Useful by design

Less setup. More getting things done.

From a smaller PDF to a finished invoice, choose a tool, add your input, and review the result. Explore files, images, calculations, office tasks, and developer utilities in six languages.

Open and get started

Public tools are free to use in a modern browser. No desktop installation is needed.

Know where your data goes

Many tools process files locally. Tools that connect to external services explain this on their page; accounts, comments, and anonymous analytics still make site requests.

Your language, your settings

Choose from six interface languages. Currency, units, and country-specific options remain separate choices in each tool.

A few things worth knowing

Are these tools free?

Yes. Public tools are free to open and use. File sizes, supported formats, and browser requirements vary by tool and are explained on its page.

Do my files leave my device?

Many file and calculation tools do their core processing in your browser. Some features need an external connection. Check the processing notice on the tool page before working with sensitive data.

What is saved in “recent tools”?

This list stores only the identifiers of up to six tools you opened, in this browser. It does not contain file names, inputs, or outputs. You can clear it here; clearing it does not delete separate account history.
