What does URL encoding do?

URL encoding replaces characters that are unsafe or meaningful in URLs with percent-encoded byte values, such as a space becoming %20.

What is the difference between encodeURI and encodeURIComponent?

encodeURI preserves the structural characters of a full URL. encodeURIComponent also escapes separators such as question mark, ampersand, equals, slash, and colon, making it suitable for a query value or path segment.

Does URL decoding support Unicode?

Yes. Percent-encoded UTF-8 sequences are decoded back into Unicode text by the browser URI functions.

Encode and Decode URLs Online

Convert text into percent-encoded URI data or decode an encoded value back into readable text. Component mode is designed for query values, form values, and path segments. Full URL mode keeps URL separators intact while encoding spaces, Unicode text, and other unsafe characters.

When to Use Each Mode

URI Component

Use for a single query parameter value, redirect target, search term, filename, or path segment.

Full URL

Use when the input already contains a complete URL and its protocol, path, query separators, and fragment must remain readable.

API Debugging

Decode request parameters from logs or safely encode values before building API and webhook URLs.

International Text

Encode spaces, emoji, accents, and non-Latin characters as UTF-8 percent sequences.
