Broken Link Checker
Open the tool, complete the task, then come back to this guide if you want alternatives and troubleshooting tips.
Introduction
I’d handle “broken link checker online” in two passes: get the result with Broken Link Checker, then verify the boring details. File size, page order, spelling, numbers. That’s where mistakes usually hide. How to check broken links: Enter a page URL (blog post, landing page, sitemap entry). Set the link limit (5-80). Click Check links — the tool extracts every <a href> on the page and probes each. Filter results by working or broken.
Scan any page, extract its links, and HEAD-check each one for 4xx / 5xx errors.
Utility tasks sound small until they block you: a weak password, a missing thumbnail, a file that won't upload, a link that needs sharing. This guide gives you the short workflow first, then the checks that prevent rework.
How to check broken links
Step 1
Enter a page URL (blog post, landing page, sitemap entry).
Step 2
Set the link limit (5-80).
Step 3
Click Check links — the tool extracts every <a href> on the page and probes each. Filter results by working or broken.
Method 1: Using OneClickUse Broken Link Checker
Open Broken Link Checker. Add the file, text, link, or numbers the tool asks for. If there are options, change only the ones you understand; defaults are there for a reason. Then download or copy the result and compare it with the original.
I’d also do one small check before moving on: enter a page url (blog post, landing page, sitemap entry). That sounds obvious, but it catches a surprising number of bad uploads and wrong calculations.
If this is part of a bigger task, pair it with the related tools below instead of starting over in another app. For example, a PDF task may need compression after merging; an image task may need resizing before compression; a writing task may need word count after cleanup.
Method 2: Use a manual or desktop method
Manual methods work, but they're fiddly. You can build passwords by hand or extract IDs from URLs yourself, but small mistakes are easy to miss.
This route is best when you already know the app and only have one item to fix. If you're doing the same thing twice, or you're on a deadline, the manual path starts to feel slow.
Method 3: Use paid professional software
Paid utilities are useful when you need storage, syncing, monitoring, or team controls. For a quick generated result, free is fine.
My rule of thumb: pay when the tool saves you repeated work or reduces real risk. Don't pay just because a search result made the simple option look complicated.

FAQ
Why only 80 links per scan?
Each link is a separate HTTP probe with timeout. Limiting keeps response time reasonable. For full-site crawls, use a desktop tool like Screaming Frog.
Why does Twitter / Facebook show as broken?
Some sites block HEAD requests or return 403 to scripted user-agents. They work in a browser but the checker correctly flags them as unreachable.
Are 301 / 302 redirects flagged as broken?
No — 3xx is considered working. The 'broken' bucket is for 4xx (404, 410, etc.) and 5xx errors.
Final take
For most people, the fastest route for “broken link checker online” is to use Broken Link Checker, check the result, and move on. Keep desktop or paid tools for advanced edge cases, but use OneClickUse when you want a quick, free, browser-first workflow.
