About Base64 Encoder & Decoder
Base64 Encoder & Decoder combines two common developer tasks on one browser-based page. Paste plain text and encode it into Base64, or paste an encoded string and decode it back into readable text. The decoder checks invalid Base64 input and shows a clear error instead of producing confusing output. This is useful when working with API samples, authorization examples, headers, configuration values, small payloads, data snippets, documentation and debugging notes. Base64 is encoding rather than encryption, so the tool is best used for representation and testing rather than protecting secrets. All processing happens locally in your browser with JavaScript, and Toolexa does not upload or permanently store the text you enter. The result can be copied or downloaded as a text file, and the Clear button resets the page for another value. The interface follows the same Toolexa developer-tool layout with responsive editors, status messages, FAQs, related tools, breadcrumbs, schema markup and shareable page metadata.
