How kittybin works

kittybin is a bin full of tools for everyday digital jobs. Here is how it works, and what we promise.

Your files stay on your device

When you convert an image, merge a PDF or format some JSON, the work happens inside your browser. Your files are read on your own device and never sent to our servers. Close the tab and they are gone.

You can check this yourself: open your browser's developer tools, switch to the Network tab and use any tool. No file leaves your device.

Free, with no sign-up

Every tool is free. There are no accounts, no trials and no watermarks. Open a tool and get the job done.

No ads, ever

kittybin has no ad networks, no trackers and no cookie banners, and it never will. We count page views without cookies so we know which tools people use, and that is all.

Fast, because it runs on your device

There is no upload to wait for and no queue. Most tools are ready the moment the page loads, and many keep working when your connection drops.

Made with care

Every tool is built and tested by the kittybin team before it ships, and we keep improving them. You can follow along in the changelog.
