The Base64 Encoder / Decoder tool allows you to convert text to and from Base64, a common encoding format used to safely transmit data over the web. Base64 does not encrypt or hide information; instead, it converts binary or text data into a set of readable characters that can be included in URLs, JSON, HTML, email, and configuration files without breaking formatting.

This tool is especially useful for developers and technical users who need to embed small images, tokens, or configuration data directly into code or markup. With just a few clicks, you can encode any text into Base64 or decode an existing Base64 string back into its original form. It supports long strings and works instantly without requiring any special setup.

All encoding and decoding happens in your browser using JavaScript, ensuring that your data is never uploaded or stored on any server. That makes this tool safe to use even with sensitive values, as long as you understand that Base64 is not encryption. It simply changes how the data is represented, not how secure it is.
