Questions about security tools
Are the security tools free to use?
Yes. All 5 tools in this category are free, need no account and have no usage limits. ToolzKit is funded by keeping the site cheap to run, not by gating features.
Does my data get uploaded anywhere?
Every tool in this category runs its processing in your browser using ordinary JavaScript. Your input is not sent to a server, and it is not written to storage when you leave the page.
Can I use these tools on a phone?
Yes. The layouts adapt to narrow screens, editors stack vertically instead of side by side, and copy buttons stay reachable without horizontal scrolling.
How do I find a tool quickly?
Press the forward slash key, or Ctrl+K on Windows and Cmd+K on macOS, to open the command palette from any page. Type a few letters and press Enter.
