It's widely used in web development to safely transmit data through mediums that only support text — like embedding images in HTML, passing data in URLs, or encoding credentials in HTTP Authorization headers. Our Base64 encoder and decoder works instantly in your browser — just paste your text or Base64 string and convert in one click.

How to use:

• 1. Paste your plain text into the input box to encode it
• 2. Or paste a Base64 string to decode it back to plain text
• 3. Click Encode or Decode
• 4. Copy the output with one click
