Privacy
This tool runs entirely in your browser. Your data is processed locally and never uploaded to a server.
How to use this tool
- Paste the URL string you want to check into the input field.
- Run the validator to let the browser's native URL parser inspect it.
- Read the result to see whether the URL is valid or invalid.
- If it is valid, review the parsed parts such as scheme, host, and path.
Step by step, what happens
- The tool takes the raw text you enter and sends it to the browser's built-in URL parser.
- It checks whether the string is well-formed as a URL, including the scheme, host, and overall structure.
- If the parser accepts it, the tool displays the URL as a valid result and shows its parts.
- If the parser rejects it, the tool marks it invalid so you can fix the format and try again.
Worked example
Here is a simple example using a full HTTPS URL with a path.
Input: https://example.com/docs
- The tool parses the string as a URL using the browser's native URL handling.
- It recognizes the scheme as https, the host as example.com, and the path as /docs.
- Because the string is well-formed, the tool reports it as valid.
Output: Valid URL
scheme: https
host: example.com
path: /docs
Tips and common mistakes
- Include a scheme like https:// if you want the URL to be treated as a full absolute URL.
- Watch for missing hosts, extra spaces, and broken punctuation, because those often make a URL invalid.
- A URL can be valid even if it points to a domain that does not exist, because this tool checks structure, not whether the site is reachable.
- If you are testing a relative path like /about, this tool is not the right check because it validates well-formed URLs, not relative references.
Frequently asked questions
What makes a URL valid here?
It must be an absolute URL with a scheme (like https://) that the browser can parse.
Are relative paths valid?
No, relative URLs like /page need a base; this checks absolute URLs.
Does it visit the URL?
No, it only checks the format, nothing is requested.
