PDF Mikata

Add a Password to a PDF

Before you send an important document.

Your PDF is never uploaded. Everything is processed on this device.

  1. 1Choose a PDF
  2. 2Set a password
  3. 3Save the PDF
Done

🔒 Your files are never sent to an external server. Everything is processed safely inside this browser.

How to use

  1. Choose a PDF with "Choose a PDF".
  2. Enter the password twice, once to confirm.
  3. If needed, choose to restrict printing, copying or editing, then press "Add the password" and save.

How it works

  • Adds a password needed to open the PDF, with AES-256 encryption.
  • You can also restrict printing, copying text and editing.

Notes

  • If you forget the password, the PDF cannot be opened.
  • It is safer to share the password separately, for example by phone or another message.
  • The first time, it loads the processing program (about 1.3 MB).

FAQ

Are my PDF or password sent anywhere?

No. Both stay inside the browser on your device.

Will every app respect the restrictions?

Printing and copying restrictions depend on the app that opens the PDF. Some apps may ignore them.
