How to use Unlock PDF: a step-by-step guide
Remove a password you already know so the file opens without prompts.
Open the free tool, follow the steps and download your result. No sign-up required.
Before you start
- One password-protected PDF within the free-plan size limit.
- The current password that opens the file.
- Permission to modify the document and share the unlocked version.
Step by step
- Upload the password-protected PDF.
- Enter the password you already have.
- Download the unlocked PDF.
Common mistakes
- Trying to unlock a file without the current password; the tool cannot bypass unknown encryption.
- Publishing the unlocked copy without checking whether the document contains confidential information.
After you download
Download the unlocked PDF and open it without a password prompt. Confirm that all pages are present before replacing or sharing the original.
Questions and answers
What if I do not know the password?
Then this tool cannot help — we do not crack or brute-force passwords.
Does unlocking change the pages?
Pages are copied into a fresh document, so content, annotations and page size are unchanged.
Is it legal to remove a password?
Only remove protection from documents you own or are authorised to modify.
