How it works

  1. Paste URL — full URL including query and hash.
  2. Components — each part shown separately.
  3. Query params — key-value pairs decoded from the query string.

Percent-encoded characters in path and query are decoded for readability. Invalid URLs show a clear error instead of silent failure.

Build URLs

The How to parse and decode URL components is free, runs locally, and never sends your data to a server. More developer tools at maratool.com.
