What is Base64 and Why Use It?

Base64 is a way to represent binary data, like images, in a text-based format. Instead of linking to an image file, you can embed the entire image directly into your HTML, CSS, or JavaScript code.

This can be useful for small, critical images like icons or logos. It reduces the number of HTTP requests a browser has to make, which can slightly improve page load speed. Our tool provides a quick and easy way to convert images to Base64 strings and vice-versa.
