What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that converts binary data into a readable ASCII string format. It is commonly used to encode text, files, or data streams for safe transmission over media that are designed to handle textual data, such as emails, JSON, and URLs. Base64 ensures that the data remains intact without corruption during transport.

Why Use a Base64 Encoder / Decoder?

A Base64 Encoder / Decoder is essential for developers, testers, and security professionals who work with APIs, web applications, or file transfer. By encoding text into Base64, you can safely transmit data across platforms. Decoding Base64 back to readable text is crucial when analyzing or debugging data.
