About this tool
Encode URL parameters or full URIs and decode percent escapes, with explicit handling of spaces, plus signs and Unicode.
How to use
Choose the context first: URL component for an individual value, full URI to retain address separators, or form value to encode spaces as plus signs. Edit either side to update the other.
Only form mode turns a plus sign into a space when decoding. Incomplete percent escapes and invalid UTF-8 bytes produce an error. Processing stays local, with a 2 MiB input limit.
