About Base64 Encode/Decode
Base64 is a way of encoding binary data (like an image) as plain text, which is commonly needed when embedding data directly into code, emails, or data URLs where only text is allowed. This tool encodes text or data into Base64, and decodes Base64 back into its original form.
Decoding works on any valid Base64-encoded input — paste the encoded text and get the original content back instantly.
