URL Encoder & Decoder
Encode and decode URLs and query strings with proper percent-encoding. Spaces, ampersands, Bengali text, emoji, and symbols all have special meaning inside a URL — and when they appear in a query parameter they must be encoded or the link breaks. This tool converts readable text into a valid URL-safe string, and back again, handling UTF-8 characters correctly. Choose full encoding (encodeURIComponent, for parameters) or smart URL-encoding (encodeURI, which preserves structure like / and ?). Built for developers and marketers debugging tracking links, UTM parameters and API calls — all locally in your browser.
