URL Encoder & Decoder

Encodes or decodes a URL component (encodeURIComponent) or a full URL while preserving its structure, analyzes a URL's parameters in an editable table, detects duplicate keys, and lets you build or normalize a query string. It never visits the URL or checks its reputation, and warns about dangerous schemes like javascript: or data: before presenting them as a link.

Frequently asked questions

Does this tool visit or check the URL?
No. It only encodes, decodes, and analyzes the URL's text; it never visits it, follows redirects, or checks its reputation.
What's the difference between encoding a component and a full URL?
encodeURIComponent also encodes characters like "/", ":", or "&", which would break a full URL; full-URL encoding preserves those structural characters.
