The PDF Workbench interface: a list of tools down the left, page thumbnails in the middle, and a signature being placed on a document.

Don’t take my word for it

Privacy claims are cheap. These are the ones you can check yourself in about a minute.

Pull the plug

Turn off your wi-fi and use it anyway. Every tool still works, because there was never a server on the other end.

Watch the network tab

Open DevTools, press Network, and run any tool. Your file produces no requests. Nothing is sent because nothing needs sending.

Read the downloaded file

It’s one HTML file. Open it in a text editor and search for firebase, fetch( or analytics — the download contains no tracking code at all.

What this page counts

The hosted version counts anonymous visits and which tool was pressed, so I can tell whether this is worth maintaining. Never a filename, never a byte of a document. Do Not Track is honoured, and the downloaded copy counts nothing.

Two ways to use it

Same tool either way. Pick whichever suits how you work.

Use it in the browser

Nothing to download. Open it and drop a PDF in.

Keep your own copy

One file. Save it, double-click it, use it forever — on a plane, on a locked-down office laptop, wherever.
