Free URL Encoder & Decoder

Encode and decode URLs, query parameters, and path segments instantly. Live preview, one-click swap, and full client-side processing.

Working with URLs often means dealing with special characters that break links, corrupt API requests, or cause encoding errors. This tool lets you encode any string into a URL-safe format or decode a percent-encoded string back to its original form — instantly, entirely in your browser. Toggle between full URI and component encoding modes, swap between encode and decode with one click, and preview results live as you type. Nothing is stored, transmitted, or tracked.
