Unlock PDF: free online, fast and secure
Banks, telecom companies, the income tax department and employers send password-protected PDFs, usually with your date of birth or PAN as the password. Typing it every time is annoying, and many tools cannot merge or edit locked files.
Enter the password once and this tool saves an unlocked copy. It also removes owner restrictions that block printing or copying. You must know the password; this is not a password cracker.
How to use Unlock PDF
- Upload the locked PDF. Choose the protected file.
- Enter the password. Type the password you use to open it. Leave empty if it opens without one but blocks printing.
- Unlock. Download the unlocked PDF.

Good to know
There are two kinds of PDFs: digital PDFs created from Word, Excel or a website, which contain selectable text, and scanned PDFs, which are just photos of paper pages. Tools that edit pages, like Unlock PDF, work with both. Tools that read text work only with digital PDFs. If you can select a word in your PDF viewer, your file has a text layer.

How Unlock PDF keeps your PDF documents private
When you add a file to Unlock PDF, it is opened with your browser’s own engine, processed in memory and offered back to you as a download. ConvertKaro never receives a copy. This is why the tool is fast even on 4G, why there is no daily limit, and why it is safe for confidential PDF documents like ID proofs, bank documents, contracts and family photos.
