Your files stay on this computer.

Not Only PDF is a set of file tools that run inside your browser. Nothing is uploaded, because there is no server to upload to.

Why this one

• Nothing is uploaded. The file is read by code running on your own machine.
• No account, and nothing to sign up for.
• No waiting on an upload, and no queue — the work happens here.
• Free, with no paid tier and no commercial licence, ever.
• Open source, so the claim above is checkable rather than asserted: the code is public, and so is the reasoning behind it, including the decisions that turned out to be wrong.

How this works, and how you can check it — what crosses the boundary, what does not, and how to watch for yourself in your browser's network tab.

Not Only PDF is being built in the open and is not finished. Every tool listed above works today; a tool is only linked once its page ships. Redaction is still to come, and it is the one this project is most careful about.
