6 Free Link Checkers Tested In 2026 Before You Click Anything

Six free tools claim to tell you whether a link is safe. I tested what each one checks and what happens to the link you submit, to find which one deserves the thirty seconds before you click.

The thirty seconds before you click any link

For a suspicious link, Google’s free Safe Browsing site status checker is the fastest first move: no account needed, and an answer back in seconds, the same whether you’re checking from Mumbai or Manchester. Run that first. If the link is shortened or still feels wrong, follow up with VirusTotal or urlscan.io before you open it anywhere.

Takeaways

  • Google’s free Safe Browsing site status checker needs no account and returns a result in seconds, making it the fastest first check for a suspicious link.
  • VirusTotal’s free public API is limited to four requests a minute and shares submitted files with partner antivirus vendors unless you pay for Private Scanning.
  • urlscan.io’s free plan allows up to 5,000 public scans a day, but a public scan is visible to anyone searching the site, so never submit a link containing a password reset code.
  • Microsoft Defender SmartScreen runs automatically on Windows Pro, Enterprise, Pro Education and Education editions with Microsoft Edge, so it is already protecting you before you paste a link anywhere.
  • If you already clicked a suspicious link, the FTC recommends updating your security software and running a full scan immediately, then changing the password on any account the page imitated.
VirusTotal limit 4 requests a minute on the free public API
urlscan.io quota Up to 5,000 public scans a day on the free plan
SmartScreen cost Free, built into Windows Pro, Enterprise, Pro Education and Education
Account needed None for Google Safe Browsing, Bitdefender or NordVPN

How do you check a link safely?

You check a link safely by running its address through a lookup tool instead of opening it in a browser tab. Paste the full URL into Google’s Safe Browsing site status checker, which searches its blocklist and tells you in seconds whether that address is currently flagged for malware or phishing, with no account needed (Google Safe Browsing site status). On a laptop, hover over a link without clicking to see where it leads, since the visible text and the true destination are often different; the Cybersecurity and Infrastructure Security Agency lists this mismatch as one of the clearest signs of a spoofed link (CISA phishing guidance). On a phone, a long press on the link usually shows the same preview.

What makes a link look malicious?

A malicious link usually gives itself away through the domain, not the words around it. Watch for an extra word stitched into a familiar brand name, or a domain ending that doesn’t match the company, such as a bank using .info instead of .com; CISA lists both as common spoofing patterns (CISA phishing guidance). A shortened link that hides the true destination until you click is another sign, and so is urgent wording built to push you into acting before you can check anything. AI tools have made the spelling mistakes that used to give phishing away mostly disappear, so checking the domain itself carries more weight than before. I cover what that looks like in How To Spot An AI-Written Phishing Email Before You Click.

What if you already clicked it?

If you already clicked a suspicious link, treat it as a two-part problem: your device and your accounts. The FTC’s guidance is to update your computer’s security software immediately and run a full scan to catch anything that installed itself in the background (FTC phishing guidance). If the page captured any personal information, IdentityTheft.gov walks through recovery steps specific to what was exposed, according to the same FTC page. Change the password on any account the page impersonated, and turn on two-factor authentication where you haven’t already. In India, report the link through the government’s National Cyber Crime Reporting Portal, which also lets you search whether a number or email tied to the scam has been reported before (cybercrime.gov.in).

Six link checkers, ranked by what they catch

Ranked by how much of a threat each one surfaces before you click, from broadest coverage to narrowest.

  1. VirusTotal checks a submitted URL against dozens of antivirus and blocklist engines at once, the broadest free lookup here, though the public API allows only four requests a minute (VirusTotal API overview, Oct 2026).
  2. urlscan.io visits the page in an isolated sandbox and records what it does, catching live attacks a blocklist alone would miss; the free plan allows up to 5,000 public scans a day (urlscan.io pricing, Oct 2026).
  3. Google’s Safe Browsing gives an instant answer against a blocklist Google says helps protect over five billion devices a day, a vendor claim, though it only flags sites already identified once (Safe Browsing overview).
  4. Microsoft Defender SmartScreen works in the background on Windows and Edge, checking every URL automatically, though it only ships with Windows Pro, Enterprise, Pro Education and Education editions (Microsoft Defender SmartScreen overview, Oct 2026).
  5. NordVPN Link Checker runs a link through a proprietary machine learning model built to catch new phishing patterns, with no account or subscription required, per NordVPN’s launch announcement (NordVPN Link Checker launch).
  6. Bitdefender Link Checker scans for malware, phishing, scam pages and look-alike domains, and expands shortened links automatically, free with no stated cap (Bitdefender Link Checker).

