Free Online URL Checker
Use the URL Checker to quickly see if your links are active, broken, or redirecting with tests that run right in your browser. You can paste your URLs one by one or upload a bulk list from a .txt, .csv, or .json file to get status codes, response times, and SSL details for every entry. In addition to link checking, you have access to five other useful utilities including format validation, component parsing, encoding, decoding, and redirect tracing. Since every operation runs locally on your machine, your data stays private and never touches our servers.
URL Checker
Test link reachability with HEAD requests and see status codes, response times, and SSL status for each URL.
URL Validator
Verify URL syntax and structure without making network requests for instant format checking.
URL Parser
Break any URL into protocol, hostname, port, path, query parameters, and hash fragment.
URL Encoder
Convert special characters to percent-encoded format for safe use in query strings and API calls.
URL Decoder
Reverse percent-encoding to reveal the original readable text from encoded URLs and parameters.
Redirect Checker
Follow HTTP redirects to discover the final destination of short links, affiliate URLs, and redirects.
Online URL Checker with Bulk File Upload
While checking a single link is fast, professional workflows often require auditing hundreds of URLs at a time. Simply drag and drop a .txt or .csv file with up to 500 entries, and the checker will process them while providing live status updates. Every result clearly shows a color-coded status icon, the HTTP response code, response time, and SSL connection details. When a URL redirects, the final destination is listed right beneath the original link. After your scan is complete, you can download a full CSV report to keep for your records or share with your team.
Drag-and-Drop File Import
Just drop your URL list onto the input panel to load everything at once. The checker supports .txt files, CSVs with URLs in any column, and JSON arrays. Duplicates are removed automatically and the list is capped at 500 URLs to ensure the tool remains fast and responsive.
CSV Export for Record Keeping
Clicking the download button creates a structured CSV file that includes the URL, status, response time, and redirect targets. You can open this file in any spreadsheet program to sort, filter, or merge it with your other link audit data.
URL Validation, Parsing, Encoding, and Decoding
Our built-in sub-tools handle the common URL tasks that developers and marketers face every day. Use the URL Validator to catch syntax errors and malformed links before they cause issues in production. The URL Parser breaks down every part of a link, from the protocol to query parameters, into an easy-to-read table. Our Encoder and Decoder tools manage percent-encoding, helping you convert special characters for query strings or turn encoded strings back into readable text.
Validate Without Network Requests
Because URL validation is based purely on syntax, you get results instantly without waiting for HTTP responses. Paste in any number of links to see immediate Valid or Invalid badges for each one. It's a great way to clean up spreadsheet data or double-check links in your CMS before you hit publish.
Parse Complex URLs into Components
Reading long URLs with multiple query parameters and fragments can be a headache. The parser separates the protocol, hostname, path, and other components into clearly labeled rows. You'll find query parameters in their own section, with every key-value pair listed separately so you can easily inspect UTM codes or API endpoints.
Free URL Checker for Developers, SEO Specialists, and Content Teams
Dead links can damage your search rankings, frustrate users, and hurt your brand's credibility. Performing a quick bulk check before a site update or content launch helps you catch broken links before your visitors do. SEO specialists can use it to audit sitemaps, developers can verify API endpoints, and content teams can ensure resource links in their articles still work correctly. All these features are free to use right away, with no accounts, no watermarks, and no usage limits.
No Signup, No Watermark, No Limits
Get full access to all six URL tools instantly, without worrying about paywalls, premium tiers, or daily quotas. Feel free to download as many CSV reports and validate as many links as your project requires. For your privacy, your data stays in your browser and is cleared once you close the tab.
Client-Side Processing for Privacy
Every tool, from the link checker to the encoder, runs entirely in your browser using JavaScript and the Fetch API. This means your URL lists and results never leave your device or touch a remote server. It’s a secure way to audit internal company links, staging environment URLs, or any address you want to keep private.
