How to use the URL & Base64 Encoder

Handle common developer encodings in one place. The result follows “Text ↔ UTF-8 bytes ↔ encoded string” and is designed for situations such as encode a query parameter. Inputs are handled immediately in your browser with no account required.

How it works

Text ↔ UTF-8 bytes ↔ encoded string

Most processing stays in your browser instead of sending inputs to our server. Verify important financial or contractual decisions against an authoritative source.

Useful examples

  • Encode a query parameter
  • Convert Unicode to Base64
  • Inspect encoded output

Frequently asked questions

Does Unicode Base64 work?
