw0KGgoAAAANSU... stored in the variable $base64String. The subsequent HTTP Request command simply sends this string neatly, helping the automated script easily bypass captcha security layers.
