Encode text or files to Base64 format and decode Base64 strings. 100% client-side.
About Base64 Encoder/Decoder
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is widely used in web development to transmit assets, embed images directly inside HTML or CSS files (using Data URIs), and transfer data safely without character corruption over text-based networks.
Our Base64 Encoder/Decoder is a powerful utility for developers. You can encode strings or decode Base64 outputs with full support for UTF-8 character schemes. Additionally, you can upload images, SVGs, or fonts to generate Base64 Data URIs instantly. As with all VIPToolkit programs, files are read locally in memory using the HTML5 FileReader API—nothing is ever uploaded to a server, providing safe and secure developer workflows.
