How to use the Base64 Converter

Our Base64 Encoder and Decoder is a powerful utility designed for developers who need to embed images directly into HTML or CSS code. You can seamlessly convert any image file into a clean Base64 string, or reverse the process by turning a string back into a visible image.

Simply upload an image to generate your code, or paste a Base64 string to preview and download the graphic. Because this tool operates entirely offline and locally in your browser, it is fast, free, and guarantees your private files are never uploaded to the internet.