Which free checker should you use?

For the thirty seconds before you click, Google’s Safe Browsing site status checker is the one to default to: it needs no account and returns an answer in seconds, from any browser. It will miss a link that’s malicious but not yet reported, which is where the other five tools come in for a second opinion.

Dimension VirusTotal urlscan.io Google Safe Browsing Bitdefender Link Checker NordVPN Link Checker Microsoft SmartScreen
Free use Public API and web lookup, non-commercial only Free tier, daily cap Fully free, no limit stated Free, no cap stated Free, no account Free, built into Windows
What it checks Dozens of antivirus engines at once Live sandbox visit and behavior Google’s own blocklist Malware, phishing, fraud, look-alikes Proprietary phishing model Cloud reputation list
Privacy of submission Shared with AV partners unless paid Public scans are searchable by anyone Just a lookup, nothing submitted Not stated beyond general policy Not stated beyond launch notes Local to browser and OS
Speed Seconds for a known link Under a minute Instant Seconds Seconds Instant, automatic
False sense of safety Clean only means not flagged yet Can still miss a delayed payload Only catches sites already reported No detection-rate data published No detection-rate data published Useless on another device

VirusTotal is the better choice once a link has already passed Google’s check but still feels off, since it cross-references far more engines at once. urlscan.io is the better choice when you want to see what a page does before you visit, though a public scan on its free plan is visible to anyone searching the site, so don’t submit a link that contains a password reset code or account token (urlscan.io scan visibility). Bitdefender’s tool is the better choice for a shortened link, since it unwraps the destination automatically. NordVPN’s Link Checker is the better choice if you already use NordVPN and want one brand across your checks, though it offers no functional edge over the others for an occasional check. SmartScreen isn’t something you choose at all: if you’re on Windows with Edge, it’s already running, which is worth knowing so you understand why some bad links never reach you in the first place.

Do these work in India?

All six tools work the same in India as anywhere else, since each one is a website or a built-in feature rather than a service with regional restrictions. None of the six vendor pages publish a rupee price, because all six are free to use. Google’s Safe Browsing checker and Bitdefender’s tool need no account for a basic check, from any device, in any browser. NordVPN’s tool doesn’t ask for one either. VirusTotal and urlscan.io only require a free account for their APIs, and that signup is the same one used worldwide. If a link turns out to be part of a scam, India’s Ministry of Home Affairs runs a dedicated reporting portal where you can file it directly (cybercrime.gov.in).

How private is what you submit?

What happens to a link after you submit it depends on which tool you pick. VirusTotal’s standard scan shares the submitted file or URL with partner antivirus vendors so they can improve detection; a paid Private Scanning tier exists for anyone who doesn’t want that sharing (VirusTotal Private Scanning). urlscan.io ranges from private to public, with an unlisted option between, and only the public setting is searchable by anyone on the site. Google’s checker only performs a lookup against its own list, so there is nothing of yours to share. Bitdefender and NordVPN don’t publish a specific retention policy for a submitted link beyond their general privacy terms.

What’s the catch with free tools?

The catch is that a clean result tells you a link hasn’t been caught yet, not that it’s safe. Every tool here works from a list or a model trained on patterns seen before, so a link built for one target, used once, can pass every check here and still be the one that gets you. That’s also why click-rate numbers from workplace phishing tests say little about how dangerous one specific link is, a point covered in Why Your Phishing Click Rate Tells The Board Nothing Useful. Treat a link checker as one input alongside the domain check and the urgency check above, not a replacement for either. For reasoning through all three at once, a well-built prompt beats a one-line question to an assistant; see Fix Lazy AI Answers With Three Lines Added To Every Prompt.

