URL Encoder / Decoder

URLs can only contain a limited set of characters. Everything else — spaces, ampersands, question marks, currency symbols, non-English letters — must be percent-encoded: a space becomes %20, & becomes %26, ₹ becomes %E2%82%B9. When you see a link full of % signs, this is what's happening; when a query parameter breaks because someone pasted raw text into it, this is what didn't happen.

This tool converts both directions, live as you type. Decoding turns unreadable analytics URLs, log entries and webhook payloads back into plain text (it also treats + as a space, the convention in form-encoded query strings). Encoding prepares text for safe use in a URL — and here the tool makes the distinction that trips people up: by default it encodes in component mode, escaping everything including / ? & =, which is correct when you're encoding a value going inside a query string. Tick "encoding a full URL" and it switches to preserving URL structure characters, correct when you're cleaning up a complete address.

Use the wrong mode and you either break your query parameters or double-escape your URL — the toggle plus its explanation prevent both. As always: entirely local, nothing uploaded.
