How to use URL Validator

  1. Enter a URL (or switch to Bulk Mode for multiple URLs).
  2. Click Validate.
  3. Review the component breakdown and query parameters.

What is URL Validator?

Uses the browser built-in URL constructor to parse and validate URLs according to the WHATWG URL Standard. Single mode shows a detailed breakdown table. Bulk mode processes one URL per line and reports valid/invalid counts. Query parameters are extracted and displayed in a separate table so you can inspect keys and values at a glance.

FAQ

What URL schemes are supported?
The URL API supports http, https, ftp, ws, wss, and other standard schemes. Non-standard or malformed URLs will be flagged as invalid.
How does bulk mode work?
Toggle to Bulk Mode, paste one URL per line, and click Validate All. Each line is parsed independently and results are shown in a scrollable list.
Are URLs I validate sent anywhere?
No — all parsing happens client-side using the browser URL API. No network requests are made.
