How to remove a password from a PDF (when you know it)
By the PdfDady team · Updated · 7 min read
If you know the password, removing it takes under a minute: open the PDF in a tool that can re-save it without encryption, type the password once, and download a copy that opens freely. If you don't know the password, no honest tool can remove it for you. That is the whole point of a password.
Our Unlock PDF tool does the first job in your browser, so the file and the password are not uploaded anywhere. The rest of this guide covers the steps, the two different kinds of PDF lock, and what to do with the unlocked copy afterwards.
The steps
- Open Unlock PDF and add your file. It accepts one PDF of up to 100 MB.
- Type the password you normally use to open the file. It is checked in your browser. PdfDady doesn't store it or send it.
- Download
unlocked.pdf. This copy opens without asking for anything.
Your original file is not changed. You now have two files: the protected one you received, and a new one with no password.
Only the encryption is removed. The pages, text, links and bookmarks stay exactly as they were, so the unlocked copy looks identical and the text can still be selected and searched.
Two kinds of lock, and why they behave differently
PDFs can be locked in two ways, and it helps to know which one you have.
| What happens | What it is | What you need |
|---|---|---|
| The PDF asks for a password before showing anything | An open password | The correct password |
| The PDF opens, but printing, copying or editing is greyed out | Restrictions (a permissions password was set) | No password; use Remove restrictions |
An open password encrypts the contents. Without it, the file is unreadable noise, which is why nothing can be done if you don't have it.
Restrictions are different. The file opens for everyone, and the PDF simply carries a note asking readers not to allow printing or copying. Most PDF readers respect that note, but it is a request rather than a lock on the content. In Unlock PDF, add the file and press Remove restrictions. No password is asked for.
Use this only on files that are yours, or that you have permission to change. A form you filled in, your own statement or your own project report is fine. Removing protection from someone else's document without their say-so may not be allowed.
If you have forgotten the password
We can't help, and we would rather tell you that plainly than waste your time. PdfDady never guesses or recovers passwords, and you should be wary of any site that promises it can. Sending a locked bank statement to an unknown service is a bigger risk than the inconvenience you started with.
What usually works instead:
- Read the email the file came with. Banks, insurers and government portals almost always explain the password rule in the message body or on the download page.
- Check the official rule. For e-Aadhaar, UIDAI says the password is the first four letters of your name in capitals followed by your year of birth, such as SURE1990 for Suresh Kumar born in 1990. For bank files, see our guide to bank statement PDF passwords. For mutual fund statements, see the CAS password guide.
- Ask the sender. If a colleague or your CA protected the file, only they know what they typed.
- Download it again. Most statements and certificates can be requested afresh from the issuer, often with a password you choose.
When the correct password is refused
Usually the password is right in your head and wrong on the keyboard. Check these before giving up:
- Capitals. PDF passwords are case-sensitive.
SURE1990andsure1990are different passwords. - Phone keyboards. Your phone may capitalise the first letter or add a space after a word. Type slowly and look at what was entered.
- Date formats. A date of birth might be wanted as DDMM, DDMMYY or DDMMYYYY. The email that came with the file says which.
- Similar characters. The letter O and the digit 0, or a lowercase l and the digit 1, are easy to swap.
- The name on record. Rules that use your name mean the name as the issuer has it, which may differ from how you usually write it.
One more case: some PDFs are locked with a digital certificate instead of a password. Unlock PDF does not support those.
What changes in the unlocked copy
Two things are worth knowing before you delete the original.
Digital signatures will show as invalid. Removing encryption means rewriting the file, and a digital signature only vouches for the exact file that was signed. An e-Aadhaar PDF, for example, is digitally signed by UIDAI. The unlocked copy is fine for printing, but keep the original download for anyone who needs to check the signature.
The copy has no protection at all. Anyone who gets the file can read it. That sounds obvious, but it is easy to forget once the file is sitting in your Downloads folder next to forty others.
Storing the password-free copy
A password on a statement was doing a small but real job. Once it is gone, take over that job yourself.
- Keep the unlocked copy only as long as you need it. If you unlocked a statement to upload it to a loan portal, delete it after the upload.
- Don't leave it on a shared or office computer, or on a cyber café PC. Remove it from Downloads and empty the recycle bin.
- Think before forwarding it on WhatsApp or email. The copy you send lives on in the other person's phone and inbox.
- If you want to keep it long term, add a password you will remember with our Protect PDF tool. You get the convenience of your own password in place of the bank's formula.

Other ways to do the same thing
You don't need our tool for this. Many browsers and PDF readers let you open the file with its password and then print it to a new PDF, which also produces a copy without the password. It works, with two drawbacks: bookmarks and links may be lost because the pages are re-created, and it won't work if printing itself is restricted.
Whatever you use, the test is the same. If the tool asks you to upload a locked financial document to a server, ask yourself whether you are comfortable with that. Our explainer on whether online PDF tools are safe shows how to judge.
Questions people ask
Can I remove a password from a PDF on my phone?
Yes. Unlock PDF runs in the phone's browser, so there is nothing to install. Add the file from your phone's storage, type the password and save the new copy.
Is it legal to remove a PDF password?
Unlocking your own files, or files you have permission to unlock, is the safe ground. A password on your own bank statement exists to protect you during delivery, and removing it for your own use is a personal choice. Someone else's protected document is a different matter.
Will the unlocked PDF look any different?
No. Only the encryption is removed. Pages, text, links and bookmarks are kept.
Why does the portal reject my password-protected PDF?
Many upload portals can't read encrypted files, so they refuse them or show blank pages. Upload an unlocked copy, then delete that copy from your device once it has gone through.
Can I unlock several PDFs at once?
The tool takes one PDF at a time. For six monthly statements, unlock each one and, if you need a single file, combine them with Merge PDF.
