Detailed Guide & Usage
Base64 encodes binary data into ASCII text using 64 characters. It is widely used to embed images in HTML/CSS, encode API credentials, and transmit binary data through text-based protocols. Our tool encodes and decodes with full UTF-8 support, entirely in your browser.
How to Use:
- Paste text into the input field.
- Select Encode to turn plain text into Base64, or Decode for the reverse.
- Copy the generated output string.
