How we handle your files

Your files stay on your device

Every tool available today runs inside your browser. When you add a file, the page reads it and converts it on your own computer or phone. The file is not sent to our servers or to anyone else.

Each tool page says where the work is done, right under its title: “Processed in your browser”.

What the page downloads

The first time you use a tool, the page downloads the code it needs to read and write each format, such as the WebP decoder or the JPG encoder. That code comes from our own site and only travels from us to you. Nothing about your files travels the other way.

How you can check it

Open your browser's developer tools, go to the Network tab and convert a file. You will see the page download its own code, but no request that sends your file.

Our automated tests check this on every change: they convert files in a real browser and fail if the page sends any request with data or contacts any other site.

What we keep

We do not see, store or keep your files, their names or their contents, because they do not reach us. When you close or reload the page, the converted files are gone from it too.

Tools that will need our server

Some tasks, like converting Word to PDF, cannot be done well in a browser. If a tool ever needs our server, its page will say so before you add a file, and we will update this policy before that tool goes live. None of them is available yet.
