The awkward moment is small and routine. Four scans need merging. A bundle needs numbering. A form needs filling. The obvious tools are free web converters, and every one of them begins by asking you to hand over the file.

That is not a failing on their part — it is their architecture. Converting a PDF on a server costs real money, so the file has to reach the server, and once it is there the usage has to be metered, which means an account, which means a subscription. Every constraint follows from the first one.

So we moved the work to where the document already is. Modern browsers can parse and write PDFs perfectly well on their own. Once the processing happens on your machine, the whole chain of consequences unwinds: nothing to upload, nothing to meter, no account to create, no reason to charge, and no server that could be breached because there is no server.

What we believe

A privacy claim you cannot check is marketing

We do not say "zero bytes transferred", because the application itself has to reach your browser once and that would be a lie you could catch in thirty seconds. We say something narrower and true: your documents never need to be uploaded. The source is public, the Content Security Policy is enforced by your browser rather than by our good intentions, and the app carries a monitor that lists every request the page has made.

Refusing beats faking

If we cannot safely rewrite a PDF, the app stops and tells you, and your original is untouched. It will never hand you a file that looks right and is quietly broken. This costs us features. A tool that silently corrupts a contract or a medical record is worse than no tool at all.

We would rather say "not yet"

Permanent redaction is the feature most people ask for and we have not shipped it, because a black rectangle drawn over selectable text is not redaction — it is a trap that has embarrassed governments and law firms with real consequences. When it ships it will remove content from the page structure and then verify the removal, and not before. The roadmap says plainly what exists and what does not.

How it is funded

By adverts on the information pages, and nothing else. Serving static files to a lot of people costs very little, and the expensive part — processing your document — happens on your computer at your expense, which is roughly nothing. There is no free tier because there is no paid tier. The information pages carry adverts, which you can decline, and which never run inside the editor. We run no analytics of our own and have no data to sell because we never receive any.

If that changes we will say so on this page before it changes anywhere else.

How you can check us

A privacy claim you cannot test is just advertising, so the important ones here are enforced by your browser rather than by our intentions.

The Content Security Policy. The editor is served with a policy permitting no third-party origin at all. Your browser blocks transmission whatever our code attempts. Read the response headers yourself.
The network tab. Load a document, edit it, export it. After the application files arrive there is no further traffic.
Disconnect. Pull the connection and keep working. Software that needed to send your file somewhere could not.
