About This Calculator

This URL decoder reverses percent-encoding so you can read the original text behind a URL. Sequences such as %20 (space), %26 (&), and %C3%A9 (é) are converted back to their real characters.

Because query strings sometimes use a + to mean a space, this decoder treats + as a space — the standard behavior for URL query parameters. Runs entirely in your browser with no uploads.

hello world & friends

Frequently Asked Questions

Why is there a + symbol in my decoded query?
In URL query strings, + is often a space. This decoder converts + to a space for you. If you meant a literal + (in a path, not query), the + would instead appear as %2B.
Can this decode emoji?
Yes. Emoji are stored as UTF-8 percent-encoded bytes (e.g. %F0%9F%98%80) and are decoded back to the original character.
