How it works & privacy
🔒 Everything runs in your browser
Every tool on ToolKettle works entirely on your device. When you format JSON, resize a photo or generate a password, the work happens in your browser. Nothing you type, paste or upload is sent to a server.
🙅 No accounts, no ads
There's nothing to sign up for and there are no ads — ever. The tools are free to use as much as you like.
📊 Anonymous visit counts only
To learn which tools are popular, we count anonymous page visits with Cloudflare Web Analytics. It uses no cookies, collects no personal data, and never sees anything you type or upload.
⚡ Fast by design
Pages are plain HTML that load instantly. Each tool loads only the code it needs, and once a page is open the tool works even if your connection drops.
