Why Use Base64 Encoding?

Base64 encoding allows you to embed binary data (like images or fonts) directly into HTML, CSS, or JSON files. This reduces the number of HTTP requests your website makes, potentially speeding up load times for small assets. It is also essential for transmitting binary data over reliable transport layers that are text-based, like email.

Note: Since this tool runs entirely in your browser, large files may take a moment to process depending on your device's speed.
