Safely encode text strings or binary files into Base64 format for web transmission.
Encode plain text into Base64 format safely.
The Base64 Encoder takes any plain text string (including Unicode and emojis) and safely translates it into a Base64 string.
Hello WorldSGVsbG8gV29ybGQ=Base64 is an encoding scheme that represents binary data in an ASCII string format. It is commonly used to embed image data or send data over media that are designed to deal with textual data.
No. Base64 is merely an encoding scheme. It provides absolutely no security or encryption. Anyone can decode a Base64 string back into plain text.
