How to use Unlock PDF
- Select the protected PDF.
- Enter the password (leave it empty if the file opens but is restricted).
- Click “Unlock PDF” and download.
Only for files you are allowed to open
bopdf does not crack passwords: you need the correct password to open an encrypted PDF. Files that open freely but block printing or copying (an “owner password”) can be unlocked without one. Please only unlock documents you have the right to use.
🔒 Your files never leave your device
bopdf processes your documents locally with JavaScript (pdf-lib and Mozilla pdf.js) inside your browser tab. Your PDF is never uploaded, stored or seen by us — you can even disconnect from the internet after the page loads and the tool keeps working. When you close the tab, everything is gone.
Frequently asked questions
I forgot the password — can you recover it?
No. bopdf only removes passwords you already know.
Is the file uploaded?
No, decryption happens on your device.
Are my files uploaded to a server?
No. Everything happens in your browser on your own device. Files are never sent over the internet, which makes bopdf suitable for confidential documents.
Is there a file size limit?
There is no fixed limit, but very large files (hundreds of MB) depend on your device memory. On phones, files up to about 100 MB usually work well.
