You do not have to take our word for it
-
Watch the network
The "Nothing is uploaded" button in the app opens a list of every other site the page has contacted since you opened it, and how often, taken from the browser's own record. Your browser's developer tools show every request, this site's own included.
-
Pull the plug
Once the app has loaded, turn off your network and keep working. Text recognition, the document converter and the handwriting fonts work offline too after their first use.
-
Redaction that removes
A page with something blacked out is saved as a picture of itself, so the text under the box is gone, and every redacted page is checked before the file is saved.

- Is it free?
- Yes. Protect PDF is one of the everyday tools, free forever, with no account and no watermark.
