About
This is a free online tool site. It does one thing: turn the small utilities you occasionally need — but don't want to install software or create an account for — into pages that just work.
What sets it apart from most similar sites is that most tools here **finish computing inside your browser**, so what you paste never leaves the device. The 1 tools that do need a server are labelled as such on their pages.
Why this site exists
The usual approach for online tools is to send the content to a server. That is easier technically, but it means you have to trust the operator: trust that nothing is stored, nothing is logged, nothing is sold. That kind of trust cannot be verified — only believed.
Here the computation moves into the browser. Not because we are more trustworthy, but because this way **you don't have to trust us**: open the Network panel in your developer tools and watch that nothing is sent while you paste.
How “input never leaves your browser” works
Every tool marked as client-side ships its whole implementation as JavaScript that runs in your browser; it calls no backend endpoint. Formatting, converting, diffing and generating only ever needed local compute anyway.
The few tools that do need a server — reading request headers, calling a model — are clearly labelled on their pages, and every request they make is listed one by one on the privacy page.
How you can verify it
Don't take this text on faith. Open any tool page, press F12, switch to the Network panel, clear it, then paste something in.
If the tool is marked client-side, the Network panel should stay empty. That is a fact you can re-check on the spot, not a promise.
Free, and what comes next
Every tool is free right now, with no sign-up and no usage limits. The site runs on minimal cost (static pages plus a few functions), which is what makes staying free possible.
If advertising is introduced later, it will sit in its own block outside the tool interaction area, and none of the privacy statements above will change — analytics and ad behaviour will be registered on the proof page too.
