Base64 Encoder & Decoder

Convert text to Base64 or decode Base64 data when working with web development, APIs, and data representations.

What this utility does

The Base64 Encoder & Decoder converts supported text between its normal representation and Base64 encoding in the browser.

How to use

  1. Enter the text or Base64 value.
  2. Choose the encoding or decoding operation.
  3. Copy the resulting value for use in your development workflow.

Practical notes

  • Base64 is an encoding format, not encryption.
  • Encoded output can be larger than the original binary representation and should not be treated as a security boundary.
