Broken Link Checker

Test links from a public webpage and find missing destinations, redirects and checks that need review.

Free No sign-up Instant results

Reads one HTML page up to 512 KiB, then checks up to 20 unique links. It does not crawl the whole website or run JavaScript.

404 and 410 mean missing destinations. Access blocks, rate limits, TLS failures and timeouts need review; they are not automatically broken links.

URLs are sent to the GigaTools server and the destination websites. Do not submit private or signed links. Only public IPv4 destinations on standard HTTP and HTTPS ports are supported.

How it works

How to use Broken Link Checker

Enter a page with links

Paste a public webpage URL. The checker reads links from its HTML source, not from a JavaScript-rendered browser page.

Review the tested links

Up to 20 unique links are tested with HEAD requests and limited redirect following. Read missing destinations separately from access blocks and failed checks.

Fix the source link

Use the link text and destination to find the link on your page. Confirm the issue in a browser before changing or removing it.

FAQ

Good to know

How do I use Broken Link Checker?

1. Enter a page with links: Paste a public webpage URL. The checker reads links from its HTML source, not from a JavaScript-rendered browser page. 2. Review the tested links: Up to 20 unique links are tested with HEAD requests and limited redirect following. Read missing destinations separately from access blocks and failed checks. 3. Fix the source link: Use the link text and destination to find the link on your page. Confirm the issue in a browser before changing or removing it.

Does it scan my entire website?

No. It reads one submitted page and tests the first 20 unique HTTP or HTTPS links it finds. A time limit can leave links unchecked. The report states how many links were discovered.

Is every failed check a broken link?

No. A 404 or 410 response indicates a missing destination. A 403, 429, timeout or TLS failure needs investigation. Some sites reject HEAD requests or automated clients.
