URL Inspector

Inspect absolute URL syntax and percent-encode components without fetching the destination.

Runs in your browser

Runs in this browser. Input is not sent to a utility provider.

Input limits

  • Up to 16,384 URL characters, measured as UTF-16 code units.
  • At most 256 ordered query entries.

Inspect absolute URL syntax

Parsing uses the browser URL implementation. It does not contact, open, or assess the destination.

Enter one absolute URL including its scheme. Limit: 16,384 UTF-16 code units.

Reconstructed URL (may contain credentials)

Percent-code one component
This encodes or decodes one component value, not a complete URL. Decoding does not treat a plus sign as a space.
Component input is limited to 16,384 UTF-16 code units. Use Encode component or Decode component explicitly.
Component result
Example tasks
  • Inspect an absolute URL's scheme, hostname, port, path, ordered query entries, and fragment.
  • Edit duplicate or blank query keys in memory and reconstruct normalized URL text.
  • Percent-encode or decode one path, query, or fragment component without transforming a whole URL.
What this tool does not prove
  • Successful syntax parsing does not prove safety, reachability, ownership, reputation, or business validity.
  • The page never fetches, resolves, previews, navigates to, or reputation-checks the supplied destination.
  • Embedded credentials are risky. Presence is reported without repeating a password outside the explicit reconstructed result.
  • The browser URL implementation may normalize hostnames, default ports, escapes, and Unicode domain names.
  • The ordered query editor is limited to 256 entries, and reconstructed URL text remains within the 16,384-code-unit URL bound.
  • Input, query edits, and results remain in current-page memory and are not saved or copied automatically.
