Encoding workspace

Transform text with Base64 and URL-safe percent encoding. Everything runs locally; copy results when you are done.

Text input

Base64

Encode or decode using UTF-8 bytes so Unicode text round-trips correctly. Processing is local in your browser.

Decoding arbitrary binary to UTF-8 may fail if the payload is not text.

Uses encodeURIComponent and decodeURIComponent for query strings and path segments. Runs entirely on the client.

For full URLs, encode only the pieces that need escaping—encoding an entire URL can break the scheme.
