Does this guarantee a URL is safe or malicious?+
No tool can. We surface structural red flags — punycode, brand impersonation, suspicious TLDs — that correlate strongly with phishing, but a clean URL can still host a malicious page.
What is a punycode / homograph attack?+
Attackers register domains with Unicode characters that look identical to Latin letters (e.g. 'аpple.com' with a Cyrillic 'а'). Browsers render them in Punycode (xn--) which we detect.
Why are .zip and .mov flagged?+
Those TLDs collide with common file extensions, so a link like 'invoice.zip' is ambiguous between a file and a domain. Attackers exploit that confusion.
Can I check the link without visiting it?+
Yes. This tool only parses the URL string — it never fetches the page. For a deeper look use the URL Redirect Tracer to see where it ultimately points.
Do I need to create an account to use Toolzer?+
No. Every utility on Toolzer is free, anonymous, and works in any modern browser without registration. You will never see a paywall or a forced sign-up flow — the goal is to give you the answer on the first screen and let you move on.
Is Toolzer safe to use with sensitive inputs?+
Yes. Whenever the tool can produce an answer entirely in the browser — password generation, JSON formatting, regex testing, hashing, text counting — the data never leaves your device. When a server lookup is unavoidable (DNS, WHOIS, geolocation), the request is proxied through Toolzer's edge so the upstream service never sees your real IP address.
Does Toolzer work on mobile?+
Yes. The interface is fully responsive and works on iOS Safari, Android Chrome, Samsung Internet, and every other up-to-date mobile browser. You can pin the page to your home screen for one-tap access.
Can I link to or bookmark a result?+
Yes. Every Toolzer page has a clean, permanent URL you can bookmark, share, or paste into a ticket. Results are generated client-side on each visit, so the link always shows fresh data instead of a stale screenshot.
