Base64 Encode / Decode
Convert text to Base64, or decode a Base64 string back to plain text.
What is Base64?
Base64 is a way of encoding binary or text data into an ASCII string using 64 printable characters (A–Z, a–z, 0–9, +, /). It's commonly used to embed images in CSS/HTML, encode data in URLs, attach files in emails, and pass binary data through systems that only support text — like JSON payloads or basic auth headers.
Is Base64 encryption?
No. Base64 is an encoding, not an encryption — anyone can decode it instantly with no key or password. Never use Base64 alone to protect sensitive data like passwords or tokens.
