About This Tool
The Base64 Encoder / Decoder tool allows you to easily convert text or data into Base64 format and decode Base64 back to readable text. Base64 is a method of encoding binary data into plain text so it can be safely transmitted over systems that handle text only.
It is commonly used in web development, APIs, email attachments, image embedding (data URLs), and authentication tokens. Base64 does not encrypt data — it only encodes it for safe transfer.
This tool is useful for developers, system administrators, and anyone working with APIs, JSON data, or encoded content.
How to Use
- Enter your text or paste Base64 data into the input box.
- Choose whether you want to Encode or Decode.
- Click the convert button.
- Copy the output result instantly.
The process is fast and works directly in your browser.
