PDF Security — Password Protect & Unlock PDFs
Protect, unlock and sign PDFs. 2 tools, all free.
About these security tools
PDFs often carry sensitive information — salary slips, bank statements, Aadhaar and PAN scans, contracts. Protect PDF adds a password and encryption so only the people you choose can open the file.
Unlock PDF removes the password from a PDF you already have the right to open — for example a bank statement you need to upload or merge — so you do not have to type the password every time.
Security — frequently asked questions
How do I put a password on a PDF?
Open Protect PDF, upload the file, choose a strong password and download the encrypted PDF.
Can I unlock a PDF without the password?
Unlock PDF is for files you are authorised to open. It is not a tool for breaking into documents that belong to someone else.
Are my files stored?
No. Files are processed and deleted immediately after your download is ready.
