Pick a tool. Nothing installs, nothing uploads.

How the privacy guarantee works

In your tab

The PDF engine is JavaScript and WebAssembly that downloads once, like any web page. Your files are opened by your own browser — not by our servers.

Verifiable

Don't take our word for it. Open DevTools → Network while you work: zero upload requests, on every tool, every time.

Works offline

Once a tool has loaded you can switch off Wi-Fi and keep working. Airplane mode is the strongest privacy guarantee there is.

Frequently asked questions

How do I know my file isn't uploaded?

Open your browser's developer tools (F12 → Network tab) before choosing a file. You'll see no upload requests while a tool runs. You can also switch off your network first — once the page has loaded, every tool keeps working.

Is it really free — what’s the catch?

There is no catch and no premium tier. The site is paid for by the labelled display ads you can see on the page. No task limits, no file-size caps, no watermarks, no account.

Do you store or see my documents?

We cannot. There is no server to store anything on: the site is static files, and the processing runs in your browser tab. Close the tab and the file is gone from memory.

Do you use cookies or analytics?

No cookies and no account system. If we ever add analytics it will be a privacy-preserving, cookieless service — never Google Analytics, which would contradict the entire point of this site.
