Broken Link Checker

This broken link checker analyzes your URLs to identify dead ends, timeouts, or unexpected redirects. Paste a single URL into the input field, enter a list of links in the bulk editor, or upload a file containing URLs to check everything at once. Each link is tested with an HTTP HEAD request, providing real-time results with color-coded status badges for OK, Broken, Redirect, Timeout, or Error. Response times and HTTP status codes appear next to every link so you can prioritize your fixes. Once the scan finishes, you can download a complete CSV report for your records or to share with your team.

Dead links hurt user experience and can damage search engine rankings. Regular scanning catches problems before visitors do, whether the issue is a deleted page, a misconfigured redirect, or a server that stopped responding. Because this tool runs entirely in your browser, your URLs and results stay private and never travel to an external server.

Single URL Check

Validate one link instantly with HTTP status code, response time, and redirect detection.

Bulk Link Check

Paste or upload hundreds of URLs and process them in parallel batches of five for fast results.

Sitemap Checker

Verify that your sitemap URL is reachable and responding correctly to search engine crawlers.

File Upload

Drop a TXT, CSV, HTML, or XML file to extract and check all URLs found inside automatically.

CSV Report Export

Download your scan results as a CSV file with URL, status, status code, response time, and error details.

How to Use the Online Broken Link Checker

Start by selecting a check mode from the toolbar: Single URL, Bulk Check, or Sitemap. For a single link, type or paste the URL into the input field and click Check Link. For multiple links, switch to Bulk Check and enter one URL per line, or click Upload File to import a text file, CSV, or HTML document. The checker extracts every valid URL from uploaded files automatically, so there is no need to clean up the data first.

Understanding Status Results

Your scan results use clear badges to indicate the health of each link. A green OK badge signifies a successful server response (HTTP 200-299), while Redirect shows the URL has moved (HTTP 300-399). Broken links return client or server errors (HTTP 400-599), and Timeout flags servers that failed to respond within 15 seconds. For network failures or DNS problems, the tool displays an Error status.

Uploading Files with URLs

Click the Upload button or drag a file directly onto the input panel. Supported formats include TXT, CSV, XML, and HTML files. The tool scans the entire file content for valid URLs and populates the bulk input area with every link it finds. This makes it easy to check exported link lists, sitemap files, or bookmarks collections without manual copy-pasting.

Free Broken Link Checker for Website Maintenance

Maintaining a healthy link profile is essential for any website. Search engines penalize pages with excessive dead links, and visitors who click a broken link are likely to leave your site immediately. Running periodic scans with this tool helps you stay ahead of link rot, catching broken URLs from deleted pages, expired domains, or changed URL structures before they accumulate.

Batch Processing for Large Link Lists

Your scan processes five links simultaneously, making it practical to check hundreds of URLs in a single session. A live progress bar tracks your completion, and you can stop the scan at any point without losing your data. This approach balances speed with efficiency, keeping your browser responsive during larger scans.

Exporting Results as CSV

After a scan completes, click the Download Report button in the toolbar to save all results as a CSV file. The report includes each URL, its status, HTTP status code, response time in milliseconds, and any error messages. Import the CSV into a spreadsheet application to sort, filter, and share findings with team members or clients.

Privacy and Security

Every HTTP request originates directly from your browser. No URLs, results, or uploaded files are transmitted to an external server. Your scan data exists only in browser memory and disappears the moment you close the tab. This client-side architecture makes the tool suitable for checking internal URLs, staging environments, or any links you prefer to keep confidential.

Browser-Based Link Validation

Link checking uses the browser Fetch API with HEAD requests for efficiency. Some servers restrict cross-origin requests, in which case the tool falls back to opaque responses and reports the link as reachable. A 15-second timeout prevents slow servers from blocking the entire scan. No browser extensions or installations are required.

No Account Required

Access every feature immediately without signing up or creating an account. There are no usage limits, no premium tiers, and no watermarks on exported reports. The tool is completely free for personal and professional use.
