Broken links hurt user trust and SEO — search engines treat 404-heavy pages as low-quality and reduce their crawl budget. This checker fetches any URL server-side, extracts every <a href> link, and probes each one to report the HTTP status. Dead links, redirects and timeouts are flagged so you can fix or remove them before they cost you rankings. Useful for blog audits, post-migration checks, and quarterly site-health reviews.
Type or paste the target you want to inspect into the input field at the top of the page.
Click the check button — the tool queries live data sources and returns results in seconds.
Review each finding: status, score, and the reason behind every warning are listed line by line.
Follow the linked remediation guides to fix issues, or copy the report to share with your team.
When something in your stack misbehaves, half the battle is figuring out whether the problem is you, the network, or the other side. Broken Link Checker gives you a fast, opinionated readout so you can rule things in and out in seconds. Because the check runs on live infrastructure and reports raw results — not marketing-safe summaries — you can trust what you see and act on it. Toolzer's design philosophy is simple: privacy-first (no tracking, no accounts), performance-first (the page is interactive in under a second on a 3G connection), and honesty-first (no fake ratings, no dark patterns, no upsells). Broken Link Checker follows the same rules as every other utility on the site. You can bookmark this page, share the URL with a colleague, or pin it to your browser's toolbar — the experience will be identical every visit, and it will keep working even if you're on airplane Wi-Fi. Real people use this tool for real work — freelancers cleaning up client deliverables, sysadmins triaging tickets, students finishing assignments — and it is tuned for those workflows, not for demo videos.
Up to 60 unique links per page to keep the response time reasonable. Run it page by page for large sites.
Some servers block HEAD requests or non-browser user agents. The tool falls back to GET for 403/405, but a hardened WAF can still refuse. Open the link manually to confirm.
