About URL Encoder/Decoder

URLs can only contain certain safe ASCII characters. Special characters like spaces, ampersands, and Unicode letters must be percent-encoded to be safely included in a URL. For example, a space becomes %20.

This tool uses the standard encodeURIComponent function to encode all special characters except unreserved ones (A–Z, a–z, 0–9, -, _, ., ~). Use it to build query parameters, API request URLs, or decode URLs from logs and analytics reports.
