What Is Image to Base64?
Base64 is an encoding technique that converts binary data (like images) into a text string. This allows images to be:
- Embedded directly into HTML or CSS
- Sent safely in JSON or API requests
- Stored in text-based formats without corruption
Example of a Base64 image:
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA...
