Questions
Is it really free, with no sign-up?
Yes, completely. There's no sign-up, no login and no daily limit: just open the page and start. It works in your browser on any computer, phone or tablet with nothing to install, and your files are never uploaded — everything happens on your device.
Can a forgotten password be recovered?
No — that’s what makes it secure. Keep the password somewhere safe.
Are my PDFs uploaded?
No. They’re processed in your browser, on your device, and never sent anywhere.
