How can free tools be private?
Most online tools upload your file to their servers, process it there and ask you to trust that they delete it. Nolo works the other way round: the website sends the tool to you, and the tool runs in your browser on your own device. Your PDF, photo or video never travels over the internet, so there is nothing for anyone to keep, leak or sell.
That is also why Nolo has no limits and needs no account: your device does the work, so we have no server costs per file to ration. See exactly how it works, or check it yourself: open your browser's network panel while you use a tool and you will see no upload.
