How the Base64 Encoder Works
The SimpleTaskTools Base64 Encoder/Decoder is a free online tool for converting text to Base64 and vice versa. Base64 encoding is commonly used for encoding binary data in text formats, embedding images in CSS/HTML, and transmitting data through text-only channels.
Encode Text to Base64
Convert any text, including Unicode characters and special symbols, into Base64 format. This is useful for embedding data in URLs, storing binary data in JSON, or preparing text for transmission through systems that only support ASCII.
Decode Base64 to Text
Convert Base64-encoded strings back to their original text form. This is helpful for reading encoded data from APIs, decoding embedded content, or debugging data transmission issues.
Unicode Support
Our encoder fully supports Unicode characters, including emojis and characters from all languages. The tool handles UTF-8 encoding properly to ensure your text is accurately converted.
Privacy First
The conversion runs locally and does not send the entered value to a SimpleTaskTools endpoint. Base64 is reversible and should never be treated as encryption; browser extensions and clipboard history are outside the tool’s control.
