Base64 Encode

Convert Unicode text to UTF-8 bytes and Base64-encode those bytes directly in the browser.

Input stays in this browser.
How it works

Immediate local processing.

  1. 1. Enter your input. Paste text, a value or the data this utility expects.
  2. 2. Adjust the relevant options. The result updates locally as your input changes.
  3. 3. Copy the result. No remote conversion roundtrip is required.
Common uses

Useful when you need to…

  • Clean or transform base64 encode input
  • Work with copied data without a remote utility service
  • Create a result you can copy immediately
