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
