Why Use Base64 Encoding?
Base64 encoding converts binary data into ASCII text so that it can be safely transmitted through systems that only support text-based formats. This is especially useful when sending data through email, JSON APIs, or web forms.
- Safely transmit binary data over text-based protocols
- Embed images or files in HTML, CSS, or JSON
- Store encoded data in configuration files
- Protect data formatting during transmission
