Build and inspect encoded URL query parameters.
Parse a query or add a row.

Use [key, null] for a key without an equals sign and [key, ""] for an empty value. Duplicate pairs and order are retained.
Parse a query or add a row.
Paste a query and parse it into ordered rows, or build from scratch. Excluded rows remain editable but do not appear in generated output. The tool never opens or fetches the generated URL.
Edit ordered query pairs bidirectionally, preserve duplicate and empty entries, choose percent or plus space encoding, and generate a copyable URL without navigation.
