How to convert a password-protected PDF to images

Updated: 2026-11-02 · AnyToolsKit

Bank statements, payslips, tax forms and many e-mailed invoices arrive as password-protected PDFs. Converting them to images is easy when you know the password — and because these documents are exactly the kind you should not upload anywhere, it is worth doing locally.

Two kinds of PDF passwords

	Open password (user password)	Permissions password (owner password)
What it does	Encrypts the content; nothing can be shown without it	Asks viewers to restrict printing, copying or editing
Needed to view or convert?	Yes	No — the PDF opens normally
Typical examples	Bank statements, payslips, medical results	Published reports, e-books, forms

If your PDF opens in a viewer without asking for anything, it has at most a permissions password, and it converts like any other file.

Convert a password-protected PDF to JPG or PNG

Open PDF to JPG or PDF to PNG and drop the PDF on the box.
The file shows “This PDF is password-protected”. Type the password and click Unlock.
If the password is wrong you are told so and can try again; nothing is locked out.
Select pages, pick DPI and format, and click Convert.

The password is passed to PDF.js inside your browser to decrypt the file in memory. It is not stored, not sent anywhere, and forgotten when you close the tab. The images you download are ordinary, unprotected files — treat them with the same care as the original.

Bank and payroll PDFs often use your date of birth, part of your ID number or account number as the password. The sender’s e-mail or website usually explains the format.

Common problems

“Incorrect password” although it is right: check Caps Lock and keyboard layout (Korean/English input), and leading or trailing spaces copied from an e-mail.
The PDF uses certificate-based encryption (rare, mostly in enterprises): it can only be opened with the matching digital certificate in Adobe Acrobat, not with a password.
Pages look empty after conversion: some protected forms show content only through interactive fields. Open the PDF in a viewer, use “Print to PDF” to flatten it, then convert the new file.

What if you do not know the password?

Ask the sender for it or for an unprotected copy — banks, employers and authorities can resend documents. Strong PDF encryption (AES-256) cannot practically be broken, and trying to bypass protection on documents that are not yours may be illegal. Be wary of websites that promise to “unlock any PDF”: you would be uploading exactly the documents that most need protecting.

Keep a protected copy

Converting to images removes the protection from those copies. Store them in an encrypted folder or delete them when you are done, and keep the original password-protected PDF as your reference copy.

FAQ

Is my PDF password sent to your server?

No. There is no server involved in the conversion. The password is used by PDF.js inside your browser and discarded when you close the tab.

Can I remove the password permanently?

This tool creates images, not a new PDF. To save an unprotected PDF, open it with the password in a PDF viewer and use “Print to PDF”, if the document’s permissions allow it.
