Frequently Asked Questions

Find Quick Answers

What types of URLs can I check?

You can check any valid HTTP or HTTPS URL, including web pages, images, APIs, and downloadable files. The tool supports standard web protocols.

How many URLs can I check at once?

The tool can handle hundreds of URLs in a single batch, but performance may vary based on your network speed and server responses. For very large lists, consider breaking them into smaller chunks.

Does the tool store or log my URLs?

No, all processing is done client-side in your browser, and no data is sent to external servers (unless you enable backend features). Your URLs remain private and are not stored.

What do the different HTTP status codes mean?

Status codes indicate the result of the HTTP request: 200 (OK), 301/302 (redirects), 404 (not found), 500 (server error), etc. The tool provides a brief explanation for each code in the results.