Prompts you can use

Paste these straight in. Change the parts in square brackets and nothing else.

Interpret a link scan result
You are a patient security analyst helping someone who is not technical understand a link-scanning report. I'm going to paste the raw result from a link checker below. Read it and tell me, in plain language: (1) whether any engine or indicator flagged the link, (2) what specifically was flagged and what that means in practice, and (3) whether this looks like a safe result, an uncertain result, or a clear warning. Avoid security jargon, and if a term is unavoidable, explain it in the same sentence. If the report is incomplete or you need more of it to judge, ask me for the missing part before giving a verdict.\n\nHere is the result: [paste result]

Paste the real report text, since the model can’t fetch the link itself.

Decide whether to open a link
Act as a careful second opinion before I open a link I'm unsure about. Here's what I know: the link is [paste link or describe it], it arrived via [email, text, social media, or other], and here's what a checker tool told me: [paste results, or say 'I haven't checked yet']. Based on the domain spelling, the urgency of the message, and what the checker found, tell me whether you'd open it, and explain your reasoning in two or three sentences. If you don't have enough information to judge confidently, say so and tell me exactly what detail would change your answer, rather than guessing.

This gives you a second read, not a guarantee; run at least one checker tool from this article first.

Build a post-click recovery checklist
I may have clicked a suspicious link and want a clear, ordered checklist of what to do in the next hour. My situation: device is [phone, laptop, or work computer], I [did or did not] enter a password or personal information on the page, and the page was impersonating [company, bank, or service name]. Give me a numbered checklist covering my device, my accounts, and who to notify, in priority order, with the most time-sensitive step first. Keep each step to one sentence. Ask me any clarifying question you need before finalizing the list.

Treat this as a starting checklist, not a substitute for your bank’s fraud line or your IT team if it’s a work device.

Questions people actually ask

Does VirusTotal share my files with other companies?

Yes, on VirusTotal’s standard free scan, submitted files and URLs are shared with partner antivirus vendors so they can improve detection, according to VirusTotal’s own documentation. A paid Private Scanning tier exists specifically for people who don’t want that sharing, since the free scan and API don’t offer that option.

Can I check a link for free in India without an app?

Yes. Google’s Safe Browsing site status checker, Bitdefender’s Link Checker and NordVPN’s Link Checker are free websites that work the same in India as anywhere else, and none require an account or app download for a basic check, based on each vendor’s own page.

Will a clean link checker result guarantee a link is safe?

No. Every tool on this list checks a link against a list or a model trained on patterns seen before, so a newly built link used against a single target can pass every check and still be dangerous. Treat a clean result as one input, not a guarantee.

What’s the difference between urlscan.io and VirusTotal?

urlscan.io visits the page in an isolated sandbox and records what it does, including redirects and scripts, while VirusTotal cross-checks the URL against dozens of antivirus and blocklist engines without visiting the page itself. Use urlscan.io to see behavior, and VirusTotal for the broadest blocklist coverage.

Does Windows SmartScreen replace the need for a link checker?

No. SmartScreen runs in the background on Windows Pro, Enterprise, Pro Education and Education editions with Microsoft Edge, checking URLs and downloads automatically, according to Microsoft’s own documentation. It protects you passively, but won’t help you check a link on a different device, browser or operating system.

What happens next

Expect these checkers to lean harder on behavior analysis rather than static blocklists, since AI-written phishing pages now update faster than any list can track them. Watch whether urlscan.io or VirusTotal add a clearer free-tier privacy default, since right now the visibility setting you choose is the biggest risk in using them well.

Full resume rewrite, section by sectionBest on Claude
Act as a blunt hiring manager who has read ten thousand resumes, not a career coach. I will paste my full resume and the job description I want. Rewrite the whole resume for that role, section by section, in this order: summary, experience, skills, education. Rules: every experience line leads with impact, not duty. Use bracketed placeholders like [8 percent] for any number I did not give you, and list at the end every placeholder I need to replace with a real figure. Keep it to one page of text. Plain formatting only, no tables or columns, so screening software can parse it. After the rewrite, tell me the three weakest claims that need evidence before I send this anywhere. My resume: [paste resume]. The role: [paste job description].
