How to Use the Encoder / Decoder

Use the URL tab to encode special characters for URLs or decode percent-encoded strings back to readable text. Use the Base64 tab to encode text to Base64 format or decode Base64 strings. The swap button lets you quickly use the output as new input.

All encoding and decoding happens locally in your browser. Your data is never sent to any server.
