Add a password and set what readers may do.
No file to hand?(sample-invoice.pdf · made-up data)
Lifts every restriction below. Defaults to the open password.
At full quality.
Select-and-copy, and screen readers keep access regardless.
Editing, and rearranging pages.
Sticky notes, highlights, fields.
Restrictions are honoured by well-behaved readers; the open password is what actually keeps the file closed.
A password to open the file, an owner password to lift the limits, and a choice of what a reader may do: print, copy text, change the document, add comments. The encryption is AES-256, the only cipher the current PDF standard still recommends, and it is applied here — the file is not sent anywhere to be locked.
Drop in the PDF you want to lock.
Set the password needed to open it, and confirm it.
Optionally set a separate owner password, and choose what a reader may do — print, copy, edit, comment.
Click Protect and download the encrypted PDF.
No. Toolpit does not upload your file for processing — the tool runs as code in this browser tab, works on the copy your browser opened, and forgets it when you close the tab. You can check this yourself: open your browser’s network panel and run the tool. You will see the page, its scripts and the ads on the site, and — when you save, if you are signed in — one small request that charges 10 tokens to your account. None of them carries your file, its name or anything read from it, because file processing stays on your device.
AES-256, which is the only algorithm the current PDF standard still recommends and the same class of encryption used to protect disks and banking traffic. The document is genuinely encrypted, not merely marked as restricted: without the password the bytes are unreadable, including to us, because the encryption happens on your device and the password is never sent anywhere.
The open password is required to read the document at all. The owner password lifts the restrictions — printing, copying, editing — for whoever has it. Setting only an open password gives you a file nobody can read without it. Setting an owner password as well lets you hand out a file people can read but not, for example, print at full quality.
Honestly, no — and it is worth knowing why. Permissions are a flag in the file that well-behaved readers choose to respect; a reader that ignores them can. The open password is the part with real teeth, because without it there is nothing to read in the first place. Treat the permissions as a clear statement of intent, not a lock.
No. That is the point of encryption working properly — there is no master key, no backdoor and no recovery. Unlock PDF can remove a password you know; nothing here can guess one you do not.
Every one of these runs in your browser too — no upload, no watermark.
