Unlock PDF — Remove Password from Protected PDF Documents
MakeCard PDF Unlock is a secure, browser-based PDF decryption tool that removes known passwords and encryption locks from protected PDF documents. If you have password-protected bank statements, e-Aadhaar cards, salary slips, or tax returns (ITR-V) that require typing a password every time you view or print them, this tool decrypts the document once and saves an unencrypted copy. Crucially, the decryption runs 100% client-side using your computer or phone’s local processing power—no sensitive documents are ever uploaded to any server.
How to Use PDF Unlock
Select your password-protected PDF document by dragging and dropping it into the upload box or clicking "Choose PDF File".
Enter the valid existing password for the document in the password input box.
Click "Unlock & Save PDF" to initiate local in-browser decryption.
The tool decrypts every page and regenerates a clean, unlocked PDF using client-side PDF-Lib and PDF.js engines.
Click "Download Unlocked PDF" to save your permanent password-free file.

- Common password formats: e-Aadhaar password is first 4 letters of your name in CAPITAL + 4-digit Birth Year (e.g. SURE1992).
- Common bank statement passwords: PAN number in lowercase or uppercase, or first 4 letters of name + DDMM of birth date.
