Decode and encode addresses

This URL Decoder site handles percent-encoding for links, queries, and redirects. Developers verify UTM tags, OAuth callbacks, and Cyrillic slugs without one-off scripts.

Parse queries and percent-encoding

Decoding reveals what reached your server after proxies and CDNs—useful for mysterious 404 links.

Long redirect_uri chains and nested parameters are supported.

Prepare text for safe links

Encoding escapes spaces, Unicode, and reserved characters per application/x-www-form-urlencoded rules.

Copy the result into href, Swagger, or email—most clients accept it as-is.
