Base64 is an encoding scheme that represents data using 64 printable ASCII characters (A–Z, a–z, 0–9, + and /). It's used to safely carry data — like an image or a token — through systems that only handle text, such as email, JSON or URLs.
Base64 is not encryption: anyone can decode it. It only makes binary data text-safe.
You can encode or decode Base64 instantly in your browser.
