URL Encoder / Decoder

Quickly encode data for safe URL transmission or decode percent-encoded strings.

What is a URL Encoder & Decoder?

A URL Encoder converts text with special characters into percent-encoded URL-safe format (e.g. space → %20), and a Decoder converts encoded URLs back to readable text.

Why Use This Tool?

URLs can only contain certain ASCII characters. Special characters must be encoded to be valid and transmit correctly. See also the Base64 Encoder for broader encoding needs.
