Use the Base64 Encode / Decode tool to convert text into Base64 or restore encoded strings for APIs, emails, JSON payloads, and debugging tasks, locally.
The Base64 Encode/Decode tool allows you to quickly convert text into Base64 format or restore Base64 strings back into readable text. Base64 encoding is widely used for safely transmitting binary data over systems that handle only text, such as JSON, email, and various web protocols. Developers often rely on Base64 for embedding small images, storing compact data, or passing information through APIs. This tool performs all encoding and decoding instantly on your device, meaning nothing is stored or sent to a server. It supports full Unicode and handles special characters without corruption, making it reliable for testing, debugging, and data preparation. Whether you're learning about encoding systems, integrating web features, or just experimenting with encoded text, this tool provides a simple and secure way to work with Base64.
