Download CleanThis
Take cleanthis.io with you — check pages, links and downloads without leaving your browser. Everything on this site also works right here, no install needed.
Browser Extension BETA
Free & open source · works with Chrome, Edge, Brave, Opera and Firefox
- Scan the page you're on — a safety verdict and scores in one click, or paste any address to check it before you visit.
- Check a link before you open it — right-click any link and choose "Scan with CleanThis".
- Clean files from your browser — drop a file in and get back a sanitized copy, with the same three cleaning levels as this site.
- Safer downloads — optionally have risky file downloads rebuilt into clean copies before they reach you. You can always keep the original.
- Warnings before dangerous sites — an optional warning page before a flagged site loads. That check happens on your device; the addresses you visit are never sent anywhere.
The extension is in beta and not yet listed on the browser stores, so for now it's a direct download from GitHub — the install steps there take about a minute. That's also where the full feature tour and every line of its source code live.
Desktop and mobile apps are on the roadmap. Until then, the extension and this website are the ways to use CleanThis.
