Choose what people can do with your PDF. The file still opens without a password.
Drag & drop your file here
or browse from your device
Decide what people can do with your PDF: printing, copying, editing, commenting, filling forms, and rearranging pages. The file still opens without a password, so nobody is locked out. They simply find those options unavailable.
This is what most organisations mean when they say a document is protected. A report goes out, people can read and print it, but they cannot lift the text out or change the numbers.
When a PDF blocks printing or copying, it is not physically stopping anything. The restriction is a set of flags inside the file that asks the viewer to hide those options, and readers such as Adobe respect them. That is why they work in day to day use.
They are not a lock, though, and it is better to know that than to find out later. Software exists that ignores the flags entirely. If a document genuinely must stay private, a password that is required to open it is real protection, and permissions are not.
Drag the file onto the upload area, or browse from your device.
Set printing, copying, editing, comments, form filling, and page changes one by one.
Nobody needs it to open the file. It exists so the restrictions cannot simply be taken off again.
Save the restricted file. Your original is left untouched.
Add your PDF, choose what should be allowed and what should be blocked, set an owner password, and apply. The new file is ready to download straight away.
No. The file opens normally for everyone. The owner password only stops someone from removing the restrictions again, which is why you should keep it somewhere safe rather than sharing it.
Without one, anyone who has the file could take the restrictions straight back off. The password is what makes them stick.
Yes, and it is important to know that. PDF permissions are a request to the viewer rather than a lock, and software exists that ignores them entirely. They stop honest people from doing the wrong thing by accident. If a document genuinely must stay private, a password that is required to open it is the real protection, and the Protect PDF tool does that.
AES-256, which is the current standard. Older methods such as RC4 are considered weak and are not used here.
Remove the existing password first with the Unlock PDF tool, then apply your restrictions here.
No. Everything runs inside your browser on your own device. Your file is never sent anywhere, and nothing is stored.
No. Your original PDF stays exactly as it is. The tool creates a new file for you to download.
Yes. It is completely free with no sign-up and no limits.
