About Toolcloak

Our mission

Most free online tools ask you to upload your files to a stranger's server, create an account, or sit through a wall of ads before you get a result. We think everyday tasks like compressing a photo, formatting JSON or generating a QR code should not cost you your privacy or your time.

Toolcloak exists to give people a clean, honest alternative: pick a tool, use it, get your result. That is all.

More than single tools

Tool Chains let you run several tools one after another (for example compress photos, then turn them into a PDF). History, Saved files and a Wishlist of starred tools are kept on your own device, and the site can be installed as an app and used offline once loaded.

Privacy first, by design

Almost every Toolcloak tool processes your data locally using modern browser technology. Your text, images and files stay on your device. We do not run an upload pipeline, so there is nothing for us to store, sell or leak. Read our Privacy Policy for the full details, including the few cases where a third-party service is involved.

Free, with no catch

There is no signup, no paywall, no watermark and no usage limit. Toolcloak is an independent project. If we show advertising in the future to cover hosting costs, it will never get in the way of the tools and will be described clearly in our Privacy Policy.

Who is behind Toolcloak

Toolcloak is built and maintained by an independent developer. New tools are added regularly, and many improvements come directly from user feedback.
