Your bank sends statements as password-protected PDFs. So does your payroll provider. Every month you type the same password (often your date of birth or the last digits of an account number) just to read a document you already own. Or you try to upload one to a mortgage or tax portal and it gets rejected because the file is encrypted.
If you know the password, you can save a copy without it. That's all this guide covers. If you've forgotten the password, skip to the section on forgotten passwords, because no honest tool can get you in.
A PDF can have two different passwords
The PDF format defines two passwords, and they do very different jobs.
The open password (the spec calls it the user password) is the one that pops up a box before you see anything. When it's set, the contents of the file are encrypted. Without the password the reader has nothing but scrambled bytes, so there's nothing to show you.
The permissions password (the owner password) is different. A file can have one without having an open password at all. It opens normally, but the reader refuses to let you print, copy text, fill forms or edit. The contents are still encrypted on disk, but the key needed to decrypt them can be worked out without knowing the owner password. That's by design: every reader has to be able to display the page. The restrictions are a flag in the file saying "please don't allow printing", and it's up to the reader app to respect it. Adobe Acrobat Reader and Preview on Mac do. Plenty of other software doesn't.
So a file can be in one of three states:
- An open password only, or an open password plus restrictions. You need a password to read it at all.
- Restrictions only. It opens fine, but printing or copying is greyed out.
- Certificate security, where the file is locked to someone's digital ID instead of a typed password. This is rare outside corporate and government setups.
Why you'd want the password gone
The usual reason is repetition. A year of monthly statements is twelve files, and each one asks for a password every time you open it. If you keep them in a folder that's already private (an encrypted laptop, your own account in a cloud drive), the extra password doesn't add much. It mostly slows you down.
The other reason is compatibility. Many upload forms (loan applications, visa portals, accounting software, some HR systems) can't read encrypted PDFs and fail with a vague error. Merging tools and printers at copy shops can choke on them too. A clean copy without encryption just works.
Restriction-only files are a separate annoyance. A form you're supposed to fill in won't accept typing, or a document you need to quote won't let you copy a paragraph. Removing the restrictions fixes that.
How to remove it on EddiesPDF
- Open Unlock PDF and drop your file onto the page, or click to pick it.
- The tool checks the protection and tells you what it found, for example which encryption is used and what's restricted.
- If the file has an open password, type it in the password box. The open password or the permissions (owner) password works, so use whichever one you have.
- If the file only has restrictions, you'll see "No password needed. Only the restrictions will be removed." There's nothing to type.
- Click Unlock PDF and download the new copy.
The copy has no password and no restrictions. Your original file is untouched, so you still have the protected version if you need it.
Decryption happens in your browser and the file isn't uploaded to our server. Bank statements and payslips are about as personal as documents get, so of everything this tool does, that's the part I'd check first. If you want to read more about how browser-based tools handle files, there's a separate guide on whether online PDF tools are safe.
What this tool won't do
It can't crack or guess a password. If you don't know either password and the file has an open password, Unlock PDF will tell you the password is wrong and stop there. It doesn't try lists of common passwords or run a brute-force attack, and that is deliberate.
That's partly practical. A file encrypted with AES 256-bit and a decent password isn't going to be brute-forced in a browser tab, or anywhere else in a reasonable amount of time. And it's partly a line we don't want to cross. A password on someone else's document is a pretty clear signal that you're not meant to read it.
So use this on files you're entitled to: your own statements, documents sent to you along with the password, files you protected yourself and want an open copy of. Not on a colleague's HR file you found on a shared drive.
It also can't remove certificate-based security. That kind of file is tied to a digital certificate, not a typed password, and the person who protected it needs to send you an unprotected copy.
If you've forgotten the password
Start with where the file came from. For bank and payroll PDFs the password is almost always a fixed pattern, and it's written in the email the file came with or on the provider's help pages. Common patterns are a date of birth in a specific format, part of an account number, or part of your name plus some digits. Check the format carefully: DDMMYYYY and YYYYMMDD look similar when you're typing from memory.
If that doesn't work:
- Download the statement again from your online banking. Most banks let you get past statements from their website or app, and the copy you download while logged in is often not password-protected at all.
- Ask the sender for a new copy. An accountant, landlord or HR department can usually re-send it, either without protection or with a password you'll actually remember.
- If you protected it yourself, check your password manager. Some people save these under the file name rather than a website.
Where to keep the unlocked copies
If you remove the password from sensitive files, store the copies somewhere that's protected in a different way: a laptop with disk encryption turned on, or a cloud folder behind your account login with two-step verification. You end up with one good lock instead of a dozen annoying ones.
And if you need to send one of these files on, you can always add a fresh password with Protect PDF. The guide on how to password-protect a PDF properly explains which settings are worth using.
